Fort DunlopBauder Total Green Roof System (BTGRS)SynopsisDuring the recent regeneration in and around Birmingham, innovation has been a key factor; a theme optimised by the redevelopment of the Dunlop Tyres warehouse which has been transformed into 45,000m² of office space and a 6,000m² hotel.Bauder Building BoardProject:Fort DunlopInvestor:Urban SplashLocation:BirminghamArea Size:7,100m2Architect:Shed KMContractor:James M Green Company LimitedThe specificationPractical challenges such as the reduction of noise pollution and maximising the building’s lifespan were all met by the Bauder Total Green Roof System with an extensive landscaping of sedum. The planting scheme provided instant coverage as the sedum was laid as pre-cultivated vegetation mats. Green roofs have excellent acoustic qualities for both external sound (up to 3dB) and internal noise (up to 8dB). This proved essentially in the selection of the Xero Flor blanket due to the proximity of Fort Dunlop to Birmingham Airport. The resultThe entire solution provided a watertight installation in conjunction with a 20-year guarantee whilst making the structure both environmentally friendly and aesthetically pleasing.System installedBauder Total Green Roof System (BTGRS) 1 BauderPLANT EA torch-applied, root resistant capping sheet.

University of BournemouthProduct: Two Bespoke Kensington Solar CanopiesCanopy Colour: Anthracite Grey RAL7016Canopy Size: 21.9m x 4.9m eachInstallation Date: September 2017The project in briefAs part of a major infrastructure development Bournemouth University created a new transport hub to connect the University to the wider area. Shelter for waiting passengers was part of the plan. Uniquely it had to fit in with the wider design themes of the development and deliver on the University’s sustainability goals by utilising solar technology. To meet those requirements Able Canopies created a bespoke canopy design based on our stylish Kensington system. The addition of solar panels, effective drainage, plus seating and under canopy wind protection, were all elements that the adaptable Kensington can handle. The result was a standout look for a practical transport hub that provides effective weather protection and longer term pay back via renewable energy generation.Growth at Bournemouth UniversityThe new Talbot Campus development at Bournemouth University is an important and prestigious project, not just for the University but for the local area which benefits from the success of the University and its students. The £3 million investment in new campus buildings and other infrastructure is a long-term commitment that will see the University widen its learning provision and all-round facilities. Part of the benefit for students, and the wider Bournemouth area, is the construction of a new transport hub that will provide joined up public transport connecting the University campus to Bournemouth itself.  A key part of the new transport hub is the weather protection provided to passengers as they wait for buses. To ensure that this essential part of the development met the standards required of the project Able Canopies entered early design discussions with the University. This evolved and in April 2017 Mildren Construction awarded Able Canopies the works for the new bus hub.Project Proposal & InstallationThroughout the development and design process we thought that our Kensington Dual pitch would be the ideal product for this installation. The more the design developed and requirements were added, such as the solar roof panels, the more convinced we were that it was perfect for the client’s needs. The Kensington is a robust, steel frame system that will stand up to all that the weather has to throw at it. Its architectural good looks mean that it makes a strong aesthetic statement, which was a key requirement here. We worked closely with the solar panel provider Polysolar who had overall control of the installation. Their panel fitted perfectly into the Kensington roof with some minor alterations to our working method to provide clean, efficient and sustainable energy for the transport hub. In addition, we had to consider how all cables were concealed and accessed at later dates. To achieve this access panels were installed in the 2 higher posts, one dealt with DC cables from the solar panels and the other with AC cables for the lighting. The final 2 lower posts on each canopy were designed to be integral rain water pipes and dispersed all water from the roof into a drainage connection below the paving.The Finished CanopiesAs the images show, the canopies look great and they are doing their job effectively in the transport hub which is now up and running. The solar panels are producing energy efficiently and help to provide a safe and comfortable shelter for the Campus’s transport users.The Tech SpecsMain Structure 21.9m x 4.9m overall canopy size (each)Powder coated and hot dip galvanised steel frame Inclined from 3m low end to 4m high end126 PS-CT Series Solar Panels per canopy (8mm thickness)Bespoke laminated glass end panelsMicro connectors to all solar panels to ensure all cabling was discreteSabre Architectural LED lightingBespoke underground drainage connectionsBespoke electrical access panels18kw system in totalGalvanised steel cable trunking & aluminium cable trays Underside Windbreaks10mm toughened glass windbreaks fixed to heavy duty steel frameGalvanised steel & hardwood benchesStainless steel glass clamps

Museum of London - Visionary RoofSynopsisThe Museum of London opened in 1976 on the historic London Wall and is a few minutes’ walk from St Paul’s Cathedral. A visionary approach to roofing had been adopted on a building that, will not only green as much of the exposed roofs as possible, but also provide a strong research aspect for future green roof projects. As with many buildings, the original roofs needed to be upgraded or replaced, at the same time as being brought up to date using environmental and sustainable solutions.Through the recommendation of waterproofing and green roof manufacturer Bauder Ltd, the Museum invited Dusty Gedge, one of the UK’s leading independent green roof consultants, to work directly with them to design 3500m² of varying habitats that encompassed the museum’s sustainable vision. and help in the provision of environments that would attract a range of wildlife, as well as being able to help the city adapt to climate change.Bauder Building BoardProject:Visionary roof, Muesum of LondonLocation:LondonProject type:RefurbishmentRoof size:9512m²Specifier:Museum of LondonRoofing contractor:Russell Trew LtdThe specificationAn independent consultant had previously carried out an energy model on the Museum of London buildings. When the museum inputted the green roof specification, it showed a potential energy saving of 10% per year, as well as a reduction on the future replacement costs of the heating and cooling plant. Some of the green roofs were funded through Drain London, a partnership project led by the Greater London Authority and funded by Defra. The project aims to better understand surface water flood risk across London, with a view to promote interventions (such as green roofs) to reduce surface water flooding. The museum has used the Bauder green roof system and worked closely with Dan Costen of Bauder and the roofing contractor Russell Trew Ltd, to deliver the various green roof spaces.These include:The refurbishment of the lower garden in the central courtyard with hard landscapingThe installation of Bauder’s new wildflower blanket to the upper garden in the central courtyard (funded through Drain London)Plug planting the roofs of the recently completed garden and terrace rooms that provide high quality corporate hire (matching the colour scheme chosen for the rotunda garden refurbishment and integrated with the new rainwater harvesting system funded by Renaissance London)An integrated sustainable urban drainage system (SuDS)Plug planting in other individual small roof areas including outside the boardroom and committee roomsTwo different planting schemes on an area of the main museum roof where the Drain London Project aims to carry out water attenuation researchThe resultRetrofitting green roofs will help to realise the Mayor of London’s ambition, to increase green cover in central London by 5% by 2030. The Museum of London is one of the largest retrofit green roof projects in the City and is certainly to be commended for allowing its roofs to be used for research purposes. Not only will it provide a benchmark for best practice, but it also demonstrates that retrofitting green roofs onto existing buildings is both environmentally and economically viable and is the way forward in helping London adapt to climate change.System installedBauderflex Green 1 BauderPLANT E 42A torch applied SBS elastomeric bitumen capping sheet.

In this case as the museum building had already been energy modelled by outside consultants, it was decided to input the green roof specification into the model. The results showed a potential energy saving of 10% per year, as well as a reduction in future replacement costs for heating and cooling plant. These factors, combined with the longer life cycle replacement of green roofs compared with normal felt roofing systems, enabled me to produce a robust business case for green roofs. With increasing energy prices the economic benefits of installing green roofs can only become more viable”Dusty Gedge added:“One of the major issues that London faces is flash floods during the summer, when sudden rainfall levels overwhelm the current drainage network. With the support of Drain London we will be researching the rainwater run-off for different green roofs. This will help us validate the kind of roofs and depth of substrates that will negate the costly effects that the sudden rainfall has on the infrastructure of the City.”

Historic music hall renovationLindab Rainline has been used by Forrest Construction on this new-build residential development project, Queens Court, which comprises of 17 one and two bedroom apartments, each with access to open space.The scheme sits on the original site of the historic Queens Hall where musicians including The Beatles and Stone Roses once played. The hall closed its doors to the public in 2004 and was demolished by the council in 2012 following a fire at the site.Architect, Denovo Design; appointed to the project by Halton Housing Trust; specified galvanised steel rainwater drainage for its durable and recyclable characteristics and to coordinate with safety railings on the upper terraces.Neil Ashworth, head of new build at Forrest said: “The development has seen us regenerate the entire Queens Hall site with new affordable homes built to a high specification of sustainability and energy saving standards”.The project received high critical acclaim, going on to win the Building Excellence Award for Best Small New Housing Development, and the Green Apple Awards Bronze Award for the Built Environment and Architectural Heritage. 

Hammerson House will be a world-class, 116-bed residential centre for the elderly Jewish Community in Hampstead. Newton Specialist Contractor Cast Contracting Ltd (CCL) were approached during the planning stages to develop a comprehensive waterproofing solution for the extensive basement.CCL recommended the installation of a Newton CDM water management system to comprehensively waterproof the extensive basement. First, they employed the 8mm Newton 508 membrane to the concrete retaining walls of the basement. The 50mm thick Fibran XPS 500-C insulation was then installed beneath more 508 membrane across the entire concrete slab. Additionally, Basedrain drainage channel was installed around the perimeter, including inspection ports to provide a fully maintainable system.This entire system is served by a series of complete sump and pump systems, each consisting of primary and backup NP400 pumps, high water level alarms, and battery backup systems. These are all controlled by Newton’s advanced Control Panel-Pro to ensure a failsafe system, even during a power outage.Finally, Newton’s 107F cementitious waterproof membrane was spray applied to the concrete upstands of the lightwells and lift pits in order to complete the continuous watertight solution.

Brett Landscaping, leading provider of high-quality hard landscape materials, has partnered with O’Brien Contractors, to supply block paving for the development of a new sports facility for the Old Saltleians Rugby Football Club in Warwickshire. The club, which was formed 95 years ago has been a fixture of West Midlands amateur rugby was required to relocate due to their original home obstructing the route of the HS2 development. With a sizeable budget at hand due to generous compensation from HS2, there were high expectations for top specification materials and an impressive finish at the new Water Orton site. O’Brien Contractors were appointed in 2021 to transform 17 acres of farmland into a state-ofthe-art sporting facility. The aim was to create a modern facility for sport and events, with the inspiration for the project being the surrounding natural environment. For Old Saltleians, this meant four high-standard grass pitches featuring advanced trench and pipe drainage (adhering to Sports England Standards), with irrigation ensuring year-round playability. The relocation included the addition of an ultra-modern clubhouse offering social spaces for the club and community to host events. This meant including extensive parking for the site was required on the site.

d² Dura Grating Mini Mesh, Dura Profile & Dura Platform 40 | Case StudyDura Composites was engaged by Premier Marinas to work with their engineering company to produce a composite floor structure around their travel hoist supported by large 305mm GRP Dura Profile beams between 6-10m in length. The team chose the GRP material over steel due to its superior performance in corrosive salt-water environments. Unique in the market, Dura Profiles exceed the higher performance E23 grade requirement of the BS EN 13706 standard.Also central to the efficient operation of the washdown and hoist are Dura Grating and Dura Platform 40 flooring made from moulded and pultruded high-performance GRP panels which are unique in design to Dura. The open mesh section utilises 55mm d2 Dura Grating Mini Mesh in dark grey, which facilitates drainage whilst maintaining strength and unrivalled anti-slip properties. The solid surface sections were created using patented d2 Dura Platform 40, which are crankable to create an in-built fall to aid water runoff.

Harmer Building Drainage, part of Alumasc Water Management Solutions, has been specified for the luxury apartments at Chelsea Bridge in Battersea. The project is the latest phase of Battersea Park Development, Vista. It is a landmark development, designed by Scott Brownrigg and built by Berkeley Homes, consisting of 1, 2, and 3 bedroom apartments, with the remaining properties ranging from £895,000 to £1.910 million – and they are selling fast. There is extensive outdoor landscaping and each group of apartments benefit from feature terraces and private balconies so they can take advantage of spectacular views over Battersea Park and towards the River Thames.Harmer’s expertise and existing relationship with Architects Scott Brownrigg and Berkeley Homes were major factors in winning the contract. Both were aware Harmer could supply a high-end product in an achievable lead time. Constant open dialogue with all parties helped get the project off to a smooth start. Accurate specification, with Harmer’s in-depth knowledge of products and issues, and close involvement at every stage, means any challenges during the project are quickly rectified. The development is due for completion in 2018.

In its largest building project in over 100 years, the Victoria and Albert Museum’s Exhibition Road Quarter achieves architectural cohesion between museum and street with the help of Alumasc Water Management Solutions (AWMS) and Alumasc Roofing Systems. In a project that demonstrates expertise across the full building envelope, Alumasc Wade HCE drainage channels and access covers were installed to provide almost invisible yet functional water management, and a bespoke hybrid roofing system installed using Hydrotech and Derbigum waterproof roofing.Designed by Stirling Prize-winning Architect Amanda Levete and her practice AL_A, the landmark project aimed to “break down the barrier” between the great cultural artery of Exhibition Road and home of over 5000 years’ worth of cultural history.The entire project encompassed the construction of the Salisbury Gallery, a flexible 1100m2 temporary exhibition space, the Blavatnik Hall, a new entrance into the V&A from Exhibition Road, the Aston Webb Screen, a newly created colonnade formed from the original 1909 structure, and the Sackler Courtyard, a key area that strives for unity between the street, the museum, the historical and the modern.

Luxury countryside holiday letsAward winning architectural practice Pocknell Studio were tasked with renovating deteriorating, redundant, two-storey structures in addition to creating new field barns to create spectacular accommodation for a fabulous countryside holiday retreat.This architect has a long-standing preference for using Rainline for their projects so it was no surprise when the galvanised steel guttering and downpipes were specified for the North and South Barns. The Silver Metallic colour option was a perfect selection for the hipped roof design with black and white palette.The field bands are finished in a contemporary take on the traditional black Essex barn and designed to fit into a typical country environment. The brick and timber clad buildings are finished with not only Lindab Rainline rainwater system but also Lindab Seamline standing seam roofing system. The valley roof and staggered fascade design was a particular challenge which required careful detailing and installation to ensure steep falls which allow rapid drainage.Bullocks Farm have tried to create “a quiet haven for people visiting the area and have made each property as comfortable, relaxing and practical as possible”. The architects are very happy that the project has been successful for the client and further development of the site will continue.  

Residential New Build apartment and spa area, consisting of 141 apartments.21 loft apartments required a design lead shower solution for which waterproof XPS round shaped floor shower elements, bathboards for tileable cladding of baths and XPS building boards were supplied in 12.5mm thickness for walls and 10mm thickness for floors.120 Apartments had XPS floor level shower elements featuring a drainage channel right next to the wall, a completely continuous slope right to the channel and more flexible adjustment for the channel. 12.5 & 10mm XPS building boards were used on walls and floors.This was the first installation that we know of in the UK where the boards in the shower area were fixed to the studwork solely by a versatile single component adhesive sealant (wedi 610), ensuring no penetrations through the boards. The special formulation is especially suited to waterproof butt joints of building boards, and has outstanding resistance to the elements; and to chemicals; and is also free of solvents, silicon and PCP.As an abP-approved system, the use of the adhesive sealant and XPS building boards reduces installation time by up to 50% because no further sealing is required, even in areas of high humidity.

Terrabase Rustic was selected for a ‘no-dig’ project creating new pathways across existing grassed, macadam and gravel areas in a popular park in Putney, London.Addagrip approved contractor True Grip Ltd was approached by the local authority to provide a quote and proposal to upgrade the existing pathways and create new paths to the Leader’s Gardens, a small public park lying alongside Putney Embankment, opened in 1903.SURFACING REQUIREMENTOne of the issues to be resolved was that the tree roots could not be disturbed so a ‘no-dig’ system had to be applied around the trees and rooted areas. For these ‘no-dig’ areas True Grip specified Addagrip’s innovative Terrabase Rustic system to be laid directly onto the existing grass and directly over the rooted areas, creating a new pathway. This meant that the trees and tree roots were not disturbed and due to the porosity of the Terrabase Rustic system, precipitation would not be reduced, irrigating the existing surface without changing the trees’ climate or environment.Over 250m2 of Terrabase Rustic Oak 6 -10mm aggregate blend was selected to provide attractive, hard wearing, natural aggregate pathways that are low maintenance, seamless and in keeping with the park setting. The porosity of the Terrabase Rustic system allows essential drainage to reach the tree roots and provide all year round access for pedestrians and wheelchair users.

Addagrip are used to seeing their surfacing systems being used for projects all over the country but it is great to see an installation being undertaken in our own town.As part of the Uckfield town centre improvements project, Addagrip approved contractor Street Tree Care Ltd was appointed to install a number of trees and SuDS compliant Resin Bound tree pit surfacing in the newly widened pavements in Uckfield High Street.Field Maple trees were selected for their compact habit, tolerance of pollution and vibrant autumn colour. Once planted, a stainless steel tray was suspended above the tree root ball and filled with a decorative resin bound porous tree pit surfacing system.The Addastone TP tree pit system consists of a 10mm aggregate bound in a PU resin which provides a hard wearing, low maintenance finish that is porous enough to let the water reach young tree roots but robust enough for the urban environment. A drainage pipe and grill was seated in the Resin Bound surfacing to assist with additional watering that will be carried out from April to September over the next few years.A 10mm Trent aggregate was selected for maximum porosity to help alleviate surface water flooding and to provide a decorative finish to complement the new York Stone pavements.

We were recently approached by Lanark Golf Club to help with creating a playable pathway directly in front of the 18th green.The existing pathway, which was finished with a rubber topped concrete tile, was causing several problems. Shots were regularly landing directly on the path and the impact was too severe causing the ball often to bounce unfairly through the green. Also the smooth surface on the existing tiles was causing balls to run excessively to the left of the green following the natural slope of the path. Lastly the existing path was not particularly suitable to play shots off or to run balls across.We worked together to identify the 45mm thick Grassflex Play tiles as a suitable replacement. Testing indicated that the impact of the ball landing directly on the tile was far more comparable to turf than the previous solution, this was due to a combination of natural compression offered by the 45mm thick rubber and the drainage channels underside offering further absorption through the air pockets created. The top surface of the Grassflex Play tile also improved the absorption as well as providing a suitable surface to play a chip shot from and to roll a ball across, the grain of the grass also removed the issue of the ball running excessively to the left.Feedback on the job has been very positive and most importantly it looks good!

Waterproofing design is a key and critical component for successful construction of below ground structures. Whether it’s a completely new build or making smaller changes to an existing property, waterproofing design should never be overlooked.Waterproofing might account for just a small fraction of a building’s total cost, but waterproofing defects can result in catastrophic consequences. When waterproofing fails, the implications are significant.Delta’s MD, Kevin Dodds was approached to offer advice and guidance on a failed waterproofing system.The existing structure had an impressive 5-level basement which houses: kitchens, food storage and food preparation areas, spa, plant rooms and accommodation. Near to a large river, the site sited well within the water table. The original waterproofing system was based on the secant piled walls and a block wall internally to provide a basic drained protection system with drainage holes at various points to drain to various levels.Over time, the third floor had become completely saturated with all levels of the basement experiencing water ingress in varying levels from damp patches to significant “jets” of water and flows of water through the secant piles.With remediation waterproofing design strategies, it may take some time to specify a suitable system. It is important that investigations are thoroughly carried out by individuals with the capability of diagnosing the defect, assessing the extent of that defect, and recommending a suitable corrective measure.

wedi Primo completes luxury in central London Hotel.The Apex Temple Court Hotel is a luxury 4 star hotel, just off Fleet Street central London. Full architectural and interior design was by Ian Springford Architects, Edinburgh.A key factor in the selection of the wedi shower units for each of the 184 bedrooms was the requirement to achieve a high performance quality waterproof bespoke solution capable of adapting to the on site conditions. Ian Springford Architects has specified wedi shower units since 2004 and Apex Temple Court is the fourth Apex hotel where they have been successfully installed. Bespoke pre-fabricated shower units - Fast installation. The key benefits of using wedi were that the Fundo shower design provided simple, fast adaption to the individual shower configurations on site, as well as the detail of enabling the units to extend under the shower door to promote drainage back into the shower area from water falling off the door when in use.Complete prefabricated shower units allow fast dry and accurate construction in ONE integrated product system rather than a combination of different individual manufacturer’s products creating the risk of potential failures between the different systems during assembly and installation. The finished result was a fast track installation of a factory prepared shower system capable of on-site adjustment, delivering a completely waterproof system backed by warranty.

Considering the large size of the basement area and its proximity to the River Thames, Newton Specialist Contractor Stonehouse were called in to provide a complete waterproofing system for the structure.At this private property in South London, the plan was to build a new basement extending below the entire footprint of the house and into the rear garden, incorporating a swimming pool, recreational spaces and wine cellar.However, considering the close proximity to the River Thames and the high water table, Newton Specialist Contractor Stonehouse were called in to provide a complete waterproofing system for the entire structure.Considering the size of the basement area, the high water table, the geographical location close to the River Thames, and the fact that the structure was created using underpinning, the risk of water penetration in this basement was extremely high. Stonehouse recommended the most failsafe solution, the Newton CDM System.Firstly, they installed Newton 508 membrane to all internal walls and the floor, using Newton's ancillary products to fix the membrane securely and seal the system. Drainage channels were also created using Newton Basedrain, feeding into a sump chamber containing two NP750 pumps, a higher capacity model capable of dealing with large volumes of water.Finally, where the basement extended beyond the house's footprint, a liquid waterproofing membrane was used on the new external roof.Stonehouse is one of Newton's oldest and most experienced specialist contractors, and they showed their expertise here by delivering a dry, safe basement for the client that could then be transformed into a beautiful new part of their home. Furthermore, the installation was backed by Stonehouse's 10-year guarantee, for complete peace of mind.

System Used - TerraSmart pedestal IGNOThe Botanist is a botanical cocktail bar in the heart of Newcastle. Complete with a rooftop terrace bar, it entices revellers and partygoers with a welcoming and curated look. The natural materials of the terrace bar, mixed with the abundance of plants and natural light, transport customers to a chic, far-off watering hole. To complement and contrast the natural materials in the industrial setting, the bare materials, exposed brick, and stone effect tiles give a suggestive canvas to the biophilic decor. The design function of the terrace is as a high foot traffic area for social meetings. To fully support the paved area in these situations, we have seen a rise in users looking for simple pedestal systems that still provide a robust substructure at an economical rate. The pedestals have a wide base acting as a stable foundation and spacer tabs that equally space the pavers apart to create drainage channels.Sasso porcelain tiles could support the primary use of the space due to their inherent properties. These porcelain paving tiles are naturally non-porous, protecting the finish from staining. This non-porous property also makes the tiles resistant to bitumen and algae. The tile also features a low slip potential in both; wet and dry conditions. Having these properties within a hospitality environment can help make a safe and long-lasting flooring surface.TerraSmart Pedestal IGNO fits into this industrial, chic environment with its simple, robust pedestal structure and hard-wearing but stylish flooring finish, punctuating the space and tying the terrace together. 

The BriefHillingdon Hospital in Uxbridge, London were undergoing a refurbishment and required additional facilities to help keep their patients, staff and visitors dry and sheltered when arriving and leaving the hospital.The project, which was managed by Kier Construction and Blue Iris Partnerships, included a number of canopies along the entrance to their emergency department where patients and ambulances arrive 24/7.A speedy installation was an important factor, because the hospital had an ever-increasing need for outside cover due to the current COVID-19 pandemic. Their staff, patients and visitors had to wait outside more frequently due to the current restrictions in place.The SolutionWhen putting our product forward to the Architect, Kier Construction explained that while our product wasn’t specified, the main features were in fact equal to the specified product and are designed for use in commercial settings, making it the perfect solution.This product is the Coniston Wall Mounted Canopy which is an extremely versatile, commercial grade structure that met all the features required by both the Architect and the hospital including: A mono-pitch structure, integral guttering and drainage to the ground floor with no visible gutters, constructed from 100% non-corrosive material (aluminium) and a non-fragile polycarbonate roof system.Even though the Coniston is a wall mounted structure, some of the canopies detailed in this project needed to be free standing as the existing ramp that the canopy would cover is a distance from the wall. This was not an issue as the Coniston can be installed with rear posts transforming it into a free standing canopy.

The Host Helix building, also known as the “Helter-Skelter,” was a unique and striking structure built in 2011 with stunning views of North London and Wembley Stadium. Over time, the building experienced general wear and tear and water began to enter the buildings’ complex structure.Polyroof Products were called in to consult with the clients and offer a seamless, encapsulated solution that could address the many unusual details associated with the building’s design.The SolutionA full survey of the roof terrace areas was conducted by the Polyroof Technical Services, after which a bespoke specification was produced for the works. The proposal document detailed a comprehensive set of recommendations for producing a seamless solution to encapsulate the problematic roof, therefore solving the issues that had arisen over the years due to its condition and age, as well as the issues associated with the original design of the pitched, curved roof.Polyroof SA Carrier Layer was then applied over the cement particle boards with Polyroof pre-formed GRP Drip Trims fixed to the external edge. For continuity and to create a uniform finish, the SA Carrier Layer was extended onto the main roof sections as a substrate for the Protec system.Any details requiring local reinforcement were treated with Protec Resin and 75mm wide Polymat 450. The curing process was allowed to take place. To accommodate structural expansion / contraction movements at appropriate details, 25mm disbondment tape was installed prior to local reinforcements.The first coat of Protec Resin and Polymat 450 was applied at a minimum coverage rate of 1.3 – 1.5Litres/m² (0.66 – 0.77m²/Litre) and was allowed to cure. To complete the system, a second coat of Protec Resin was applied at a minimum coverage rate of 0.5Litres/m² (2.0m²/Litre) and was allowed to cure.ComplexitySuch an iconic building in the local community, the client wanted to protect the original aspects of the building to the fullest extent, so the Protec system installed at the perimeter was color-matched to the original blue and grey colours. This was achieved by blending pigments until they matched the desired colors, in turn the pigment was then blended into the Protec resin before application. The survey revealed concerns about the original building designs from 2011 and the roof’s drainage system. Due to the roof’s pitch, rainwater was cascading down the curved slopes at high velocity and causing water to bounce into the building under the original capping.After many discussions between the main contractor and Polyroof, as well as the provider of the external cladding, it was agreed that the perimeter detail needed to be encapsulated with the new waterproofing system to prevent further water ingress. Fire-retardant cement particle boards were fixed to the internal and top faces of the external parapet walls, and the Polyroof SA Carrier Layer was applied over them with Polyroof pre-formed GRP Drip Trims fixed to the external edge.The Protec System was then applied to encapsulate the entire parapet detail, meaning its waterproof integrity would be covered under the Polyroof Guarantee. The curvature of the building added complexity to this process, and the contractor took great care in cutting the trims to size and fixing them to the external edge to ensure they followed the profile of the structure. Due to the building’s height, all the trims were face-fixed to prevent wind uplift.WorkmanshipIn order to improve drainage and prevent water from accumulating in hotspot areas of the roof, the contractors were instructed to install new internal curved gutter channels at the point where the roof and building met. These channels were designed to have a sufficient height and angle to effectively direct rainwater towards the outlets, preventing water from pooling on the roof. However, the installation process was made more complex due to the curved nature of the building’s architecture, which required careful measurement and customization of the gutter channels to fit the unique shape of the building.Additionally, the contractors had to consider the many joins of the gutters and how they would hold up to the elements over time as the building structure expands, contracts and moves. Extra steps were taken to ensure the gutters liquid membrane was properly sealed and secured to prevent leaks.The contractors were instructed to repair all protrusion and mansafe post details as necessary in order to allow the Protec System to be installed to a minimum height of 150mm, and to terminate it underneath a suitable weathering flange or jubilee clip. In addition, all right angles were to be reinforced with double taping. Any protrusions that were liable to significant movement was required to have disbondment i.e., bond break, tape applied to it to stop the external coating from stressing on expansion. Furthermore, all pipes were to be abraded, solvent wiped, and where necessary, primed in accordance with the Polyroof coatings manual. A flashing detail was also to be created with a weathering flange or seal.All outlets were inspected to ensure that they were functioning properly. Any outlets that were deemed unsuitable were replaced with new ones. The outlets were cleaned, prepared, and primed as necessary. The Protec system was then dressed into the outlets as far as was practical. The inspection and replacement of the outlets and the preparation of the Protec system helped to ensure that the drainage system functioned effectively.ConclusionThe refurbishment of the roof was completed within the client’s target timeframe and budget. Following a final inspection by Polyroof Technical Services, which highlighted quality workmanship of Tower Asphalt Ltd, the client received Polyroof’s trusted Accredited System Guarantee and now has the peace of mind the roof will be leak-free for decades to come.

As part of their ongoing relationship with Imperial College London, Newton Specialist Contractor A.P. Gooch assessed and waterproofed 11 Victorian brick vaults beneath the streets of Kensington, London, after the existing competitor ‘waterproof render’ failed.Imperial College London is a world top ten university, and it's top-class educational facilities in Central London are constantly used by multidisciplinary students, including doctors, and nurses, for their studies. It was therefore crucial for AP. Gooch to perform the work whilst also creating minimum disruption to the college students.Following a full assessment of the vaults, A.P. Gooch decided that the best option was to install the tried and tested ‘failsafe’ Newton System 500 cavity drainage membrane solution in order to depressurise, capture and safely manage ingressing water away from the building. A.P. Gooch also committed to carrying out the entire installation at night in order to cause as little disruption as possible to the College’s students.By installing Newton 508 membrane with strategically placed Newton MultiPlug fixings, the system remained sympathetic to the historic structure beneath. Newton Basedrain was also installed in order to channel captured water to one of four Newton Titan-2 sump chambers, the compact size of which made them ideal for use in a structure with such tight size restrictions. Each chamber also contained primary and backup Newton CP400 pumps to ensure that there will always be a safe means of removing captured water from the building.Now fully protected by a maintainable system, compliant with waterproofing code of practice BS 8102:2009, all 11 vaults are now completely dry, providing safe and healthy individual study rooms for the medical students at Imperial College.

A small farm cottage in a Cornish Village has been transformed with a stunning large modern extension and balcony.The team of Camel Glass installers have been heavily involved in this home with the installation of windows, doors and the glass balustrade. This home is situated on the grounds of an old quarry, with views over the valley towards an engine house. The customers wanted to be able to enjoy their view to the maximum and using glass balustrade provides a safe and solid railing. This home is highlighted throughout with copper oxide furnishings, the front door and elements of the kitchen follow this theme while the sink splash back is made from glass petals in a beautiful glass meadow scene. The balcony glass was the last outside job to be done, having to wait for the kitchen counter to be installed through the French doors it was safer to install the glass after this had been carried over the balcony. Now that winter is coming the indoor jobs can be finished off and the home owners can enjoy their newly renovated home! This installer has used POSIglaze base-fix in black. Balcony Seal® has also been used to ensure water can run off the balcony under the channel without causing water ingress. Most balconies and flat roofs are built with a slight pitch to encourage rainwater to drain towards the edge of the roof. In these cases, the balustrade installer needs to allow for drainage points under the channel, to avoid water pooling around the edge of it. The Balcony Seal® system works by subtly raising the channel a few millimeters above the substrate on drain blocks. Notches on the top side of the drain blocks locate into the rebates of the POSIglaze channel, locking it into position before the system is bolt-fixed to the substrate through each block.

When Brexit terms were finally decided in 2020, the end to the freedom and movement of EU goods was agreed to begin from the 1st January 2021. HMRC therefore required an Inland Border Facility to be urgently mobilised to perform the new series of checks required on HGVs crossing the UK Border at the Port of Dover and the Channel Tunnel. This site acts as a location for checking movements of goods inbound (Defra and HMRC) and outbound (HMRC only).Each location is to include parking areas for HGVs and other vehicles, with security measures and facilities to enable the checking of vehicles and goods entering and exiting the sites. There are also temporary office buildings, staff and driver welfare amenities.The design of the facility onto 48ha of former agricultural land was developed with a view to maintaining the landscape and biodiversity of the surrounding area and to screen views of the site from the local villages.Excavated materials were sustainably reused as part of this process in order to create bunds, whilst surface water drainage of the site is directed to local wildlife ponds and wetlands via 30,000 square metres of aggregate filled Truckcell cellular paving.The site is trafficked by up to 950 HGVs at any one time and provides a free-draining, sustainable and durable SuDS surface to withstand the traffic levels without damage or abrasion.Throughout the project, ABG’s in house technical team provided design guidance and site installation support for the customer. Truckcell is a heavy duty cellular paving system manufactured from 100% recycled and recyclable plastic, capable of sustaining frequent HGV loads up to GVW 60 and 10 tonne wheels loads. It can be filled with angular gravel (as was the case on this project) or topsoil and grass seeded, according to the application.

Laying ceramic tiles on flat roofs, terraces and podium decks has been made easier with the development of the Rail System, an integrated substructure system to increase stability of suspended tiles. The Rail System incorporates an adjustable height pedestal with a special clip head fitting, a specially profiled aluminium rail which clicks onto the headpiece without the need for mechanical fixings and a top headpiece which slides along the rail to hold and position the tile. By tying the pedestals together via the rail, there is far less risk of an individual pedestal moving or changing height, leading to far less risk of a tile rocking over time. This assures the integrity of the upper surface and gives a health and safety improvement to the area.The rail gives added structural stability as the weight is distributed laterally along the rails and not driven directly downwards onto the pedestal beneath. The top headpiece can be slid along the rail to fit to the corners of the tile above. This means the edge of the tile does not necessarily have to be directly above the pedestal, giving much greater flexibility for positioning.Consider the possibility of a drainage outlet or other awkward detail being directly beneath the edge of a surface tile. Instead of having to cut the tile back, simply move the pedestals away for the outlet and let the rail circumvent the hazard. Position the top head in the correct place to fit around the corner of the tile and the issue is addressed quickly, securely and easily. The rail system brings greater lateral stability to the tiled deck and is a faster, more efficient way to lay porcelain tiles and slabs. It is a major technical improvement to suspended tile and slab installations.

Fulham JettyBauder Bakor 790-11 hot melt structural system with Bauderflex waterproofing system and BauderGREEN sedum systemSynopsisFulham Wharf is a landmark regeneration scheme that began in 2013 and included the ecological enhancement of an abandoned jetty on the River Thames. This redevelopment was designed to provide the local community with an ecological education centre and bio-diverse wildlife reserve.Bauder Building BoardProject:Fulham JettyLocation:LondonRoof Area:1,000m²Specifier:FabrikApproved Contractor:Accurate RoofingProject challenges One of the major challenges for this roof was installing the central sloped section, which required exceptional levels of technical input and workmanship. This roofing area was waterproofed with the same bituminous green roof system as the upper roof; however a special timber design for retaining the substrate and sedum blanket was also needed. Since its official opening in October 2013, the lower wildflower roof has become a haven for a variety of different birds and insects.The resultThe building’s new roof swoops down to become a continuum with the jetty deck and is covered with a green habitat providing three distinct environments for wildlife; one on the flat roof, one on the slope and the third on the jetty deck. The education centre roof was waterproofed with Bauder’s root resistant bitumen membrane before then having a sedum blanket fitted. On the lower roof, 650m² of Bauder’s hot melt structural waterproofing was installed along with a wildflower blanket, providing an instant carpet of vegetation. Systems installedBauderflex bituminous waterproofing system1 BauderPLANT E 42A torch applied, SBS elastomeric bitumen capping sheet.

The completion of a stunning new Hilton hotel at Silverstone is another step nearer and leads the way featuring the superior high-performance Wraptite external airtightness barrier.The impressive new hotel, located trackside, overlooks the starting grid for the home of the iconic British Grand Prix. Facilities include 197 guest rooms, a rooftop terrace and the offer of race-day hospitality experiences.KKA Architecture designed the hotel, with Metclad Contracts appointed as the specialist envelope contractor for the project.Wraptite airtightness membrane from the A. Proctor Group, specialists in supplying high-performance products to protect buildings, was selected by Metclad to maximise airtightness and energy efficiency, perfectly balanced with the crucial requirements of vapour permeabilityWraptite self-adhesive breather membrane is applied externally, quickly and efficiently as part of the rainscreen system. Incorporating the Wraptite System helps ensure “as-designed” performance. Its inclusion narrows the gap between asdesigned and actual energy performance whilst reducing the likelihood of possible failures to meet required airtightness levels.Traditionally air barriers have been fitted internally. The internal installation of an air barrier necessitates accommodating building services such as electrical, lighting, heating and drainage systems, thereby increasing the gap between as designed and built. However, the Wraptite membrane fully bonds externally to virtually any substrate, requiring no additional mechanical attachment, seals or tapes to suppress air leakage around junctions or penetrations.The high vapour permeability of Wraptite allows the substrate beneath to dry quickly and moisture vapour to escape and reduces the likelihood of mould, mildew, condensation, timber distortion and metal corrosion.Wraptite is the only self-adhering vapour permeable air barrier certified by the BBA and combines the critical properties of vapour permeability and airtightness in one self-adhering membrane. Quite simply, providing a winning performance in advanced membrane technology for buildings.

Balance pedestals form Wallbarn provide ultimate in precision and performance for roof terrace construction.This large roof terrace in a luxury residential redevelopment of a commercial block next to the Royal Courts of Justice demanded a high end finish. The roof deck had been waterproofed and insulated and 50mm limestone slabs needed to be raised and supported to achieve optimum drainage and ventilation to the structure.The client wanted a flat upper surface with no ridges or interruptions between individual slabs and the Balance self-levelling pedestals were able to create a smooth upper surface with reduced trip hazard and more attractive aesthetics across the terrace.The self-levelling nature of the headpiece meant any blemishes on the surface beneath such as laps between the waterproofing layers and drains, services etc. were accommodated easily without any noticeable effect on the upper surface.Because the self-levelling headpiece has an optic type mechanism it moves in all directions and achieves a perfectly flat upper level by itself, there is no need for installers to wind up and down separate segments of the head. it creates a better finish in much less time. The installer on this project simply loves Balance and will not use any other brand for self-levelling solutions. The limestone slabs were installed in a staggered layout and the Balance pedestals coped with this easily as the positioning lugs could be snapped off at T junction and other detail areas to create clean finishes. Weight tolerance was a major issue as heavy planters, a large barbecue, seating and other furniture were to be placed onto the slabs. Balance pedestals have a normal weight tolerance of 683kg each and a break point of over 1 tonne, so could cope with the additional weight easily. The end result was stunning. The client was delighted with the result and used this terrace on the show flat for the whole development.

CHALLENGE The first of its kind for Quebec, the “living street” required a paving grid that would provide multi-purpose access along the street whilst also allowing for the aesthetically pleasing natural look to be maintained. A woonerf is a living street that is traditionally implemented as a traffic calming aid and to enforce low speed limit areas. They are often shared space streets where equal priority is given to all modes of transportation including automobiles, bicycles and pedestrians; usually with separate rights of way. The province of Quebec was looking to do a “pilot project” in the city of Montreal to create a woonerf that would not only provide the required access, including disabled access but that would also have a long-lasting beneficial impact on the environment. They were looking for an environmentally friendly ground reinforcement product which would provide the strength and durability required for a heavily used area. As a “living street”, the product needed to allow the growth of natural vegetation and contain no harmful preservatives which could affect the environment in which it is placed. The harsh weather conditions in Quebec also needed to be considered. With such extreme conditions in both winter and summer, the material needed to withstand the temperature fluctuations. Ground reinforcement products traditionally used such as concrete are susceptible to cold crack in winter as it is a porous material. As a requirement, the desired product was to absorb only limited heat in order to promote growing vegetation. The only suitable material for a project with such challenging conditions was hanit®’s recycled plastic heavy duty ground girds, with their durability and environmental credentials meeting the requirements.SOLUTIONhanit®’s Heavy Duty Ground Grids are manufactured from a blend of high-quality recycled plastic polyolefins extracted from post-industrial and post-consumer mixed waste plastics. Heavy Duty Ground Grids have a high impact resistance which makes them suitable for all vehicle access. They have an interlocking system which improves stability and also allows for quick and simple installation. As the woonerf needed to provide numerous different access levels it was important that the Heavy Duty Ground Grids were versatile. They can be filled with either grass, seed/topsoil or gravel. For this project, wheelchair access was provided through a gravel filled pathway.The rest of the “living street” was mostly completed with grass filled areas. As hanit® products transfer limited amounts of heat, they dry out the soil less than concrete. This works as a benefit to the vegetation growing through the grids. Recycled plastic material is not porous and therefore does not absorb any moisture. This gives added benefits in the winter as when absorbed moisture freezes in concrete it causes cold crack. Their open structure also allows for quick infiltration of any rainwater into the ground allowing for sustainable urban drainage requirements to be met.hanit® Heavy Duty Ground Grids are strong and durable and require no maintenance. They are not affected by weathering and decay; therefore once in place, they have a much longer lifespan than any other competing products. Made from 100% recycled material, the woonerf has been an extremely sustainable project. Providing Montreal with a living street has not only added more vegetation to the area but also allows the city to contribute to an environmentally responsible sustainable urban drainage solution. As the products are chemically inert they do not affect the environment and are harmless to all flora and fauna. In total the project has used 8,500 units of Heavy Duty Ground Grids. This equates to almost 77 tonnes of recycled plastic waste which has been saved from going to landfill. The woonerf has been an extremely well celebrated project that has won prizes for its conception and green initiatives. “I recommend Les Dalles Vertes (Heavy Duty Ground Grids) to all my clients. We laid out nearly 30,000 square feet of these pavers for the Woonerf project and it took us half the time and resources that were required to install the old concrete grass pavers." - Tony Scirocco, Ventec

Heavy rainfall on the Orkney Islands meant that the basement room of Kirkwall Air Traffic Control Tower suffered from frequent flooding, with water levels reaching 1.2m at their highest point. Newton Waterproofing and Specialist Contractor Wise Basement Systems were called in to remove the existing water and then waterproof the structure to protect it from future flooding, all in just one week.Kirkwall airport is located on the main island of the Orkneys, 10-miles off the North coast of Scotland. Presented with a logistically challenging location and a tight project timescale of just 1 week, Newton had no hesitation in recommending the expertise of Wise Basement Systems as the specialist contractor to Building Surveyor Pick Everard.Getting involved at the very start of the project, Wise were immediately able to design, advise on and install a system to remedy the 2 inches of water in the existing basement of the Air Traffic Control tower.Cavity Drain Waterproofing, or ‘Type C’ waterproofing as it is defined by BS 8102:2009 is often the most effective means of achieving a completely dry ‘Grade 3’ environment in an existing structure below ground. It was therefore no surprise that Wise Basement Systems designed a Newton CDM System for this existing basement area.To begin, Wise installed 120m2 of Newton 508 on the walls and 80m2 of the recycled Newton 520 eco to the floor, above the closed-cell Fibran XPS 500-C insulation. The drainage membranes were supplemented with a perimeter channel of Newton Basedrain, directed to a Titan-Pro sump chamber containing two NP400 Pumps to remove the water.Finally, to ensure that the system will continue to work in all eventualities, even in a complete power outage, Wise installed a backup system with dual Northstar batteries and a Victron Power Inverter.Even with a project located 10 miles from the mainland, and 1 week to waterproof a basement with only a 600mm wide access hatch, Wise Basement Systems delivered a completely dry space for the client that was also compliant with BS 8102:2009 and backed by their guarantee.

Having purchased the lands from the Golf Club, Cosgrave Developments wanted to ensure the natural contours of the existing grounds were maintained when building the public amenity park – Honeypark – which is the centrepiece of their development.As a focal meeting point the area contained mature parklands with a man-made lake and childrens play area as the main attraction. With this area being lower in the development a safe, durable and visually pleasing design was needed, Mick Cosgrave chose AG’s Ground TerraPave® natural aggregate flags to meet the specification, with its durable finish and low slip resistance it met all the safety criteria for this major walkway.When laid it’s visually impressive surface draws you to the central focal point of the scheme. To improve safety for the visually impaired AG’s smooth bullnose kerbs setts were used to form the numerous step details complimenting the smooth crisp clean appearance of the paving and flags.The main green space areas also had sloping contours where soil retention was needed to aid structural integrity and drainage, AG’s Vertica Retaining Wall system was selected. The low rise walls meet the engineering specification whilst the choice of colour was in line with the design choice for the scheme. The unique split level design also provided a natural amphitheatre and seating area for the residents, the low level of the walling kept in mind the safety aspects for younger children in the area.In the main residential areas Cosgrave Developments choose AG’s River Stone Blackwater paving for the parking bay areas. Unique in its design due to its undulating face finish this new product has the key benefits of smooth paving, tight joints and an extra sparkle due to the addition of natural granite chippings. Technically its ideal for the durability and hard wearing required to take parked vehicular traffic over long periods of time

Red Mill was originally known as Reedham Ferry drainage mill which was built in the1840s with common sails to drive a single scoop wheel and was brought to wind witha tail pole. In the 1890’s the millwrights England, modernised the machinery andfitted double shuttered patent sails. The Norfolk boat shaped cap held a fantail.In the 1950’s the mill, then derelict was purchased and turned into a sunnyresidence.More recently the Mill was purchased by Laura and John, a youngcouple whose wish was to turn it into a unique, quirky home, set in astunning location.The mill was covered in an impervious, damaging, cement renderand painted red with a modern, non-breathable masonry paint. Theeffect of this was to trap high levels of moisture in the brickwork,making the interior damp and cold.The owners wanted to do the right thing for the building, so setabout the long, hard labour of love that was hand stripping it all backto the original red brick, internally and externally.Best of Lime were contacted by Laura and John to come up withsuitable products to reinstate the external lime render and internallime plaster.After visiting site, it was decided that externally, the mill neededRendercote, a robust lime render developed for high exposuremasonry. Internally, the dubbing out and base coat would beinsulated Warmcote, with a Limecote finish to give a visually softlook.Maltby Plastering Ltd , traditional lime plasterers were chosen tocarry out the project.Internally, Laura and John wanted to contrast the soft curves of theLimecote with a hint of the industrial origins of the mill, so checkerplate steel was used for sills and the staircases, to give a greatvisual effect.Externally, the Rendercote is trowel finished smooth, expertlyapplied by the Maltby Team on a difficult continuous curve.The finished work was decorated with the breathable, low carbonGraphenstone system.Overall a very satisfying project to be involved in, from a poorlyfunctioning, damp shell to a very smart, warm, dry comfortableand unique home in a beautiful location.
