"rainwater"

Apex Heritage Cast Iron rainwater system from leading specialist Alumasc was commissioned as part of the £800 million extension and restoration of St Pancras International, London.The extension and interior of the station comprised all the modern facilities expected in Britain’s most advanced station, however, work on the oldest Grade 1 listed part of the station called for the faithful and painstaking restoration of the gothic red brick façade, to retain the original detail of George Gilbert Scott’s design.Existing rainwater systems, despite being almost 150 years old, were still in use. As part of the redevelopment project English Heritage insisted that any new rainwater details must faithfully reproduce the original patterns of the Victorian rainwater goods used when the station was first built. Alumasc worked closely with the main contractors to produce bespoke moulds, creating cast iron replicas of all the existing pipes and hoppers to take away rainwater from the vast single span roof, which is still the largest of its type in the world.

Conningbrook Lakes is a modern development of what will be over 300 new, state of the art homes, situated beside the beautiful lakes and rural scenery of Ashford, Kent.A timeless reimagining of the traditional Kentish village, a variety of homes to suit all tastes and lifestyles have been created using Alumasc Rainwater Infinity steel gutters and downpipes.Phil Lapping, Regional Sales Manager and Estimator at Gutterworks Limited, who supplied all rainwater management systems, said: “This beautiful new development deserves nothing less than the best.“Having been built to a high standard by Chartway Construction on behalf of Westerhill Homes and Latimer, it was specified that all water management was to maintain the overall look and feel of each property. On many of the houses there are modern stainless-steel balconies, therefore, to put plastic gutters and drainpipes on these houses, although functional, just wouldn’t look right.“Additionally, the environmental benefits of a steel system vastly outweigh that of a plastic system, which was an important factor in the decision-making process.”Alumasc Rainwater Infinity stainless steel gutters and drainpipes were the most natural choice.Finishing the houses to the best standard possible meant ensuring all accessories matched and upheld the high standards of Chartway Construction and Alumasc.Rainwater Infinity Steel was developed by Alumasc to offer a contemporary, eco-friendly and cost-effective alternative to plastic gutters, that look sleek and have no risk of shrinking, leaking or colour fading.

David Austin Roses, award winning rose growers and home of the National Rose Collection, has recently installed Alumasc Rainwater steel gutters and downpipes at its nursery tea rooms in Shrewsbury. Following a recent extension they wanted to give the property a new lease of life as the existing plastic rainwater was becoming unsightly and tired. Rainwater specialists Roweaver Developments Ltd recommended the perfect solution for David Austin Roses with Alumasc’s contemporary steel range. The replacement steel guttering complements the timber cladding of the building and fits in with the overall look of its well-kept gardens.

The new clubhouse of the Machrihanish Golf Course has had its water management upgraded thanks to the installation of two Alumasc Rainwater products: Aqualine Box Extruded Aluminium Gutter and Flushjoint Aluminium downpipesThe golf course, founded in 1876, recently had its clubhouse rebuilt after a fire in December 2018 destroyed the original building. Local contractor McKinven and Colville Ltd carried out the work on the new clubhouse which was designed by G1 Architects. The building offers unparalleled panoramic views across the Championship and Pans courses.“For this project, two Rainwater products, Aqualine Box and Flushjoint were specified and installed for the new clubhouse on the golf course,” said Nicola McGowan, Area Sales Manager, Scotland. “It’s an elegant, modern building with stunning views over the Atlantic.“The Aqualine Box Extruded Aluminium Gutter and Flushjoint downpipes were chosen for their sleek, modern design, and durable, non-corrodible features.”

Excellent service and communication sees Broomfield Primary School extension completed on time with AlumascBroomfield Primary School in Essex has benefitted from multiple water management installations from Alumasc to complete its brand-new extension. These included Skyline aluminium Fascia and Soffits, GX pressed aluminium box gutters and Flushjoint aluminium downpipes.The specification of the integrated ‘Rain to Drain’ Alumasc Skyline and Rainwater ranges came as a result of Alumasc’s highly regarded product offer and strong working relationship with subcontractor on the project, Ipswich based Specialised Fixings Ltd.John Hemphill, Technical Sales Manager at Alumasc, explained: “Specialised Fixings is one of our Alumasc recommended installers that we have collaborated with on many projects.“This good working relationship which hinges on a high level of communication and readily available service and support from our products and technical teams, is what ensured we finished this project on time, to the highest specification.“Meeting deadlines can be a challenge for some ambitious projects, but certainly this year it has been for the whole industry!John continued: “We are very proud that our Alumasc Technical Services and Technical Sales Managers are able to provide such in depth help and support to our recommended installers and subcontractors, which benefits them out in the marketplace."

The former Holmlea Primary School is one of Glasgow’s most distinctive residential developments, comprising Alumasc’s Heritage Cast Aluminium rainwater system, in a remarkable blend of conservation and new build construction.Originally designed by Andrew Balfour and opened in 1908, the school formally closed in 2004 and the site was disused for 15 years before finally finding a new owner in Home Group. The developer purchased the site with the intention of repurposing both the original school building and the janitor’s house, which is Category B Listed, for rented housing, and the all-new construction of an extension and two new blocks. In total, the redevelopment presents a total of 49 homes, in a mix of social and affordable rent.Architects on the project Anderson Bell + Christie worked closely with Historic Environment Scotland to deliver a sympathetic restoration and addition to the existing building, to bring the building back into use and provide much needed housing to the area.

Integrated Alumasc Water Management Solutions specified on new mixed-use development.The site of a derelict petrol station located in the historical town of Hemel Hempstead has recently been transformed into a new retail and residential development.Bovingdon High Street now features eight brand new apartments and a new Tesco express outlet, bringing new life into the once disused space near the town centre.The unique design of the site coupled with the number of dwellings planned, saw a number of challenging design factors for the project, including curved roofs and the need for soffits within a confined space.This is where Alumasc Water Management Solutions (AWMS) come into their own, offering a complete solution. An integrated Skyline and Rainwater offering was specified across the development, including Skyline’s bespoke aluminium fascia, soffits & copings. AX moulded extruded gutter systems with combined Swaged downpipes where also part of the final specification. All finished in a BBA approved, polyester powder coated finish, the final look achieved demonstrates understated quality, in dusty grey colour (RAL 7037) specifically to match the windows and balconies on the project.“Thankfully we were consulted early in the project, which is where we are most effective,” commented John Hemphill, Skyline Technical Sales Manager, who worked on the project.“We had a number of site meetings, which resulted in designing and submitting CAD and 3D drawings in order to ensure the project was delivered on time.”

Stowford Mill, built in 1787, is one of Devon’s oldest historic industrial sites to still be expanding.Because of its iconic features and characteristic atmosphere, Stowford Mill has long been established as one of the trendiest places to work, eat and shop, bringing commerce and prosperity to the surrounding area, and forcing the town to expand to make room for tourists who just never wanted to leave.Part of this expansion will eventually include Burrington Estates’ eight-acre vibrant community of contemporary new homes. This new development, for which the main contractor is URBN, is due for completion in 2023.Started in March 2018, the existing homes already include Alumasc Rainwater Infinity Steel gutters and downpipes, specified to provide eco-friendly, discreet and resilient water management that will last. Crucially, this system was favoured to the use of plastic systems, to meet the demand for a readily available product that was both environmentally- and price-conscious.As the new development creates a unique new environment in which to live, work and relax in the midst of the historic area, the most important part of the project was to keep the best of the stunning architectural heritage already there, whilst finding innovative ways to incorporate the latest modern building design. Helping to bridge this gap between the historic and the modern, AWMS offered a solution.“Alumasc systems were chosen as it was the project’s requirements to specifically use steel for gutters and downpipes,” David Loader, Key Account Manager at Alumasc, explained.

Before there was an open, 4" (100mm) diameter pipe that drained water from the back of this Devon farm house into the yard. Apart from an open pipe, which never looks good on a listed building, when it rained heavily there was water gushing out across the road causing havoc to any cars parked nearby. With the installation of the cast iron cowled conservation vent now the water is deflected downwards and the opening is no longer open to the elements and in eye line. With a choice of 100mm or 125mm spigots this cowled vent has many uses

This case study highlights the successful implementation of Britmet’s flat-to-pitch conversion system, BritFrame, and lightweight metal roof tile, Slate 2000. The project, carried out by Jennings Roofing encompassed a total area of 500 square meters and aimed to improve the infrastructure of the existing roof. This case study examines the benefits, challenges, and outcomes of utilising Slate 2000. This case study highlights the successful implementation of Britmet's Slate 2000 roofing system and Britframe structural solution in a social housing project. The client, a new customer of Britmet, discovered the systems at the UK Construction Week (UKCW) exhibition. Impressed by the innovative design and features, the client expressed interest in utilising Britframe for a flat-to-pitch conversion project in their social housing development. The client is a housing association responsible for managing and maintaining a portfolio of social housing properties. They were seeking an effective solution to address various issues with one of their buildings, including an ageing roof with multiple repairs, inadequate insulation, and inefficient rainwater management. The objective was to enhance the building's aesthetics, improve water tightness, increase energy efficiency, and minimize future maintenance requirements. The initial meeting between the client and Britmet took place at the UKCW exhibition, where the client became acquainted with Britframe, a lightweight and versatile structural solution. Intrigued by its potential, the client arranged for an on-site visit to further assess the feasibility of utilising the Britframe and Slate 2000 roofing system for their project.Slate 2000 is a durable and aesthetically pleasing lightweight roofing material that offers long-term performance and weather resistance. It's stylish design and robust properties make it an ideal choice for enhancing the visual appeal and durability of roofs and cladding. During the initial site visit, Britmet's team evaluated the existing roof condition, rainwater management system, and insulation levels. After careful assessment, they provided the client with a budget price estimate for the proposed project. The estimate included the cost of materials, labour, and necessary ancillary items. To streamline the project, the client signed a Project Assist agreement with Britmet. This allowed Britmet to obtain planning drawings and submit the necessary applications on behalf of the client. Additionally, Britmet provided structural calculations, design drawings, and rainwater calculations to ensure compliance with regulatory standards and best practices. The main objective of the project was to convert the existing flat roof to a pitched roof using Britframe and install Britmet's Slate 2000 roofing system. This conversion offered numerous advantages, including improved water tightness, increased insulation, and resolved rainwater management issues. Notably, the internal gutters, which had caused maintenance problems, were relocated externally as part of the new design.Beyond functionality, the new roofing system and structural solution significantly enhanced the building's aesthetic appeal. The modern design of Britframe, combined with the stylish appearance of Slate 2000, seamlessly integrated the property with its surroundings. The improved visual aesthetics added value to the social housing development. One of the key benefits of choosing Britmet's Slate 2000 and Britframe was the assurance of minimal maintenance requirements. Unlike the previous roof covering, which had undergone numerous repairs and reached the end of its life, the new system was designed to be durable and long-lasting. This eliminated the need for ongoing maintenance and reduced future costs for the housing association.Through the adoption of Britmet's Slate 2000 roofing system and Britframe structural solution, the social housing project achieved its objectives of enhanced aesthetics, improved water tightness, increased insulation, and efficient rainwater management. The collaboration between the client and Britmet, from the initial meeting at UKCW to the successful implementation of the project, demonstrated the value of innovative roofing and structural solutions in the social housing sector.

Eco conscious barn conversion Landscape Design company Gardens Sorted specialise in renovation and bespoke garden installations. This project is a former farmyard and threshing barn conversion, the brief was to follow sustainable principles, the artifacts used around the garden are largely reclaimed, reused or recycled agricultural items.The client gardens by organic principles therefore the need for non-PVC galvanised rainwater goods was paramount. Chris Bligh, designer and installer at Gardens Sorted describes the installation: ”The rainwater solution required the high roof gutters to be deep profile, maintenance free, non-blocking outlets, and a long elegant downpipe into the storn water drain accross the yard. The addition of a rainwater diverter at the lower section afforded connection to a pressure water hose under grounded to two bends emptying into a reclaimed galvanised water tank. The hose is always full of water to the height of the tank. The important value of this is that the client can then dunk a large watering can into the deep water at waist height.” Chris adds that Lindab’s Rainline products are very good and he was grateful for a high standard of customer service.

The Merry Hill Shopping Centre in Brierley Hill recently underwent an expansion and overhaul of its entrance area. Aspen were approached to design, manufacture and install bespoke drainage for the newly renovated entrance area to the shopping centre.Aspen worked closely with the client to manufacture and install stainless steel solutions to support the performance of the outdoor environment. There was great importance placed on the rainwater calculations and anti-slip resistance to ensure the channels and covers were fit for purpose in an outdoor setting. Aspen provided engineering drawings, samples and prototypes to ensure a seamless manufacturing process and delivery of the project from day one.Aspen Stainless  HD Heel Guard Drain Cover and Drain Channels were specifically designed to support the flow of rainwater within the entrance area. The standard central bottom Meribel Outlet was installed to efficiently dispose of non-liquid waste built up within the outlet. The trap featured fully removable trash baskets to allow for the efficient disposal of non-liquid waste, built up within the outlet.The HD Heel Guard Cover was specifically tested using the pendulum anti-slip test. The pendulum assesses the friction offered by the floor when a foot comes into contact with the surface. The cover was tested to ensure that the surface presents a safe level of grip in end use. The pendulum anti-slip has proven to deliver the most accurate results and is therefore the key adopted method for assessing floor slipperiness in all conditions. The pendulum CoF test is the subject is a British Standard, BS 7976: Parts 1-3 using an imitation heel (rubber soling sample) sweeping over the drain cover. The slipperiness of the flooring has a direct impact on the value provided and is therefore the adopted method for assessing floor slipperiness in all conditions.The dedicated project manager worked closely with the contractor during the installation process to ensure highest standards for drainage and protection were achieved. The design, manufacture and installation process was specifically scoped out to meet with all the necessary building regulations in line with the latest HSE and UKSRG guidelines.If you wish to find out more about Aspen Stainless solutions please email: aspen@canalengineering.co.uk or speak to one of our technical sales team via our online chat portal.

There is nothing quite like an ambitious project executed to the highest standard.This complete rebuild and extension of a late Victorian terraced house in Brockley, south east London, presented challenges at every turn. The existing house suffered from the addition of poor-quality extensions and structural problems, but was redesigned by Conibere Philips architects with the specification of Alumasc Rainwater Flushjoint downpipes and hoppers. This ensured elegant and efficient water management, as well as security against water ingress into the new masterpiece of a home.“It’s extremely unusual for a mid-terrace to be demolished and rebuilt in this way, but it was decided as the most economic and sensible course of action to take in this case. This also allowed us to adapt the property on rebuilding to look much more contemporary and elegant,” explained Robin Philips, Partner Director at Conibere Philips. Elegance was also firmly the desired direction when considering water management.“We chose to specify Rainwater Flushjoint downpipes and hoppers from Alumasc to maximise on their sleek and minimal design that would further contribute to the contemporary look of the building,” Robin confirms.“The joints in the RWP sections are very elegant. The whole effect is much less cluttered than most other RWP products. A simple, modern elevation would have been ruined with more traditional RWP products.”

The Royal Albert Hall in the heart of vibrant west London is distinctive for its unique circular architecture and Victorian styling, and famous for bringing a wealth of high-brow art and culture to the city since it opened in 1871.A building such as the Royal Albert Hall is not only a building, but part of the heritage of its surrounding community. For this reason, the Royal Albert Hall Grade One Listed and meaning all proposed renovation works must meet strict regulations put in place to ensure the preservation and respectful enhancement of the building.Sir Robert McAlpine were awarded the overall contract to deliver a programme of upgrade, renovation and refurbishment work. So, when it came to replacing the original water management systems that had been in place since it’s opening, the challenge was on to find a manufacturer and installer that would bring the Hall the best products possible that were also in keeping with these requirements.Gutterworks, an Alumasc approved installer, installed Alumasc Rainwater management systems during the refurbishment in 2018. Alumasc was chosen for its ability to analyse and precisely recreate the original gutter and pipe mouldings that were used in the originally installed systems, therefore contributing to the preservation of the historic building. Over ten years ago, Alumasc Rainwater management systems were installed in a similar project at Kings Cross St Pancras Station.

Heritage Cast Iron Rainwater systems from Alumasc have been used at The Lancasters, one of London’s most exclusive and prestigious residential developments.Overlooking Hyde Park, The Lancasters was originally a parade of 15 magnificent stucco-fronted Grade II listed houses dating from the mid nineteenth century. More recently used as a hotel, it has now been restored and developed into 77 prestige homes. A leading team of developers, architects and interior designers has created a unique fusion of traditional architecture with brand new design and construction.Alumasc’s Heritage Cast Iron system was specified by the architects Nilsson, for its combination of traditional manufacture and modern quality control standards. The result is a highly robust rainwater solution that provides a visually sympathetic finish to fully complement the stunning Victorian architecture.The Heritage Cast Iron was installed by Premier Services Installations (PSI) Ltd and comprised traditional 4” downpipes and ogee gutters finished in a bespoke white, created especially for The Lancasters by Alumasc who created a dedicated paint line to ensure the order was completed on time.Dave Jones of PSI Ltd commented: “The Lancasters is the largest fascia construction project in Europe and boasts one of the longest and highest Victorian residential terraces in the UK. The sheer height of the building required eighteen 1.8m lengths of downpipe from ground level to the hopper heads.

Skyline fascia soffits from architectural rainwater specialists Alumasc, have been used for the extensive refurbishment of The All England Lawn Tennis and Croquet Club in Wimbledon.Driven by the need to enable all-weather play, renovation of the legendary Centre Court included a state-of-the-art retractable roof. From the outset, Alumasc worked closely with Architects Populous of London, on the massive six-year undertaking which resulted in one of Alumasc’s largest rainwater product installations to date. Alumasc’s Skyline soffit system was specified for the underside canopy of the stadium bowl, in order to meet the demanding performance requirements for the arena’s ceiling cladding. 6000 individual soffit modules were supplied, in 80 varying profiles and sizes, totalling an impressive 6500m² of aluminium and associated fittings. Dedication to client support was priority, with Alumasc attending numerous site meetings and manning extra shifts in order to accommodate workload and deadlines. Alumasc’s premium level of technical assistance involved the provision of full product mock-ups prior to manufacture and regular testing of the Skyline system throughout the construction process, to ensure compliance with the client’s requirements at all times.

Set in the heart of the West End, Duke Street is a high end area of commercialised buildings and expensive flats. Some of the listed properties on the street date back as early as the 18th century. Alumasc Rainwater’s range fitted perfectly in this setting. Painted Cast Iron and Heritage Cast Aluminium were specified by Latitude Architects.“The main objective was to provide and produce material as close to the original,” says Alumasc Rainwater. “Bespoke castellated guttering was installed with special curled ear belts to secure the pipes. Together they provided an exact replication of style to the original. We also custom-made guttering that was designed to fit at a specific angle and level of the building.”

The historic Bell Street Stables in Glasgow has recently undergone an extensive conversion, featuring the installation of Alumasc’s Flushjoint aluminium rainwater downpipe system.This magnificent period property has an interesting history. It was built between 1896-98 by A. W. Wheatley, originally to house horses working to pull the Glasgow City Council Cleansing Department’s refuse collection carts. In 1955, the building was redesigned to provide a separate entrance for the Police Department who shared the property with Cleansing until the 1980s. Situated in a prime position within the Merchant City area in the city centre of Glasgow, the building was converted to form 52 mid-market affordable rented flats by the Construction and Manufacturing Group (CCG) on behalf of Glasgow Housing Association (GHA) and Lowther Homes, during a two-year construction programme. The renovation was completed in 2019.A major requirement of the renovation was to conserve as much of the building’s heritage as possible, which included all exterior aspects. This involved the upgrade of the stone elevation, replacing all windows and making repairs to the roof and rainwater system.Flushjoint aluminium downpipes along with contemporary hopper heads were specified for their contemporary design. The installation was completed in a non-standard RAL colour to match and complement the window surrounds. 

Clapham Junction Train Station is one of Europe’s busiest Railway Stations handling up to 50,000 passengers per day. AJ Wells designed, built and installed vitreous enamel cladding for the Grant Road Entrance.Detailed site surveys were carried out to design the appropriate framing system for the cladding panels. There were a number of design requirements to be considered including: provision of a rainwater management system, emergency fire escape, access doors, interfaces with electrical equipment, staircases and uneven flooring.Everything was successfully incorporated, manufactured and installed on-time and within budget in time for the new connection to the Overground to open just before the London Olympics.During installation, careful logistics and passenger safety were our top priority, with much of the works carried out at nights and weekends. Much of our work was carried out alongside other contractors working on floors, ceilings and electrical connections.KEY FEATURES: • Framing system and vitreous enamel cladding • Incorporates rainwater management system • Incorporates emergency fire escapeA.J WELLS SERVICES: • Design, Build & Install Project • Site-Survey, CAD design • Manufacture • Installation of framing system and VE cladding • Provision of project documentation

Magestic match for larch claddingThis larch cladded, timber frame construction sits within a beautiful silver birch woodland site in the north of Scotland. A galvanised rainwater system was selected for the one and a half storey, two bedroom detached house by architect David Dittman. Client, Kevin Grant, says, "Rainline was specified by our architect, however, I have seen it used extensively in the area and was particularly keen to have it myself anyway". Local contractor MacGillivray Construction was used for the build, the rainwater system was purchased through online merchant Roofing Superstore. The client was pleased with the product and submitted the project as an entry to our My Rainline competition. Mr Grant has since built a garage and will be installing a matching Rainline system himself.

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.

A new 4,000m2 staff car park was required for this large brewery in Monmouthshire. Sustainable water management was a key priority for the client. As a result they had specified full infiltration porous construction that would allow rainwater to soak into the pavement, before being slowly released into the ground. This would help to reduce the rapid runoff which can cause local drainage systems to be overloaded after heavy rainfall.The new ULTIPOROUS surface provided a safe, all-weather parking area which would avoid surface water after heavy rainfall and formation of ice during the winter. It also met the client’s sustainability requirements by helping to manage rainwater at source and control its release into the surrounding environment.

Landmark is a 180,000 sq ft prime office development located in Manchester’s premier business district. Partially built off-site, it has been designed to achieve the highest sustainability standards – a BREEAM rating of ‘excellent’ and an Energy Performance Certificate rating of A so the thermal performance of its insulation was hugely important.Building regulations in England and Wales ban the use of combustible materials on all buildings over 18m. With 14 floors and a roof height of 27m, the architect, Squire and Partners, specified non-combustible insulation with Euroclass A1 reaction to fire classification.With this in mind, external wall sub-contractor FK Group consulted the Knauf Insulation Technical Support Team for advice about which insulation to use. The team conducted 3D U-value calculations and determined that Rocksilk® RainScreen Slab in thicknesses of 50mm, 100mm and 150mm would achieve the desired U-value.Rocksilk® RainScreen SlabRocksilk® RainScreen Slab is manufactured from Rock Mineral Wool and has a thermal conductivity of 0.034W/mK. It is BBA certified for use over 18m and has the best possible Euroclass A1 reaction to fire classification, meaning it met the required specification for fire safety.FK Group also sought advice about what to do if the Rocksilk® RainScreen Slab was exposed to rainwater during installation. There is a common misconception that the thermal performance of Mineral Wool will be permanently compromised if it gets wet, but this simply isn’t the case. Rocksilk® RainScreen Slab has been developed for external applications – its fibre matrix promotes water run-off, and it contains moisture-repellent additives in the binder. This ensures it can withstand higher levels of exposure to moisture during installation. Knauf Insulation also provided advice on the storage of insulation on site to protect the insulation from prolonged exposure to rainwater prior to use.Offsite constructionLandmark was built using an offsite construction method. Decorative concrete rainscreen panels were manufactured by Techrete in Hull. Rocksilk® RainScreen Slab was fitted offsite before the entire panel was transported to Manchester and craned into position on the concrete frame.The Knauf Insulation Specification Team provided further support by carrying out visits to both the Techrete manufacturing facility and the construction site to check the insulation was being installed correctly.SustainabilityAs well as its thermal and fire performance, Rocksilk® RainScreen Slab offers considerable sustainability credentials. It is manufactured with ECOSE® Technology, Knauf Insulation's unique bio-based binder that contains no added formaldehyde or phenol. ECOSE® Technology is made from natural raw materials that are rapidly renewable and is 70% less energy-intensive to manufacture than traditional binder, so it is more environmentally-friendly.Products made with ECOSE® Technology are soft to touch and easy to handle. They generate low levels of dust and VOCs and have been awarded the Eurofins Gold Certificate for Indoor Air Comfort. This is beneficial when insulation is being installed offsite in an enclosed industrial environment.Enhancing the St Peter’s Square heritageMurray Levinson partner at Squire and Partners said “Landmark is an important project for Squire & Partners, representing our first completed new build project in Manchester. When we were approached to design Landmark, we recognised an opportunity to extend the cluster of prime office buildings of the adjacent St Peter’s Square southwards. Our design concept aligned itself with the new developments, whilst creating a building which enhanced its specific site heritage and context.“A priority for both ourselves and the client was to create a building with exceptional sustainability and wellbeing credentials, and we are proud to have achieved BREEAM Excellent and EPC A ratings,” added Levinson.Thanks to its thermal performance, fire safety and environmental credentials, Rocksilk® RainScreen Slab will contribute to Landmark achieving the world's foremost environmental assessment method and rating system for buildings. All of which means this will truly be a landmark building both visually and in terms of sustainability.For further information about how our insulation can contribute to BREEAM, see below.https://www.knaufinsulation.co.uk/all-downloads?search=BREEAM

This new build project in the centre of Cambridge combines a Sustainable urban Drainage Solution (SuDS) with vegetation and renewable energy in a warm roof construction.The client for the Department of Civil Engineering at Cambridge University, R H Partnership, identified sustainability as being a key driver in the design of the roof, but also sought a single source supplier that could provide a guarantee for both workmanship and products. Bauder’s systems range encompasses products to meet all the sustainability objectives, and with our network of approved contractors carrying out the installation, we could offer the comprehensive guarantee that was required.Bauder Building BoardProject:Cambridge University Department of Engineering​Location:CambridgeRoof Area:1610m²Client:University of CambridgeSpecifier:RH Partnership ArchitectsMain Contractor:SDC LimitedApproved Contractor:Voland LimitedThe specificationTo meet the sustainability criteria set out by the client, the Bauder technical team designed a roof system combining an extensive blue roof, a green roof and a solar PV array. The first and most fundamental element of the roof system though is the waterproofing. Bauder Total Green Roof System (BTGRS) was selected as it provides robust and durable waterproofing with a life span in excess of 35 years, as validated by BBA Certificate 10/4744. The Plant E cap sheet has also been tested by the FLL to ensure long term root-resistance, making it ideal for use in conjunction with the BauderSOLAR G LIGHT system. The BauderSOLAR G LIGHT system is a unique way to combine rooftop vegetation with renewable solar energy. The PV panel mounting boards are held in position using the growing medium as ballast, meaning the waterproofing is not penetrated and therefore compromised. The mounting boards incorporate a water retention feature which allows a small amount of excess rainwater to be stored for short periods of time for the various plant species to feed from. The BauderSOLAR G LIGHT system’s unique mounting system lifts the panels above the vegetation allowing the plant life to grow freely and therefore qualify a greater area of the roof as biodiverse.In addition to the BauderSOLAR G LIGHT system, a blue roof was added to the build-up. Blue roofs are sustainable drainage solutions designed to manage stormwater on a flat roof to reduce water runoff rates and ease flash flooding and standing water in built up areas. The BauderBLUE Roof System attenuates water from a flat roof over a 24-hour period via a restrictive flow outlet. Calculations are carried out to determine the rate at which the water should egress the rooftop. This is determined by the local planning authority and is often set as low as 5-8 litres per second per hectare. With these calculations, Bauder can design each flow restrictorto meet the necessary runoff rate. For the Department of Civil Engineering, the main roof area of 1455.5m² required two flow restrictors, each with flow control holes to ensure the specified discharge rate of 0.77 litres per second was achieved. The maximum depth of water the roof is designed for is the H-max. When the water level reaches H-max, it will drain via the emergency overflow pipe. These overflow pipes are set at the same height as the H-max level. On this project the H-max was calculated to be 99mm. Although an unlikely scenario, this provision for a ‘once-in-a-hundred-years’ storm event will ensure that the structural integrity of the building is always preserved.Project challengesThe roof deck was constructed using a pretensioned concrete plank roof structure. Due to the large span of these planks, the dead load weight to the roof would be restricted. This being a blue roof with green landscaping and PV (a reasonably heavy build up), presented the issue of balancing the need of the roof design and the weight restriction of the supporting structure. To add to this challenging scenario, the pretensioned deck did not provide a completely flat finish. When installing a blue roof, a flat deck with no positive or negative falls is essential, as detailed in the 2018 update of BS 6229 – Flat roofs with continuously supported flexible waterproof coverings. To overcome this onsite challenge,the final deflection of the fully loaded roof was calculated and the concrete deck was screeded to give a flat finish.The resultBauder believes this project to be one of the first of its type in the UK to bring together so many rooftop systems in one space. Project management and clear communication was paramount in order to ensure a smooth installation. The Bauder project team consisted of green roof and solar PV product managers, area technical manager, technical design team, site technicians and approved installers for the waterproofing.With all the different elements being installed, green roof and solar PV product managers worked with our technical team to design the best possible PV array configuration for optimum energy generation whilst also qualifying for the maximum biodiverse area.Bauder site technicians worked closely with Bauder approved contractors, Voland Asphalte Ltd, to ensure works were kept to schedule and that a high quality of workmanship was maintained throughout.To ensure the landscaping is maintained, irrigation was installed by Access Irrigation Ltd. The system, Permadrip Pro, is a drip line irrigation system with anti-syphon design to resist clogging and pressure regulation. Due to the specialist nature of the irrigation system, Access Irrigation Ltd provided a bespoke design service.The result of this network of expertise was a multi-faceted support service for the client, specifier, main contractor and roofing and PV installers. System installed1 BauderPLANT E 42Green, 5mm torch-on root-resistant capping sheet.2 BauderTEC KSA DUOA self-adhesive, elastomeric, bitumen underlayer. This underlayer was used to ensure thorough sealing of lap joints in low temperatures when the roof was installed.3 BauderPIR FA-TETissue-faced flatboard insulation faced on both sides with aluminium foil to provide efficient thermal output.4 Bauder Super AL-ETorch-on air & vapour control layer. Once installed on the concrete pretensioned plank deck, it can act as a temporary waterproofing layer, allowing internal works to be carried out immediately which was a huge advantage on this new build project.

Halton Borough Council had an easy decision to make in choosing Brett Landscaping to work on a key infrastructure project on the major traffic route. Brett Landscaping offered Halton Borough Council specialist advice before and during installation of their Trief Containment Kerbs at the Kingsway Central Reservation Redevelopment in Widnes. The project was to rebuild and renovate a dual carriageway’s central reservation which featured low-level walls retaining grass verges that were showing signs of damage due to a combination of weathering and rainwater pressure behind the wall.
