Our infill gratings were the perfect choice for this spa setting, allowing a flawless finish of the chosen floor type against the drainage, completing the aesthetic appeal of the room

The second tallest building in the United Kingdom, and tenth largest building in the world is home to an impressive amount of BLÜCHER EuroPipe! All 62 floors are equipped with stainless steel drainage, from RWP, SVP and food vacuum systems to interceptor foul drainage and disconnecting traps for rainwater.The project spanned over two years, and it was a no brainer that our lightweight, adaptable and push fit system was chosen as the sole supplier.

This asbestos cement roof was heavily contaminated with moss and lichen, following many years of neglect. Liquasil's asbestos roof coating, Asbestoseal was specified because it is the only such coating with BBA Approval for asbestos roofs. Also, the completed project came with a 10 year Latent Defects Insurance Guarantee. The roof now repels water instead of absorbing it and nothing can grow on top of the coating system, meaning it will stay moss-free forever. Call 0121 709 5352

The lightwell lift includes caged, enclosed sides to secure the load and prevent the risk of anything falling from the platform onto people below. Interlocked doors were fitted to prevent any accidents whilst the goods lift is in use. Interlocks ensure that the lift will only operate whilst the doors are locked shut, opening again once the lift has travelled to the level required. This provided the team with a safe and efficient lifting solution when moving their big commercial bins from below ground to pavement level. The 500kg capacity allows deliveries to be taken from kerbside to the basement.

The UNIFOLD® Gutter Lining System has recently been installed within five valley gutters, totalling more than 700metres, on the Argos Distribution Centre, Castlegate, Wolverhampton.The facility, operated on behalf of Argos by Wincanton, had experienced severe storm water ingress due to the overwhelming of the existing gutters and outlets, causing severe damage and disruption.The roof had been over-sheeted several years ago and the existing gutters were fitted with a continuous plastics liner at this time.This liner was not lying flat due to expansion and contraction problems, leaving raised areas within the gutter, further reducing the available capacity and contributing to the problems being experienced.Ampteam Limited along with rainwater drainage experts CRM Rainwater Drainage were invited to propose a solution to the problem.Survey and DesignFollowing a survey by Ampteam and CRM, a design solution was provided for the gutters.As the existing gutter had insufficient capacity and any modification to the roof at the eaves position to enlarge the gutter was not an option, the design solution required the use of all of the available space within the eaves cavity.The situation was complicated by the need to control works on the asbestos cement gutters on a building constantly in use. This in turn meant that no extra outlets could be introduced and the existing outlets could not be enlarged.The solution involved the installation of a multi-hinged Unifold gutter, fitted and sealed to the underside of the roof sheet in order to maximise the gutter capacity, combined with specially designed siphonic outlets. As the eaves conditions varied along the gutter runs and within each gutter and access was tight, the UNIFOLD® was supplied with 7no hinges.This facilitated relatively easy installation in very difficult circumstances.Siphonic OutletsThe UNIFOLD® gutter was also provided with factory fabricated side boxes to house the unique siphonic outlets that were designed and tested by Dr Malcolm Wearing of CRM Rainwater Drainage.Although the capacity of the gutters had been increased to the maximum given the existing roof conditions, these siphonic outlets, manufactured and installed by Aquaphonixs Limited, were essential to improve the drainage performance of the existing outlets and to allow the system to function without any additional outlets.Fan shaped, semi-circular siphonic outlets with an offset 100mm diameter tailpipe were specially designed to fit inside the UNIFOLD® side boxes and into the existing 150mm diameter outlets.The siphonic outlet tailpipes were connected to flexible tubes, sleeved into the existing plastic downpipes.The custom made outlets were optimised and tested in laboratory conditions and proved to provide a capacity of over 27litres/second, ten times the capacity of a standard 100mm diameter outlet.Calculations to prove the design solutions of both Unifold gutters and siphonic outlets were provided by CRM Rainwater Drainage.InstallationThe UNIFOLD® gutter system was installed by approved contractors Traditional Structures Limited who, due to the relative complexity of the contract, originally forecast a period of 7 weeks to complete the installation.First class organisation, excellent site personnel and attention to detail by both Traditional Structures and Ampteam Limited meant that the installation was completed in just over 4 weeks with no disruption to processes within the building.

Waterproofing this historic London landmark – external waterproofing with Newton 403 HydroBond, internal waterproofing with Newton System 500, installed by Newton Specialist Basement Contractor MacLennanUK.Newton Waterproofing were delighted to return for this project at the prestigious Houses of Parliament in London, a landmark that has dominated London’s skyline for over 150 years. Newton Specialist Basement Contractor MacLennan Waterproofing was approached to specify a guaranteed waterproofing solution for the new-build basement.After reviewing the technical drawings, MacLennan decided to bring the job to Newton, whose product range was perfectly suited to the project requirements. Newton and MacLennan are both privileged to be the companies chosen to share in securing the future of the Palace of Westminster.This complex project required the design and installation of an external waterproofing system, an internal cavity drain system, and a polyurea roofing system to ensure a high standard of waterproofing.Externally, Newton’s innovative ‘Type A’ 403 HydroBond membrane was applied extensively to ensure the necessary waterproofing around the basement, whilst internally, Newton 508 and Newton 520 membranes were both applied from floor to ceiling as part of Newton’s complete System 500 cavity drainage solution. With the finished structure in place, the waterproofing was finally completed by the application of both a polyurea coating and further drainage membrane to the roof deck of the basement.With a waterproof basement fully compliant with the requirements of BS 8102:2009, coupled with guaranteed protection against water ingress, this newly completed, large basement area, situated directly next to the River Thames, provides a durable and well-established waterproofing solution, utilising multiple Newton Systems to great effect.

The stadium is actually tilted on one side a little bit which makes a lot of significance. The slope is from the north end of the ground to the south end of the ground. And the difference in depth is 2.5 metres.This is where I wanted to arrive:With or without a slope? That's the question. Sometimes, having or not having a slope in a site, can make all the difference for the drainage solution needed. As you know, as slope limitations can be found in some places, but in ULMA we have a solution:The first Polymer Concrete channel with built-in 2.5% slope.

Where do bikes and bins go in slick commercial buildings in space-strapped cities? A big question answered by a Stannah Goodsmaster 1000 CD Plus goods attendant lift in the revamped Kings House office building in central London. The 1000kg through-car lift moves bicycles and a 1100 litre wheelie bin between the ground floor and the basement storage facility in this extensively reconfigured and refurbished building located on King Street.

Brand New Oasis Academy, Silvertown Leads Education Facilities by a Mile with Garden Roof Spaces, and Rooftop Sports Pitch In the heart of what is now the Royal Docklands, a former industrial zone south of Royal Victoria Dock lies a brand new carefully considered Academy. Set to serve 600 students in this emerging community, the “superblock” thrusts modern educational facilities well into the 21st century. Despite the constrained site, the building design harmoniously incorporates vantage points from outdoor social spaces at varying levels.There’s no need to worry about a gravelly all weather pitch causing havoc at your hockey match. There’s a state-of-the-art full size Multi-Use Games Area, lush planted external roof spaces, a double height sports hall, and main hall/performance area making up the core of the building inside.CLIENT BRIEF AND DESIGNRenowned in their field, regeneration experts Morgan Sindall required a single sourced end-to-end roofing solution that could deliver a full system specification underpinned by a 35-year system warranty, installation expertise and site management.Understanding the Architect’s vision at award winning Rivington Street Studio to create a transformative educational haven and maximise the potential of the outdoor roof areas helped the Alumasc Roofing team bring this roof to life.PARTNERSHIPWorking with the project teams across Morgan Sindall, Rivington Street Studio and Fenland Flat Roofing pushing the boundaries and setting the standard for the future of the built environment in the Education sector.Tim Mott, Senior Design Manager, Morgan Sindall, “Brian and the Alumasc team have been on-site with additional safety constraints and delivered high-quality regular progress reporting to achieve the deadlines for the students to move in next year and really put these fantastic facilities to use.”Brian Cottington, New Build Regional Manager - South East & London, “The original specification included warm roof build ups which utilised tapered insulation, however this was subsequently adapted and working closely together with the Architect, Morgan Sindall and Fenland Flat Roofing we implemented a universal standard build up using an inverted system, with less complexity whilst achieving the high system performance and BRoof (t4).”Richard Trew, Associate, Rivington Street Studio, “The garden roof areas and outdoor space bring this building to life and against the industrial backdrop create a nurturing school environment. It was great working with the Alumasc team solving problems and overcoming design challenges along the way.”Chris Preston, Estimator, Fenland Flat Roofing, “Working closely with the local Alumasc Roofing Site Technicians and engaging in extensive discussions agreeing the final system requirements meant the installation process ran smoothly.”ENVIRONMENTALLY FOCUSSED SOLUTIONThe high performance Hydrotech inverted roof is a special formulation of refined asphalts and synthetic rubbers with 30% recycled content.

When it comes to residential, commercial or any structure below ground, waterproofing is a critical component within the construction process for protecting and preserving a building. A poorly designed or installed waterproofing solution can fail leading to significant implications on the structure itself.Delta Registered Installers, Abtech (UK) Ltd were called upon to give assistance on a particularly technically complicated project where approaches to waterproofing design and installation had been incorporated, however the system had failed. For a great remedial waterproofing outcome, seek assistance from an experienced waterproofing company to inspect your site and carry out the remedial work.The property when built had a Type C, cavity drain membrane systems incorporated (not a Delta System), however there was no basement drainage incorporated into the design to manage water ingress.In principle a Type C, drainage system is a water management system. The Type C system is used to control water ingress once it has penetrated the structure.  Moisture or running water travel behind the Type C membrane within a controlled drainage system. A Type C System isn’t classified as a barrier but provides protection by means of water management. For a Type System to be successful a suitable drainage system is required to collect and discharge water ingress to a suitable and safe evacuation point (either by natural forces or a mechanical pump system).When correctly installed, groundwater drainage channels effectively relieve hydrostatic water pressure in the below ground structure. They are installed below flooring membranes at the floor/wall junction.

The Royal Blackburn Hospital, located in Lancashire, England, was dubbed a “ticking time bomb” that could “collapse without warning” due to the failure of its existing reinforced autoclaved aerated concrete (RAAC) roof. This issue was part of a larger nationwide crisis, with 34 NHS buildings, including Blackpool Hospital, and thousands more schools, offices and more at risk of collapse due to the deterioration of RAAC structures. The estimated cost of repairs for these buildings loomed at over £1 billion. In the face of this urgent and challenging situation, The Royal Blackburn Hospital sought a solution to ensure the safety and integrity of its infrastructure.The Royal Blackburn Hospital's existing RAAC roof had reached a critical state of disrepair. The risk of a catastrophic collapse was real and imminent, posing a serious threat to patients, staff, and the hospital's ability to provide essential medical services. The financial burden of repairing or replacing such a roof was substantial, and the hospital needed an innovative, cost-effective, and expedient solution.The hospital administration and engineering team explored various alternatives to address the RAAC roof crisis. After careful evaluation, they opted for Britmet's Tactray 90 Structural Liner System as the best solution to mitigate the risk of a roof collapse. Tactray 90 offered the necessary structural reinforcement while ensuring long-term durability and stability. The installation could be completed with minimal disruption to hospital operations, a critical consideration given the hospital's 24/7 operation.Project Outcomes:Implementing Britmet's Tactray 90 Structural Liner System at The Royal Blackburn Hospital resulted in several significant benefits. The hospital's roof regained its structural integrity, mitigating the risk of collapse. The hospital saved a substantial amount by opting for the Tactray 90 system as it provided a weatherproof roof covering to minimise the impact of construction so that the hospital could resume full medical services quickly, ensuring continuity of patient care. Conclusion: The Royal Blackburn Hospital's adoption of Britmet's Tactray 90 Structural Liner System offered an innovative solution to a critical structural problem caused by the failure of the existing RAAC roof. This case study demonstrates that even in challenging situations involving aged infrastructure, cost-effective and efficient alternatives exist to safeguard structural integrity, ensure safety, and enable the continued provision of vital healthcare services. The success of this project serves as a model for other NHS facilities grappling with similar RAAC-related challenges, providing hope for the resolution of the wider national crisis.

Perry Hall Academy, a large primary school built in 1949, with original waterproofing still in-situ. IKO assisted the Academy funding bid by providing a detailed survey report, including intrusive core sample analysis. The roofs were suffering from water ingress, cracks in the mastic asphalt, pooled water and poor heat retention, so decision was made to replace the roofs throughout. New rooflights were also specified to allow more natural light in while the design chosen reduced the external noise transmission. IKO worked with specifier Concept Education Services to deliver the project (some work during term-time) within 6 months.

Heslington East Campus Student Residences: Sustainable and Efficient Expansion Alongside the preservation of listed buildings, the University of York is investing in a flagship £130m development for students that promotes wellbeing, community, and sustainability. The initial phase sees 16 brand new student accommodation blocks and 2 communal hub buildings providing flexible social spaces. Surrounded by stunning lake views and natural habitats, the buildings are part of a huge initiative to expand the student accommodation offering.GOALSArchitects Sheppard Robson alongside Graham Construction sought to futureproof accommodation by incorporating multi-use buildings, including catering outlets and social hubs. Key to the brief was using the latest in safety, energy efficiency, longevity, and warranty credentials. Graham Construction’s use of modular external sandwich panels, prefabricated steel bathroom pods, and pre-assembled services distribution racks used Modern Methods of Construction with off-site construction techniques.CHALLENGESThe major challenge was to specify a roofing system that could keep up with the pace of the build, given the typical building was constructed from start to finish in circa 14 weeks.The roof deck comprised of precast concrete slabs which facilitated the works programme for speed of construction and consistency in build quality.Alumasc’s challenge was to find not only a waterproofing solution that was able to keep up with such speed of construction but also to meet a truly sustainable life cycle equalling the lifetime of the building.A key consideration in the design was the roofing materials’ thermal properties. To meet the u-value target of 0.15, Alumasc’s XPS Plus insulation was specified, providing a single layer of 175mm, which reduced the height of the overall build-up when compared traditional XPS.SOLUTIONHydrotech 6125 Waterproofing System / Derbigum Hybrid Upstands For over half a century Hydrotech Monolithic Membrane has been successfully used by architects and specifiers, ensuring some of the world’s most prestigious buildings and structures are kept watertight. With no product failures in over 50 years and guaranteed waterproofing integrity for the lifetime of the structure, Hydrotech offers a total life cycle solution for the building.Hydrotech was specified on the main roof areas for this project as it easily meets individual requirements of the buildings. In addition, the system is designed to last the lifetime of the building or structure to which it is applied, giving long-term waterproofing integrity and no future replacement costs.Applied in a hot liquid state to the deck, and including a polyester reinforcement, the bond of Hydrotech MM6125 is 100% absolute. There is no risk of water tracking below the membrane and because it is monolithic, no possibility of lap failure.DERBIGUM WATERPROOFINGDerbigum sustainable roof system was selected for the upstand areas. This hybrid solution was developed to improve the thermal efficiency in all areas to mitigate against cold-bridging with minimal insulant thickness. Derbigum bituminous membranes are high-performance waterproofing systems offering extended warranties and the highest levels of project support. The upstand zones benefited from Derbigum Mineral which is a mineral surfaced composite reinforced membrane.ROOFTOP MANAGEMENT STRATEGYIn addition to the waterproofing solution the buildings benefit from the full Alumasc rooftop management service. This included the design and supply of safety systems, accessories, and over 20 AOV smoke hatches meeting all British and European standards.Specific safe zones were designed by Alumasc Roof-Pro and positioned around all roofs for safe access. Purpose made clips for installing lightning conductor tape without roof penetration were also provided. All rooftop accessories are part of the Alumasc Roofing specification and therefore can be found back-to-back within the Alumasc 35-year system warranty.PROJECT DATACompletion: Autumn 2022 BuildingType: Student Accommodation ProductApplication: Hydrotech & Derbigum waterproofing systems Certification: BBA Approved & European Technical Approval Architect: Sheppard RobsonMain Contractor: Graham ConstructionAlumasc Registered Roofing Contractor: Tandragee Roofing

The Protec System was used to waterproof the domed green roof areas of this striking, sustainable house development which was featured on Chanel 4’s Grand Designs. With an ambitious vision and a tight budget, Robert and Milla Gaukroger set about transforming a dated 1980’s house overlooking Lake Windermere into a state-of-the-art, eco-conscious home. Since the house lay in beautiful hillside surroundings, in order to blend into this setting, the domed roofs of the house were to be covered with a wildflower meadow mix to provide a green roof construction.The SolutionThe Protec System was chosen as a waterproofing membrane for the roofs as it is ideally suited for green roof applications. Lightweight, flexible and highly durable, the system can easily accommodate structural expansion movements and is tough enough to resist root penetration. The Protec system was applied to over 350m2 of domed roof to provide a long-lasting waterproofing membrane.The key reasons why Eastleigh chose Protec are the same reasons that has seen it become one of the fastest growing cold-applied liquid roofing systems in both the new build and refurbishment markets. Combined with the timber cladding to the verticals of the building, the finished aesthetics of the development blended seamlessly with the surrounding areas.A warm roof build-up that can be made waterproof at multiple stages:For larger projects the Protec system can be made temporarily waterproof at two stages prior to the application of the full waterproofing system. The first stage is upon installation of the sealed, aluminium-faced vapour barrier.The second phase follows the reinforcing of the foil-faced insulation board joints with Protec resin and taping mat. This enables a much more controlled approach to the installation with a greatly reduced chance of rain causing disruption and damage during the works.Highly flexible membrane:Regardless of the size of the roof, Protec forms a homegenous membrane, without a single joint or seam and without the need for any expansion joints.RapidCure technology for quick installation:The application of Protec as a liquid, through to the curing process where a solid, tough membrane that can be walked over, takes only 30 – 60 minutes. This enables large sections of the roof to be fully completed in a short space of time.Installing the Roofing SystemsThe Protec System provided waterproofing to all flat roof areas as well as the extensive parapet wall sections. The roof areas were made up of two designs: the Protec Warm Roof System (approx 7,500m2) and Protec applied to concrete as part of an inverted roof design (approx 1,000m2).The roof installation was carried out with a planned, phased approach that was synchronised to the wider construction schedule. For the warm roof areas, the first stage was to fill the troughs of the structural metal roof deck with acoustic insulation infills that will dampen external noise within the leisure centre. Next, the crowns of the deck were primed ready to receive the self-adhesive vapour barrier.The use of a high-performance aluminium vapour barrier not only eliminates the risk of condensation within the roof, but also provides temporary waterproofing protection, which is extremely useful on larger works such as this.The Polyroof RES Insulation boards, which comprised of a two layer system totalling 170mm to achieve a U-Value of 0.14 W/m2K, were bonded using high-performance PU adhesive to the vapour barrier. Following the wind uplift calculations it was determined that mechanical fixings were not required for this application – making for an extremely rapid installation. As you can probably imagine, fixing through 170mm of insulation into the crowns of the metal deck can be a tricky and time-consuming task.A key advantage of using a tongue and groove insulation system is that the finished surface of the roof is smooth and level without any unsightly board steps that can also lead to standing water issues. The insulation board joints were sealed using Protec resin with Polymat Taping Mat 450 which, in addition to providing additional strength to the joints, also creates a temporarily waterproof layer.For the inverted roof sections, Protec was applied directly to the primed concrete/screed surface. The membrane was inspected by Polyroof Technical Services, signed off and then covered with inverted roof components. An interesting fact when using Protec in inverted roof situations is its incredible durability performance – as tested by the BBA, Protec “can provide an effective barrier to the transmission of liquid water and water vapour for the design life of the roof in which it is incorporated”.Monitoring and CompletionThroughout the duration of the contract, Polyroof Technical Services carried out regular site visits that were reported back to Interserve as part of Polyroof’s free-of-charge contract monitoring service. This enabled the client to keep up-to-date with the progress of the roof installation in detail and also provided peace of mind that the original specification was being closely followed and implemented.Polyroof worked closely with the Roofline Group during the installation, enabling the challenges were identified and solved in an efficient and coordinated manner – saving the client time and money.

£75M revamp to Pier 5 at Gatwick airport.

For the new distribution centre at Schiphol Trade Park along the A4, living walls have been realised with MobiPanel, the living wall system from Mobilane. With a total surface spanning 750 m2, the facades of the new distribution centre is greened with the latest generation vertical green from Mobilane.Sustainable and innovative distribution centreA lot of attention has been paid to the appearance of the new distribution centre. With the design of Dedato Architecten, sustainability has not only been taken into account on the inside, but also sustainability at the outside of the building has been taken into consideration by including nature-inclusitivity. Dick Venneman, architect and owner of Dedato Architecten tells: “It is a building with its own characteristic appearance, a landmark from the highway. The building is in its materials friendly and accessible. The different surfaces in the facade gives it a human approach. The living walls and the vertically placed solar panels tells something about the sustainability of the building and plays a role in the preservation of biodiversity in the area”. In addition, the MobiPanel living walls makes the environment more sustainable and improves air quality. The installation of the living walls was carried out by Mobicare in collaboration with Zoontjens Boomprojecten. In addition to the living walls, Zoontjens also installed two large roof gardens with various trees, shrubs and 2,600 MobiRoof ECO sedum cassettes totalling 650 square metres.Distribution centre 2.0 Schiphol Trade ParkThe building spans 30.000 m2 of which 3000 m2 is available for offices. Under the distribution centre, there is a car park spanning 7500 m2 with space for 270 cars. The construction of the new distribution centre began in 2020 and is delivered by Dijkham Bouw BV. “From the environment, wellbeing and to prevent a paved environment, for the design it has been chosen to implement living walls, green roofs and ground level. We are very satisfied about this procedure. The execution is very good, the communication was good”, according to Marcel Smeets – Coordinator at Dijkham Bouw BV. The distribution centre was developed by Minerva Development. Minerva Development is an independent developer with years of experience in the development and realisation of business premises. “Since Schiphol Trade Park has set the goal of becoming one the most sustainable logistics centre, as developers we were very happy to take on the challenge. Next to all other facilities such as solar panels, we have opted for a lot of greenery in the design. Not only on the facades, but also in the surroundings of the building and on the roof. We are very happy with the end result and proud of the fact that because of the living walls, this is by far the most beautiful DC in the area. We are very curious about what the result will be over a few months when everything is in bloom”, Bob Lukassen – Minerva Development.Latest generation vertical greenFor greening the distribution, it was chosen for the new living wall system MobiPanel from Mobilane. MobiPanel is an innovative, sustainable and lightweight system for living walls. It is a modular and circular system consisting of omega profiles and pregrown plant cassettes (40 x 40 cm), provided with an automatic irrigation and drainage system. The plants in the cassettes receive water through capillary action. MobiPanel can be installed on flat or curved walls and is suitable for different types of walls, including certain types of sandwich panels. For the facades of the new distribution centre, sandwich panels from Cladding Point have been used. “With Mobilane, as a global expert with many years of experience, we can continue to lead the way in innovation and sustainability. Cladding Point and Mobilane are ready for the future together”, Frank Janssen – Managing Director at Cladding Point. Cladding Point’s Design+ Carrier sandwich panels contribute to the highest BREEAM category.Client: Minerva DevelopmentArchitect: Dedato ArchitectenConstruction period: 2021Installation: Mobicare

This 6,500m² metal roof at Axcess 10 Business Park, Walsall was soiled, delaminating and affected by spot corrosion in numerous areas, which would have eventually spread and perforated the sheets if a treatment was not applied.Bosworth Cladding Services Ltd ensured that the roof was cleaned and the peeling factory finish was removed with a 4000 psi pressure washer. The laps were ground back and primed as necessary.The whole roof area was then coated with Liquasil's single-coat BBA Certified Metalseal 20 system to provide a 20 year product guarantee upon completion.The completed installation left a metal roof on its way to failure looking brand new, with a protective silicone coating that will last 20 years.For more information, or to make an enquiry, contact Liquasil on 0121 709 5352.

IKOpro Acrylic Roof Coat has been used to provide a quick (taking only 4 days to complete) and seamless waterproof solution to a leaking roof at Bellman’s Auctioneers & Valuers in West Sussex. Contracts Manager for M Holmes Construction (contractor) admits that it was much less labour intensive than traditional roof refurbishments. He said, “The beauty of this system is that you don’t have to re deck the roof, unlike some alternative liquid systems. So this means you save one day of labour, typically four men on a job this size, plus material costs.”
