"roof decking other materials"

WMOR Architects completely redesigned the ground floor to include a flexible living area to open into the garden. Accoya was chosen as the ideal material for the extension because of it aesthetic appearance as well as its ability to provide better insulation than other materials. & the owners wanted to use the most sustainable material they could. The Accoya extension which houses the show piece kitchen will be left to weather naturally and match the pale grey flooring. This was specifically designed so that in the summer, when the sliding door completely opens, the interior & exterior space will merge seamlessly.

Client: Canary Wharf Group Consultant: Adamson Associates Architects Main Contractor: Kilnbridge Construction Ltd Main Products Used: Emseal DFR-2 SystemsWood Wharf Development is certified as a BREEAM Outstanding rated, sustainable mixed-use development that covers a 23-acre site. It consists of 6 individually designed building structures that provide 2 million square feet of curated workspaces and offices, more than 3,500 new residential homes and 500,000 square feet of retail space. The site is being developed as a new 5G and Wi-Fi-6 enabled, London District to include more than 9 acres of interconnected riverside leisure space with boardwalks, squares, and parks to create an oasis of urban green space. The new multistory building structures were designed with 50mm wide structural expansion joints between floor slabs to accommodate the high levels of thermal movement anticipated, as well as the vibrations from traffic and other loadings. These joints also had to minimise any noise transmission through the floors and provide a minimum of 2-hours fire resistance, which is a key reason the consultants selected the Emshield DFR-2 System as it could easily meet all these stringent requirements. In fact the innovative Emshield DFR-2 System can accommodate more than 100% joint movement capability and is CE Marked to EN-1366-4 for up to 4 hrs fire resistance. This unique Emseal solution also has the advantages of not requiring any potentially damaging mechanical fixings into the structure, as it is easily bonded into the joint, with access only required from above. 

Our Clearview range of walk-on balconies have been installed across three floors alongside our Clearview Juliet balconies. A roof terrace also features our balustrade system and our A1 Fire Rated aluminium decking system. Kiran Parmar, Principal Architectural Technician at SGP, was impressed by our contribution, “Neaco offer really good, cost-effective products. They are also very helpful with technical support – they responded quickly in providing key information and design detailing, which was a definite plus point.”

Located at Aberdulais Crescent in Cardiff, each of the twelve properties is a traditionally-built bungalow built fifty five years ago. From the outset, the roofing material utilised on each home was manufactured from metal, although they used standard metal sheeting instead of the advanced metal roof tile Metrotile produces.

Accoya selected for the cladding & decking of the new Forest of Genetic Resource Department, Korea. To date, this project marks the largest wooden scale structure in the whole of Korea. Because of this iconic status the construction had to ensure that the most advanced materials such as Accoya were chosen. Due to the project being 4 storeys high Accoya was selected for its extreme durability & stability. Designed by IDS architects, Accoya was also chosen because of its natural & bespoke aesthetic. Due to Accoya’s light appearance the cladding could be painted to satisfy the designers requirements.

UNIZO office building CHALLENGE Dedalus Architects specified zinc for waterproofing the timber frame UNIZO office building in Eeklo. Not only for the roof, but also for the facade and bottom side of a unique construction detail. To be precise, waterproofing horizontally, vertically and even upside down! To entirely cover the structure however, appeared not to be possible when using zinc. If you opt to use this traditional waterproofing material a ventilated air space must be provided underneath the zinc covering. This of course entails an opening for ventilation purposes underneath the roof edge, if not, condensation will occur. In the case of a building where the facade has to connect seamlessly with the roof and the underside, leaving an opening is not a possibility. So, despite the attractive appearance of zinc, a waterproofing solution with this material was not an option. SOLUTION Thanks to their collaboration with roofer ALBITUM and previous experiences with RENOLIT roofing products, Dedalus Architects came up with a nice alternative: RENOLIT ALKORDESIGN standing seam imitation. A perfect solution for a difficult challenge. No ventilation needed, no connection problems, the same looks as a zinc roof and, above all, more cost effective! 

The flat roof area at above the vast Guernsey Power Station had been suffering from water ingress as a result of failings in the existing EPDM membrane. Due to the expensive machinery housed within and the potential for widespread and costly disruption should the leaking continue.Guernsey Electricity turned to Sarnian Roofing Limited, a Polyroof approved contractor, to provide a rapid and effective waterproofing solution. The Protec System was specified, and work began quickly.The SolutionRemoval of the failed roof coverings to expose the concrete deck below began, and the BBA-approved Protec 20-year system was installed directly to the concrete. Due to its RapidCure technology, the system cures within 30-60 minutes, meaning less disruption for the client.The Protec System provides an flexible and seamless membrane that eliminates the risk of water ingress around penetration points common in industrial unit roofs. As the system is cold applied, there are none of the safety risks associated with the open flames and hot torches used with traditional roll-applied systems.Polyroof’s reputation has been built on the high level of technical support provided to clients before, during and after every contract.We like to work closely with our clients from the very beginning of a flat roofing project right through to completion and throughout the lifespan of the roof. From our experience, this is the best way to guarantee that all aspects of the roof are finished to the superior standards that our clients expect.

A prestigious four-star hotel in Surrey gets a stylish enclosed pergola structure to suit the ambience and scenery of the location. This historic hotel’s large paved terrace area with outdoor BBQ was only equipped with some tables and chairs, and so only used on dry days in the summer months. The hotel's event team wanted to create a new flexible outdoor space that could guarantee availability for bookings throughout the year, whatever the weather....

Roof and facade cover... CHALLENGE For the design of a youth centre a Belgian architect wanted to have a fully homogeneous and waterproof cover for the roof and the facade. This envelope technique needed to be combined with a more ecological and aesthetically pleasing green wall design. SOLUTION For the waterproofing of the roof surface a standard RENOLIT ALKORPLAN roofing membrane was used. For the facades the architects opted for a RENOLIT ALKORSOLAR fixing system as the base to attach the final greenwall system. As the roof and the wall covering (waterproofing) are the same material there were no jointing issues. The whole building has been covered with RENOLIT ALKORPLAN roofing membrane. The facade details were similarly accomplished as standard roof details and RENOLIT ALKORSOLAR profiles were used to fix the rain water pipes from the roof.

This is Liquasil's BBA Approved cut edge corrosion treatment, Flexlap, being installed to a large industrial warehouse in Hemel Hempstead during September and October 2018 as part of a refurbishment project. Flexlap was specified because it is less labour intensive and requires fewer materials than other systems. The unique Liquasiul Latent Defects Guarantee was issued upon completion. This covers materials, workmanship, safe access and Professional Design allowing you to specify with 100% confidence.

The visitor centre roof has been set at 6 degrees to form an exact replica of two spitfire wings. This unique construction meant the need for superior materials, such as Protect 5000 Façade, TF200® and BarriAir, that could cope with the challenges of the design. The materials also needed to be resilient to cope with the harsh coastal conditions in the South of England.

Metrotile is often utilised as a ‘problem solver’ material, chosen when a development needs a new roof that not only requires all of the security and aesthetics a roof should provide, but can also be installed rapidly - this is true of both new-build and refurbishment works. This lead to specification on this exciting Bristol-based office development (more at link)

Comprising of nine shops and several residential flats, properties 29-47 High Street Polegate required a full roof refurbishment after complaints of water ingress into the residential buildings. Proteus Waterproofing conducted a thorough survey which revealed that the existing roof build up, made up of a timber deck and 2-layer felt, had been previously repaired but was now at the end of its serviceable life.Being a residential building with a combustible deck, protecting individual properties from internal fire spread was a key consideration. Compartment walls were identified allowing Proteus Waterproofing to provide a solution that would meet regulatory guidance relating to the junction of compartment walls and roofs in Approved Document B whilst meeting the needs of the client.Proteus Waterproofing specified their robust reinforced bitumen membrane range of Proteus Pro-Felt®, including a bespoke hybrid insulation approach, where instead of a full replacement consisting of entirely non-combustible insulation, a scheme was designed to meet the requirements above and either side of the compartment walls, offering the client the most cost-effective solution possible that would also mitigate any unnecessary increase of weight loading elsewhere on the roof.High Performance WaterproofingThe waterproofing and existing deck were stripped back and re- decked with 18mm plywood. When removing the existing waterproofing, our approved contractor, carefully recorded the exact location of the party walls as no drawings of the upper story flats were available.Proteus Pro-Felt® SA AVCL was used as a vapour control layer to allow for the application of the hybrid combination of 150mm Proteus Pro-Therm PIR insulation and 150mm Proteus Pro-Therm Mineral Wool insulation. A thermal calculation was undertaken to ensure that the final result met the requirements of Part L of the National Building Regulations. These were both adhered with Proteus Pro-Bond Foaming Adhesive. Proteus Pro-Felt® SA Underlay Plain was laid and finished with Proteus Pro-Felt® Ultima Plus Fireguard Mineral Capsheet, providing the client with a fully waterproofed Part B and Part L compliant roof, guaranteed for 20 years.Proteus Waterproofing worked closely with the Proteus Approved Contractor, to ensure the project was delivered to a high standard.Health & SafetyWhen working on occupied buildings, safety is always of utmost importance, as well as keeping disruptions to a minimum. The Proteus Pro-Felt® range have been tested to the highest European Classification of BROOF(t4), making it the ideal system to use on all buildings, as the risks to residents, property and members of the public are greatly reduced. All Proteus Waterproofing specifications promote fire safe installation methods conforming to the industry lead Safe2Torch guidelines. Proteus also have a range of cold liquid applied membranes which are also BROOF(t4) certified.Long Term PerformanceProteus Pro-Felt® offers high-performance bituminous membrane systems, tested to perform in extreme temperatures and weather conditions, while offering clients a robust and cost-effective waterproofing solution. Proteus Pro-Felt® Ultima Plus range retains its high polymer performance.

11 Freebournes RoadBauder reinforced bituminous waterproofing system with BauderSOLAR FSynopsisA large derelict warehouse located in Witham has undergone major renovation to transform it into a storage centre for Essex County Council that will assist its services and benefit the local community. The refurbishment works were designed and project managed by Lambert Smith Hampton on behalf of the client, who wanted the building to act as a benchmark for sustainability with the roof playing an integral part in achieving this through the addition of solar panels.Bauder Building BoardProject Name:11 Freebournes RoadLocation:Witham, EssexRoof Size:5,200m²Client:Essex County CouncilProject Manager:Lambert Smith HamptonApproved Contractor:Acclaim ContractsPV Installer:CJ SolarEnvironmental focus:Solar PVThe specificationWorking closely with the client, Bauder performed a comprehensive roof evaluation survey to identify the full extent of water ingress being experienced and to confirm the suitability of adding solar. The bespoke survey report highlighted that the roof needed to be stripped back to its original deck, before being waterproofed with over 5,200m2 of Bauder’s reinforced bitumen system by Acclaim Contracts. 588 solar PV modules were then fitted onto the roof by electrical installer CJ Solar, enabling the client to generate at least 134.70 Megawatt Hours of solar power each year. Products appliedBauderSOLAR FIntegrated photovoltaic system, where the modules and the substructure are combined to form a single unit, which is secured to the roof without any penetration of the waterproofing or roof deck. System installedReinforced Bitumen Membrane System1 Reinforced bitumen membraneTorch applied, elastomeric bitumen capping sheet2 BauderPIR M 60Rigid urethane foam insulation faced on both sides with aluminium foil.3 BauderPIR FA-TETorch applied air and vapour control layerAdvocacyJulian Sanchez, Commissioning Delivery Manager for Essex County Council: “We actively look for opportunities to implement renewable energy and knew that this storage facility lent itself well to PV retrofit.

Container City is an outstanding example of upcycling architecture in the London Docklands. The buildings are constructed from old shipping containers that have been refurbished and then fixed and welded together, creating an innovative modular building solution that houses offices.The roofs had been waterproofed with an EPDM membrane as part of an inverted roof design, however due to failings within the roof coverings leaks were occurring.It was also felt that the inverted roof insulation was unable to provide satisfactory thermal performance, leading to excessive fuel bills during winter. The architect responsible for finding a solution used Polyroof’s Solution Finder Tool to quickly find a recommendation for improving the thermal properties whilst providing long-term waterproof protection. Equipped with the key information needed, the architect specified the Protec Warm Roof System for the roof refurbishment works.Polyroof Technical Services carried out a full technical survey of the existing roof to identify all existing issues and provide a full set of recommendations. One of the key drivers for the refurbishment was the ability to easily access the roof membrane to carry out regular cleaning and maintenance works, so the specification included for converting the roofs from an inverted roof to a warm roof design.Polyroof Approved Contractor A R Roofing Ltd began by stripping away the old inverted roof components and the failed EPDM membrane to expose the metal roofs of the containers below. A self-adhesive vapour barrier was then laid onto the metal decks and Polyroof RES Insulation (T&G) was bonded on top using PU adhesive. Lastly, the Protec system was laid direct to the insulation boads to create a seamless, smooth and long-lasting finish that came with a 20 year insurance backed guarantee. This striking piece of upcycled architecture now has a roofing solution to match the innovation behind its creation.

Project descriptionDixons Academies Trust is a well-established multi-academy trust that aims to challenge educational and social disadvantage in Yorkshire and the North West.The trust transforms schools into safe and high-performing learning environments, enabling students from all backgrounds to realise their potential and maximise their opportunities after school.Alpha Roofing Systems was brought in to refurbish two roof areas at Dixons Croxteth Academy in Liverpool after the existing waterproofing failed.A number of complex challenges arose from the start; after stripping back the aged and failed single ply system, Alpha identified a water-saturated bituminous roof beneath, which also overlaid the original asphalt waterproofing.The excess weight imposed on the roof from the multiple, heavily saturated waterproofing systems led to cracking and depressions in the deck, as well as rusting of reinforcement within the structure.This meant that, before installation work could even begin, many hours of labour were required to remove the top two waterproofing layers to expose the original asphalt. What’s more, this work had to be undertaken both during term time and a period of heavy rainfall.Solution and installationAfter close consultation with their IKO business manager, Mark Taylor, the Alpha team selected the IKO ULTRA Prevent 25 waterproofing system for this project.To adhere to Department of Education requirements, a 35-year durability statement was necessary, so the long-lasting, durable finish offered by the IKO ULTRA Prevent system was ideal.Challenges continued to come thick and fast throughout the project; after stripping the roof back to the asphalt waterproofing, a large expansion joint was found near the clerestory window. Tapered designs were subsequently adjusted to accommodate.30 tonnes of waste material – primarily due to the uplift of the previous failed waterproofing systems – also had to be removed from the roof over the course of a week.Furthermore, complex design variables meant that Alpha could not fully determine the existing roof falls until the roof had been sufficiently exposed. Working closely with the IKO technical team, design information and solutions were identified to keep the project on track.To complicate matters further, Alpha was also required to carry out this extensive work during active teaching time. This presented not only additional health & safety considerations but also the need to minimise disruption.With a stringent construction phase plan and regular active monitoring, the project was completed with a zero incident/accident rate and excellent feedback from the client on Alpha’s approach to safety.Despite a number of hurdles and complexities to overcome, Alpha Roofing Systems delivered the project ahead of time and within budget, providing a low maintenance, long-lasting roof for Dixons Croxteth Academy and a satisfying outcome for all involved.

Beauty & Heritage - Marley’s Hawkins Fired Sienna clay plain roof tile, the perfect specification choice for a new development in Warwickshire. Properties had to fit seamlessly into the surrounding landscape, while also meeting strict planning regulations. Keith Greenall, MD for Greenall Construction, “The mock Tudor architectural style, incorporating natural materials meant we wanted to find a roofing solution in keeping with the look we had established. “The development required a clay tile perfectly matching the aesthetics within the village & the planning committee were happy the clay material suited the ambience & style of the development & local area.”

To create a Blob... CHALLENGE For the design of a Texaco service station on the highway near Antwerp the architect decided he wanted to create a Blob (Binary large objects) architectural design. The service station consists of three functional lobes that together look like an oil stain. The actual gas stations are covered with 4 lobe-shaped canopies. To accentuate this futuristic design the architect wanted to create liquid formed shapes in a metallic look. As the walls of the main building were planned using a polurea metallic finishing coating the architect sought a suitable compatible material to finish the rest of his Blob roof surfaces. SOLUTION Synthetic roofing membranes are the most flexible materials on the market and are suited to waterproof almost all possible roof shapes. For this particular project the silver coloured RENOLIT ALKORPLAN membrane was the best solution. This silver membrane is produced with a protective coating creating a roofing membrane that is easy to clean. The RENOLIT ALKORPLAN Metallic membranes combine excellent durability with added aesthetical appearance.

Union Wharf is a two tower residential development in Greenwich, London. A 23-storey Roof garden makes the most of the breath-taking views of the London skyline.Designing and specifying products for a 23-storey high terrace comes with some key issues which must be addressed. One of which, the Terrafina decking overcame due to its easy clip system making it a doddle to install and overcome this problem.Another, was to ensure a solid base for the artificial grass and planters to be fixed to. This was however, something Raaft had planned for and the Floor structure panels was an easy solution to this.

Metrotile has often stated that their Lightweight Steel Roofing systems can go head to head with ‘traditional’ materials aesthetically, and Gorse Hill School is a fine example of this statement in action.Gorse Hill is unique as it required a partial refurbishment. Some, but not all of the blocks roofs where in urgent need of repair. For these roofs, Metrotile’s classic ‘Roman’ profile was specificied as its contoured design matched the concrete Roman tiles that remained on some of the buildings.The finished product, is a fine example of old meeting new with brilliant results. Another important factor involved with the specification of Metrotile was the need for a secure roofing solution.

Metrotile Lightweight Steel Roofing now adorns the rooftop of the Bryn Bach Country Park visitor centre near Tredegar, South Wales. Installed to replace the previous leaking so-called ‘traditional’ material roof, that was allowing water ingress in the cafeteria area, the new Metrotile roof has given the facility a new lease of life and an attractive makeover, in time for the busy summer season. Some 2,600 of Metrotile’s vandal proof Slate 900 profile, each covering almost half a square metre but weighing just 4.6kg, now cover the 1,300 square metres roof of the visitor centre.

Daventry International Rail Freight Terminal (DIRFT) is a rail-road intermodal freight terminal with an associated warehousing estate in Northamptonshire. Owned by Prologis, the business park was originally built in the 90’s, but a recent expansion has added around 4 million square feet of storage and office space. Some buildings are already occupied by leading brands such as Royal Mail, BooHoo, Dunelm, Tesco and Sainsburys.DIRFT’s Unit DC628 (DC10) is a net zero carbon building with 627,707 square foot warehouse space rated BREEAM Excellent. Among its features are solar PV systems, a roof terrace, and enhanced external amenities.Our team was commissioned to provide seating and planting solutions for the outdoor amenity space and roof terrace by BCA Design, Landscape Architects for the project.Our RailRoad modular seating solution with Delta supports, and FSC iroko timber slats, that are left untreated to allow natural weathering, was installed in the outdoor amenity area adjacent to the car park - along with Parallel picnic tables and benches and Zenith 500 litter bins - creating an outdoor lunch break environment in which employees can enjoy during warm weather.Decking supplied by Outdoor Deck was installed on the roof terrace of the building, complete with our AKRI 300 steel planters with 500mm high panels, manufactured from triple process recycled steel, to form a variety of linear shapes filled with plants and greenery to create a peaceful oasis with a view of the countryside.Seating and benches made from FSC Iroko timber which included armrests on some, were integrated onto the planters to provide warehouse staff with quiet spaces to relax. The rooftop planters were complemented by the addition of our Hollo range of freestanding low seating / tables

The meticulous refurbishment of this Grade II Listed landmark provides a stunning range of luxuriously specified apartments. Buzon UK were specified to install the PB pedestal system to support two large (220sqm and 180sqm) hardwood decked outdoor terrace areas. This project was particularly challenging due to the many curved planters, upstands, steps and seating areas but the PB pedestal range can be adjusted from 28 to 965mm to create different height levels and the ergonomic design makes it easy for accurate and effective installation. The finished private roof terraces provide residents with the perfect outdoor space.

When The Oval cricket ground recently underwent a major extension, Bostik was on hand to provide subfloor preparation products and technical advice to ensure the flooring couldbe installed to the highest possible standard in time fora high-profile event.The iconic south-London venue is home to Surrey County Cricket Club and frequently hosts international matches and tournaments. The Oval was seeking to add two new upper-tier decks that would increase its capacity by 4,000 seats, as well as a new hospitality area including lounges, a roof terrace,a retail space, a new ticket office and more.

Driftwood is a 5 bedroom home set in a spectacular location. Yunnie Gillespie Architects have used a number a materials that respect the location. This includes the QUARTZ-ZINC PLUS STRAT standing seam roofs and facades.

Moreland Primary School is a purpose built school, nursery and Children's Centre requiring a multipurpose usable outdoor space. Due to lack of space, the ground attenuation tanks planned would reduce site storage and limit access to other trades, therefore delaying the project, The challenge was to develop a storage/discharge system which wouldn't impact the project and be sensitive to the local biodiversity action plan. ABG designed a versatile Blue Roof System removing the need for attenuation tanks and allowing the roof finishes required. ABG bio-diverse roof system helped maximise the BREEAM credits laid out in the action plan

Manchester’s iconic Midland Hotel sits in the heart of the city centre and has been a well-loved retreat for visitors since opening its doors in 1903. Following decades of service to the city, the hotel had started to show signs of its age, with multiple areas of water ingress across the site that needed to be addressed, to preserve the building for years to come. It was essential for the hotel to remain fully operational during the roofing refurbishment, with minimal disruption to its customers.The original single-ply system had failed across the courtyard and atrium roofs, leading to the insulation becoming fully saturated with water. The metal deck’s structural integrity had also been compromised and a structural engineer was appointed to review the extent of the damage, to confirm the area as condemned and in need of immediate replacement.A bespoke Garland UK specification was designed to upgrade the insulation and U-Value of the hotel to comply with current regulations, remove ponding water on the roof systems with a new tapered insulation design and provide peace of mind to the building owners with a 25-year Garland Single-Point Guarantee.

Northampton-based building specialists Linden Heritage specialise in the external and internal renovation of Period and Listed buildings, just part of a wide-reaching portfolio that includes feature both New Build and Refurbishment projects.As period properties can be a stringently traditional arena when it comes to the choice of building materials used (due to strict planning requirements), it may come as a surprise to note that Linden Heritage are proud users of Metrotile Lightweight Roofing Systems – a material that prides itself on being an evolution of the very ‘traditional’ materials required by listed buildings.

A complete roof refurbishment, including thermal upgrade and full waterproofing of a church centre.Systems in useEcoflex®The project included various roof areas with different systems in situ, all requiring thermal upgrade, and increased falls to remove standing water from the roof. There were also rooflights and roof lanterns that needed to either be replaced or removed and boarded over, a live gas pipe which required lifting to accommodate the new roofing system, and various redundant SVP’s and chimneys.ChallengesThree separate roof areas required upgrading as the existing waterproofing was failing and reaching the end of its service life. Water ingress was occurring, causing damage to the internals of the building.Axter carried out in depth surveys and took various core samples to determine the existing build ups of each roof area. It was identified that remedial works were needed to stop water ingress, thermally upgrade the roof, remove standing water, and remove certain rooflights. Two out of the three areas had redundant and dated rooflights / roof lanterns. There was also an active gas pipe laid across the main roof area which had to be taken into consideration when specifying works.SolutionsThe 3 existing roof build ups included Asphalt with RBM cap sheet and stone chippings, Asphalt with RBM cap sheet and solar reflective paint and finally an EPDM system. Our core samples revealed that the areas with existing asphalt were in good condition. Therefore, Axter advised to only remove the solar reflective paint and the stone chippings to avoid the asphalt from going into landfill and to keep costs down. We used a mixture of torch applied and self-adhered AVCL’s, dependant on the deck type and to comply with SAFE2TORCH areas. Axter’s Ecoflex® ADH single ply membrane was the system of choice as this kept the use of naked flames to a minimum as the building remained in use throughout the refurbishment programme. The system provided a 20 Year Guarantee covering design, materials and workmanship and achieves Broof(T4) fire certification.A live gas pipe was running across the main roof area. It was decided with the client that this would be replaced and raised to accommodate the new roofing system.As this was a live site, the safety of the client and their visitors was a risk that needed to be considered. Risk and method statements were developed and written with the client’s ongoing activities in mind. The contract was carried out without the occurrence of any accidents or incidents.AcknowledgmentsWe were delighted to have Axter and the Nautilus work on our roofing project and again were delighted with the outcomes. From initial consultations with both Nautilus and Axter we found them to be highly knowledgeable and professional in providing solutions and specifications. Axter’s attention to detail manifested through their survey work and their recommendations provided us with a great deal of assurance in the project, along with ongoing technical assistance from the Axter team to provide reassurance at different junctions in the project. Nautilus were extremely professional in their approach and a pleasure to have on site. Their high regard for health and safety and CDM on site was also evident and ensured a safe environment for all stakeholders. The project was completed by Nautilus in a timely manner and certified by Axter, giving us high confidence in the completed works. A real pleasure to work with on all sides.Andy Lee , Vine Christian Centre

Rather than using modern interlocking tiles, Wienerberger’s Alban Sussex Blend tiles were used to create the roof and walls of Kingsdown House. The versatility of the Alban Sussex Blend tile was highlighted: the tiles blend beautiful design with a stunning aesthetic result. The tiles were chosen because they enabled the architect to use a single material for the roof and walls, creating a simple, attractive façade that complements its neighbours .

Fosroc contacted the designers of the Victoria Dock project in early 2013. Working with the design team Fosroc UK used its highly experienced sales and technical staff to produce a waterproofing solution using Supercast PVC waterstop and Supercast SW hydrophilic waterbar. Materials including special angles were hand made at our Tamworth manufacturing plant and passed the scrutiny of the Crossrail approvals team. To ensure watertight construction Fosroc provided on-site training on product installation. Materials used on C340 have since been passed for use on other rail projects.

The Gatehouse in Whaddon, Milton Keynes required a complete roof renewal with a new roof lantern installation. Over the years, the roofs had undergone several failed repairs, therefore, the client required a robust, cold applied, cost effective solution. Proteus Waterproofing specified Proteus Pro-Cold® as it's a single pack, fully reinforced polyurethane system that is cold applied, seamless and elastomeric, providing up to 20 years further life to the structures it is applied to.High Performance WaterproofingThe existing roof was a EPDM roof that had to be completely stripped. The deck was replaced and a complete warm roof build up, including Proteus Pro- Therm PIR insulation boards, was installed and finished with Proteus Pro-Cold®. As ponding was an issue on this roof, a new gutter was created to solve this problem. The client was incredibly pleased with the finish, so much so, that their neighbours have requested our Proteus Approved Contractor to carries out their roofing works. Health & SafetyAs the building is an occupied residential building, keeping the residents safe was paramount. As Proteus Pro-Cold® is cold applied, it met all the health and safety criteria, as well as keeping disruptions to a minimum.Long Term PerformanceProteus Pro-Cold® offers a low maintenance, durable waterproofing and protection solution for a range of new build and refurbishment applications.
