"hot and cold water"

A new and vibrant housing development in Chelmsford, Essex recently specified a range of bespoke Skyline solutions where ‘inspirational architecture’ is a key element.Beaulieu Park is a charming new district set around New Hall School, which was originally King Henry VIII’s Tudor palace and estate parkland. The concept behind the development was to create a series of individually designed neighbourhoods, which connect to the wider landscape. “This was an exciting project to get involved with as it was an open specification. This also meant that it was important to get this project absolutely correct commercially,” says John Hemphill, Skyline Technical Sales Manager at Alumasc. “Our work at Beaulieu Park, in conjunction with our customer, involved designing and manufacturing a full and comprehensive range of bespoke Skyline aluminium products such as window pods, copings, canopies, fascia and architectural feature cladding and corner post details.”For this unique project, Skyline collaborated with our ‘Recommended Installer’ Specialised Fixings to deliver and design products that were tailored to each individual house type and plot.

As part of a major transformation of Wembley Park, which includes Olympic Way, Wade Stainless Steel Linear Channels and Streamline, and perforated gratings were installed beneath the Olympic Steps to provide an effective and long-lasting drainage solution.Built by developer Quintain in a joint project with Brent Council, the Olympic Steps come at the end of Olympic Way—the stretch of road linking Wembley underground station to Wembley Stadium. It was named Olympic Way after it was originally constructed for the 1948 London Olympics.The final stages of this redevelopment were the iconic steps that lead up to the national stadium. The original ramp, known as the pedway, was built as part of the old Wembley Stadium and acted as a bridge over the old coach parks. The Olympic Steps development replaced the outdated, concrete pedway and extended the Olympic Way, increasing the width by 50% and improving accessibility for all visitors in and around Wembley Park. Volker Fitzpatrick was the main contractor on the project.“Working closely with Mick Hawkins, the Site Manager, the aim of the project was to fulfil the client’s drainage requirements to tight deadlines,” says Brian Holden-Earl, Area Sales Manager. “The area is frequently used by visitors, so it was important to deliver our services within a specific timescale.”

This dwelling is located in a unique natural environment in the French Pyrenees (Gaillagos, France). When designing this family home, the main focus of the owners was to reduce their energy consumption without giving up to an elegant slate roof. That is why they decided to get THERMOSLATE installed: it is a completely invisible solar roof that gets repaid from day one. Only 4 collectors installed on a total surface of 5m2 were enough to cover more than 60% of their hot water needs (250 liters per day).

The conversion of a traditional barn within the conservation area surrounding Wells Cathedral, Somerset has benefitted from the installation of THERMOSLATE roof solar collectors. The new solar system will generate 57% of the occupants’ hot water requirements. Paul Kellet, the architect, said: “My client was keen to use a natural material for the roof of the property, whilst also making a sustainable contribution to meeting the family’s energy needs. The specification of THERMOSLATE and complementary CUPA R12 spanish slate allowed Paul to meet these requirements.

Bainland Holiday Park, located in Bainland Country Park, were looking for a washroom refresh and specified Franke products for the project. Inspired Washrooms, a Nottingham based fit-out company, executed the project with the installation of a wide range of Franke products including Miranit washbasins and accessories from the Rodan range.The full range of products provided was:4 x ANMW411 - Single Quadro Miranit Washbasins with tap hole4 x F3SV1001 - F3 self-closing taps2 x UC07-010 - Urinal Control Systems2 x UC00-001 - Air Brake (Back Flow Preventer)5 x WC03-002 - WC Flush valve Kits & Wave on Sensors5 x WC02-011 - Concealed Plastic Cistern Kits2 x DRYX500N - Hands in hand dryers1 x F1393 - Franke Airblast Hand dryer4 x CHRX669 - Stainless steel mini jumbo toilet roll holders3 x RODX618 - Stainless steel rodan soap dispensers3 x RODX625 - Rodan Electronic Soap Dispensers  

A Sealwall Tank manufactured by Whites Concrete has become part of Rampton Hospital’s new Energy Centre in Nottinghamshire, which is operated and maintained under a Carbon Energy Fund framework contract. Part of the new Energy Centre that provides heating, hot water and electricity to the Nottinghamshire Healthcare NHS Trust Hospital, Whites Concrete’s pre-cast concrete Sealwall Tank is a component of Rampton’s new effluent treatment plant—now a modern, automated system that meets both current environmental standards and future expansion of the site.

At the beginning of 2016, they started a major refurbishment of their head office. With around 700 employees, they were facing an issue how to meet the demand for hot and chilled filtered water across the three floors. A cause of staff frustration can be the inability to get a drink when they want it, and through the unique energy efficiency technology, the Billi Quadra range provides the solution. Following discussions and a site visit, based on the Billi recommendation, mothercare selected the very popular Quadra 460XL boiling and chilled system in chrome with matching drainage font.

Alumasc Rooflights provided an ideal solution to allowing natural daylight into the building from above. The unique kerb design incorporates both security and waterproofing to create a reliable, safe and secure rooflight, allowing horizontal termination of the waterproof membrane. This makes water penetration virtually impossible. The domed glazing is moulded from Marlon FSX Longlife, premium quality solid polycarbonate, which has an impact resistance up to 200 times that of glass.Technically sophisticated, Harmer AV high-performance aluminium roof outlets are chosen for this project as they guarantee a trouble-free performance and are especially suited to flat roofing applications featuring continuous membranes.Harmer AV roof outlets combine innovative product design with full industry compliance to meet the needs of rainwater drainage in any construction project, with the ability to drain up to 40% more roof area than conventional gravity outlets. Further to this, their lightweight, durable, non-corrodible design means that they will do so for up to 40 years.GX Pressed Aluminium Gutters are robust box section gutters designed for traditional wet jointing on site. They’re especially suited to applications where maximum capacity gutters are required. For the very large drainage area of the campus roof, they were perfect.Designed to fully accommodate thermal movement at every joint, they are lightweight, durable and noncorrodible, and, upholding the environmental prerequisites of this project, they are 100% recyclable.Finally, Heritage Circular Pipes are available in 4 pipe diameters and 3 pipe lengths, together with a complete range of fittings. Can be factory finished to replicate cast iron or with BBA certificated powder coatings in a range of colours.

The demand for an energy-efficient hot water distribution system was met by a single-pipe system with 850m of RAYCHEM HWAT-R self-regulating heating cables, managed by nine RAYCHEM HWAT-ECO smart controllers that interface seamlessly with the BMS. Eliminating the need for the secondary pipework of a conventional recirculation system saved space and achieved cost savings of between five and ten percent in material and installation time. Pipe freeze protection was also provided by RAYCHEM WinterGard self-regulating cables, supported by an AT-TS-13 surface-sensing electronic thermostat.

When Booking.com decided to move their offices to a prime location in Central London, they required a full fit-out. They appointed HLW International, who specified Billi Taps for their main kitchen area, and another tea-point within the office space. Booking.com opted for Billi Quadra Plus 15. With a drainage font in chrome and a gloss finish, the tap delivers instant boiling and chilled water from an XL lever tap at just a touch of a finger, and hot and ambient from a second sink mixer tap – all this from a single under counter boiler unit.

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.

Design consultants AECOM delivered efficient hot water distribution using 800m of RAYCHEM HWAT-M self-regulating cables, to provide a single-pipe system throughout the building. Its compact design, eliminated the need for recirculation pipes, thus enabling the system to be installed in restricted spaces. Pipe freeze protection was achieved using 300m of RAYCHEM WinterGard self-regulating cables. Snow and ice prevention on the car park access ramp was provided by 1200 metres of RAYCHEM EM2-XR selfregulating cable controlled by a VIA-DU-20 multi-sensor control unit.

Single-pipe hot water distribution systems were designed for the new acute inpatient hospital in Wakefield and new diagnostic and treatment centre in Pontefract. 25km of RAYCHEM HWAT-M self-regulating heating cables was used, supported by RAYCHEM HWAT-ECO controllers. The single-pipe design and simplicity of the RAYCHEM installation dramatically eased the modular fabrication process. Fully traced and insulated pipe modules were assembled off-site and delivered to meet strict schedules for connection. Pipe freeze protection for external pipework was provided by some 10 km of RAYCHEM WinterGard self-regulating cables.

A single-pipe hot water system based has been installed with 1.2km of RAYCHEM HWAT-R self-regulating heating system supported by 13 RAYCHEM HWAT-ECO controllers. As the system uses half the pipework of a conventional recirculation system, on-site installation time was cut dramatically and this was enhanced further by use of the RayClic connection systems. It also meant that space savings could be made in walls and ceiling voids. The system is low-maintenance, a critical factor due to the sensitive nature of this building and can now be very easily extended during further planned developments.

Architects Morgan Sindall was charged with creating a state-of-the art, energy efficient building including the hot water distribution system. A specific requirement was for the system to be able to raise temperatures monthly, for the prevention of legionella. A single-pipe solution was designed, using 1.8km of nVent RAYCHEM HWAT-R self-regulating cables to maintain 60°C. Supported by 15 nVent RAYCHEM HWAT-ECO smart controllers, the necessary legionella prevention cycles could be met, pipe temperatures could be varied (to provide setback temperature savings) and thermal boosts to 65°C implemented during times of non-occupancy.

M&E contractor ‘The All Group’ designed 2.5km RAYCHEM of HWAT-M self-regulating cables in a single pipe hot water system throughout the hotel. Controlled by RAYCHEM HWAT-ECO smart controllers, the system provided the benefits of energy efficiency plus savings in material costs, labour and space. Pipe freeze protection was delivered using 5.5 km of RAYCHEM WinterGard, controlled with RAYCHEM RAYSTAT-ECO-10. Underfloor heating was installed in the bedrooms, using RAYCHEM T2Red with T2Reflecta. In addition, RAYCHEM T2Quicknet 160 was installed in the en-suite bathrooms and the hotel’s luxurious spa.

3 x high-rise tower blocks in Essex received new ground source heat pumps, 3 x more energy-efficient than their old night storage heaters, reducing heating and hot water bills by up to 66%.Award-winning project:Winner of ‘Regional Large Scale Project of the Year’ at The South East Energy Efficiency Awards 2023Winner of ‘National Renewable Heat Project of the Year’ at The National Energy Efficiency Awards 2023Winner of ‘Climate Action – Decarbonisation / Retrofit Award’ at the Essex Housing Awards 2023Shortlisted for ‘Domestic Installation of the Year’ at the PHAM Energy Saving Awards

To provide high quality instantaneous hot water, the developers were persuaded to move away from a conventional recirculation system to the higher efficiency single-pipe solution, using nVent RAYCHEM HWAT-M self regulating cable and the unique nVent RAYCHEM RayClic connection system. In addition, nVent RAYCHEM T2Red and T2Reflecta underfloor heating was used in the main living areas. The self-regulating cable could provide very responsive heating without overheating, thus avoiding damage to the high quality wooden flooring. Underfloor heating was also used in the bathrooms, using nVent RAYCHEM T2Quicknet. All fully integrated with the BMS to avoid individual controllers.

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.

Harmer Drainage high performance Roof Outlets and SML above ground drainage were recently specified for a new, forward thinking children’s hospital in Liverpool.The Alder Hey Children’s Health Park is a large £250m project developed to improve the paediatric medical facility and enhance the experience of both patients and staff. The aim is to set the hospital as a new benchmark for the delivery of paediatric care in the UK and around the world. It includes six wards, a large critical care unit, 16 theatres and a host of clinical services, together with shops and cafes.

Arras Way is a development of 47 units of 17 houses and two blocks of flats built in a traditional style to create a modern and comfortable living experience. The landscaped communal gardens help maintain the feeling of community life this fantastic location offers. It is situated in the coastal town centre of Folkestone, under 20 minutes to Dover and 35 minutes to Calais via the Euro tunnel. Cellecta’s TETRiS was specified by Apex Architecture as it provides outstanding thermal and structural performance. It produces a floor with zero cold bridges and is quicker and easier to install than a concrete block floor. TETRiS is a foil-facing insulation block with excellent thermal performance and very low water absorption; these blocks make the ideal flooring system.Dwyer Engineering was awarded this 2,914m² contract to construct this development in Folkestone. 

Family houses renovated... CHALLENGE 134 single family houses needed to be renovated to liveable conditions. The main problem for the architect and building contractors was the fact these houses had to remain occupied during the works. SOLUTION For the roof two prefabricated timber roof elements covered with the RENOLIT ALKORDESIGN roofing system were installed to replace the existing roof structure. The roofing elements consisted of a layer of OSB, a layer of 350 mm cellulose fibre insulation, another OSB plate and a 2 mm thick RENOLIT ALKORPLAN roofing membrane. The prefabricated roof element has a U-Value of 0.11 W/m². On top of the prefab roof elements hot water panels were installed. 

Groupe Atlantic’s mission is to help society rise to the challenge of reducing energy consumption and increasing the use of renewable energy whilst still satisfying the demand for thermal comfort. So when RFD Interior Architecture was asked to design and build the interiors for its new Expert Training Academy in East Yorkshire, where the heating and hot water industry could learn about the next generation of renewable energy sourced appliances, it was key that the academy’s interior should itself have minimal impact.With this in mind, the project focused on mirroring Groupe Atlantic’s commercial approach by using sustainable materials and recycled products wherever possible to provide a practical, low maintenance interior with authentic natural aesthetics.

THE PROJECTFulwith Mill in Harrogate is located in an exclusive upmarket area – so much in fact, in 2019 Fulwith Mill Lane was named by Zoopla as the most expensive road in Yorkshire. For this new build project, Fosroc were asked to specify suitable products for the waterproofing aspect of the basement construction. The main challenges included a high water table, high clay concentration in surrounding area leading to a perched water table, and potential for hydrostatic pressure against the basement construction. Howard Civil Engineering was the main contractor for the project, with Fosroc being selected as materials supplier due to a long standing relationship between the companies, and a number of previous deployments.THE SOLUTIONFully bonded Proofex Engage membrane was used on the basement slab, combined with Supercast Watertight Concrete Powder (WCP) to provide a high level of resilience to both water ingress and potential defects. Supercast WCP is a concrete admixture that reduces porosity and permeability, increasing water and corrosion resistance. The vertical elements were cast in Supercast WCP with Proofex 3000, to provide a greater degree of flexibility to enable the contractor to install effectively in the tight spaces around the site, and around the complex shape of the structure. Proofex 3000 is a cold applied, highly flexible waterproof membrane – ideal for application of membrane around intricate building features.THE BENEFITSThe products specified for this project provided multi-layered and seamless protection to the underground element of this exclusive residence to meet stringent BS8102 Type A waterproofing standards. Proofex Engage provides water, water-vapour and gas protection to water excluding structures such as basements, and protects concrete from aggressive ground salts, chemicals and hydrocarbons. It is supplied with a self-adhesive strip on one side of the roll to provide sealed laps and comes with a range of auxillary products (for this project, Supercast SW20 Hydrophillic Waterstop) to form a complete waterproofing solution and simplify application for the contractor. Its unique mesh system bonds permanently to concrete, remaining in pace even if settlement takes place – the exceptionally high bond strength of Proofex Engage - 2.96kN, sets it apart from the competition, at 70% stronger than the leading chemically bonded membrane.

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 PROJECTThe village of Comrie is located towards the western edge of the Perth & Kinross Council area, approximately 40 kilometres west of Perth in Scotland. The waterproofing system used to cover the buried water tank at Comrie Distribution Service Reservoir (DSR) was many years old and had failed. As part of the ongoing Scottish Water SR21 framework, Fosroc and The Fraser Bruce Group have developed a wide range of solutions for waterproofing water tanks that have been proposed and agreed by both Morrison Construction and Scottish Water. This project involved removing the soil overburden and the existing waterproofing system, before mechanically preparing the deck and applying sheet membrane.THE SOLUTIONOnce the overburden and existing waterproofing were removed it was apparent that there was severe ponding on the tank roof. The decision was taken to prepare the deck and apply an external self-leveler to prevent the ponding of water. The perimeter and upstand detailing was carried out before Fosroc’s self-adhesive sheet membrane Proofex 3000 was applied to the primed, horizontal surface. The surface was then protected with Proofex Sheetdrain 80, a drainage and protection membrane. After the membrane was laid, the access hatch upstands received two coats of Nitocote CM210 before more Proofex 3000 was applied and terminated just below the height of the new overburden. The access hatches were then sealed in place with Nitoseal MS600.THE BENEFITSProofex 3000 membrane, which is cold applied and comes in 1m x 20m rolls, is self-adhesive, thereby reducing the amount of product and application time. The applicator was able to cover large areas in far less time. The membrane is made from cross laminated HDPE film to protect against damage, while still being sufficiently flexible for detailing around corners. It is resistant to ground water, soluble sulfates and chlorides, offering robust protection from aggressive ground salts. Its use with Sheetdrain achieved a high quality, reliable installation compliant with EN 13707:2004. By combining the use of Nitocote CM210 and Proofex 3000, Fosroc were able to provide solutions for both exposed and buried areas of the tank with no compatibility issues between the products.

As with all balcony constructions, the issue of cold-bridging (also known as thermal-bridging) must be addressed and minimised to meet the required building standards - Part L of the Building regulations being of particular relevance. The H-BAU ISOPRO® thermal insulation element from J&P solved this problem by providing structural connection between the internal concrete floor slab, and the external concrete (insitu, or precast) balcony, whilst creating a thermal break to minimise cold-bridging.

The waiting room at Houton Pier on The Mainland of the Orkney Islands was cold and draughty due to a weather-damaged door opening directly into the waiting area. An extension was built to create a weather break and fitted with record FTA 20 automatic folding doors which minimise the time the door is open to the elements but still provides good access. The doors are activated by a radar presence sensor for two way traffic. The old door was also replaced with a THERMCORD sliding door with energy efficient core panels to further reduce the ingress of cold air.

Myatts Field North is a major regeneration project in the London borough of Lambeth, the development consists of 808 new homes, and 172 refurbished properties with 10 per cent fully accessible to wheelchairs. New streets, green spaces, play areas, landscaped park with two seven-a-side football pitches, multi-use games area and a play area, community centre, local store, commercial units, and an energy plant which provides reliable and efficient heating and hot water were also installed.Cellecta’s ScreedBoard 28 was specified by PRP Architects due to its ultimate single layer acoustic overlay treatment. It is frequently reviewed as the solution of choice for new build and refurbishment developments. Its high density and unique resilient layer provides an unrivalled acoustic performance.Regenter Ltd was awarded this 50,000m² contract to construct this regeneration in South London.

Emma House, Romford, a residential apartment block built in 2007, needed a new waterproof membrane for the entire roof area after the single ply membrane, installed just 10 years earlier, had failed. The specification by our clients asked for a cold applied system to be used during the refurbishment to minimise disruption to residents, while providing a permanent waterproofing solution.The ChallengeCore samples taken of the roof build-up showed there had been extensive water penetration which required urgent remedial action. Impossible to repair, the complete roof system had to be stripped back to the roof deck by Proteus Waterproofing’s approved contractor. The approved contractor installed a new Proteus Pro-System® BUR (built up roof system) incorporating Proteus Pro-Therm insulation, to provide a new seamless roof – an area of some 150 square metres – offering a 20 year guarantee.Why Proteus Pro-System® was specifiedProteus Pro-System® was installed using no heat, providing a seamless waterproofing membrane on completion. Proteus Pro-System® is a high performance, seamless and cold-applied waterproofing membrane for flat and pitched roofs. It cures to provide completely seamless waterproof protection and has excellent thermal and UV stability, making it suitable for use in all climates.Proteus Pro-System® does not brittle, deteriorate or discolour with age. It uses atmospheric moisture to trigger its cure process and unlike conventional polyurethane systems can cure under water, without gassing or foaming. It also becomes resistant to rain damage and may therefore be applied in relatively poor weather, without any subsequent loss of performance or durability – making it ideal for Emma House.About Emma HouseEmma House consists of 14 one-bedroom and 19 two-bedroom apartments just minutes away from the centre of the market town of Romford, which offers shops, services and a wealth of bars and restaurants. When first built in 2010, Emma House offered young professionals an opportunity for affordable housing close to London and has remained at the forefront of the property market in Romford ever since.

Cranbrook Primary SchoolBauder Total Roof System (BTRS) with Tapered insulation schemeSynopsisCranbrook Primary School in Ilford, London, was experiencing some major water ingress due to the advanced deterioration of the existing roof system. A roof survey was conducted by Stuart Parratt, Bauder area technical manager, where core test samples were taken to identify the existing roof construction to deck level and to provide an indication of the roof condition. The survey revealed that the existing waterproofing was in extremely poor condition, with extensive evidence of water ingress.  Bauder Building BoardProject:Cranbrook Primary School Location:LondonProject Type:RefurbishmentRoof Area:440m² Client:London Borough of Redbridge Council Approved Contractor:Thameside Roofing Ltd The specificationThe original waterproofing had been poorly overlaid with EPDM which had subsequently debonded. Before the installers could begin laying the new system, they had to strip the substrate back to the original asphalt. The client required a robust system that would deliver durability, value and longevity. 390m² of bitumen waterproofing, Bauder Total Roof System (BTRS), was specified for the main roof areas and 50m² of our cold applied liquid waterproofing, LiquiTEC, for an area that had limited upstands due to clerestory windows that could not be repositioned. Products appliedBauderPIR tapered insulation  A lightweight and cost effective alternative method of providing falls to a roof, whilst also providing thermal insulation. The client opted for this scheme at Cranbrook to minimise standing water on the roof. Bauder Total Roof SystemA two-layer bituminous waterproofing system robust enough to withstand foot traffic and most permanently sited plant. For use within warm and cold roof scenarios, as well as overlaying existing roofing materials. BTRS meets current UK Building Regulations Part B for external fire protection and features torch-free and safe to torch installation on combustible details. LiquiTEC Cold Applied liquid waterproofing Utilising Bauder’s PMMA cold applied liquid waterproofing on one of the roof areas ensured a fully watertight solution around rooflights and below upstands that could not be raised.  Project challengesAlthough the deck appeared to be in a reasonable condition for reuse as part of the refurbishment, there were large deflections to some areas and the existing waterproofing that overlaid the original system had been poorly installed and had pulled away from the asphalt below and so needed stripping prior to works commencing. The existing insulation was inadequate and left the building falling short of the current requirements. A thermal upgrade was incorporated into the works using a tapered insulation scheme which helped to solve the deflection issues by creating falls on the roof. To meet the minimum upstand requirements, the existing extractor vents needed to be removed to allow for the increase in the kerb height. Large continuous structural rooflights providing natural light to the building below were deemed thermally inefficient. The rooflights were upgraded during the refurbishment to meet current standards.  The resultBauder systems are only installed by Bauder approved contractors to ensure quality. The installation on this project was expertly carried out by Thameside Roofing Ltd, overseen by Dave Gregory and John White. After sign-off from Bauder site technician, Paul Osbourne, this system was awarded a comprehensive guarantee.  Systems installedBauder Total Roof System (BTRS) with Tapered insulation1 Bauder K5KHeavy duty, torch-applied SBS elastomeric bitumen capping sheet featuring a spunbond polyester reinforcement to allow the finished product to cope with structural movement without fracture, and a mineral finish to provide protection against UV degradation.2 BauderTEC KSA DUO Technically advanced self-adhesive SBS elastomeric bitumen underlayer with “DUO” lap technology to ensure thorough sealing of lap joints, even in lower temperatures. 3 BauderPIR FA G16Tapered PIR Insulation board manufactured in accordance with BS EN 13165 with no facings.

This project was a re-development of an existing supermarket together with the adjoining Fulham Wharf site. It comprised the new 100,000 sq. ft store and 463 residential units with their own balcony and terrace, many with views over podium gardens and the River Thames.Systems in useWilotekt®-PlusEcoflex®Starcoat® PMMAStarcoat® QCStarcoat® RChallengesThis was a challenging site logistically with limited delivery and site access points, and the project had to be completed with consideration being given to residents and with the existing supermarket remaining fully operational. The waterproofing system had to be monolithic, fully adhered to prevent water tracking during and post construction, robust, durable and capable of withstanding construction-related traffic without defect.SolutionsCareful design consideration was provided to ensure Axter’s driving philosophy of the right system in the right place was employed successfully. The design, supply and installation of Wilotekt-Plus, unique second generation hot melt structural waterproofing system, provided 30% quicker on site installation speeds than traditional first generation hot melt systems. This ensured the waterproofing was completed swiftly, which enabled landscaping finishes to be installed within deadline.Wilotekt-Plus also fulfilled the requirement for a system that was adaptable through its approved application beneath a variety of roof finishes including ballast, decorative paving and living roofs, so as to facilitate the achievement of interesting visual aesthetics, enhancing built environment and life experience of its residents.
