"waterproofing"

Gloucester Transport Hub Bauder Thermofol PVC single ply waterproofing system SynopsisThe replacement bus station and regeneration of the surrounding area has created a unique and distinctive city centre building for the town. The design connects with Gloucester’s Roman heritage and association with aviation. The innovative roof design incorporated a canopy intended to reflect an aircraft wing that required a lightweight waterproofing and renewable energy photovoltaic (PV) solution.Bauder Building BoardProject:Gloucester Bus StationLocation:GloucesterProject Type:RefurbishmentRoof Size:1520m²Constructor: Kier Group PlcApproved Contractor:Kovara Projects LtdThe specificationThe Bauder Thermofol PVC single ply waterproofing system with the BauderSOLAR F PV solution met the brief precisely without compromising the aesthetics of the roof. This combination of Thermofol PVC single ply waterproofing system and BauderSOLAR F PV delivered a high quality, strong, energy efficient flat roof.This system was selected for the project because of its lightweight properties which complemented the deck and roof design. Light grey was chosen to reflect the colour of the cladding as the aesthetics was a key objective for the client.The OMG Rhinobond induction welding system was specified as the installation method which provided multiple advantages to the project, not only saving time and fasteners, but also optimising the field fix pattern of installation and ensuring that the load on the roof was spread between the induction welding plates. Products appliedBauder Thermofol U15 FR MembraneA high grade virgin polymer Thermofol PVC membrane ensures the optimum membrane characteristics to deliver high performance and a BBA stated life expectancy in excess of 35 years.BauderSOLAR F An aerodynamically optimised system for flat roofs using framed modules and mounting units, securing them to the roof using membrane-to-membrane welding techniques. This installation method means that the roof is not compromised by penetrations of fasteners or is it ballasted.Project challengesThe design of the Transport Hub and city centre location proved to be the key challenge to this project. The unusual roof configuration required a bespoke insulation scheme using BauderPIR M, an efficient rebated PIR insulation board, in order to achieve the required U-value of 0.18W/M²K.The deck configuration equally made the installation of the Bauder Thermofol PVC waterproofing system complex with the perimeter zone having to be carefully marked in compatability the wind calculation which included measuring factors such as wind speed, altitude, direction and exposure. Bauder and Kovara Projects were required to work closely together to ensure all criteria of the wind calculations were met. 40 modules of the lightweight BauderSOLAR PV solution were installed on the west side of the Transport Hub’s roof.The location of the project, Gloucester city centre, presented logistical challenges. Delivery of the roofing products had to be carefully scheduled and managed to avoid creating congestion in the area.The resultThe installation required constant co-operation and communication to embrace the live site operations within the restricted city centre location whilst allowing the bus station to remain fully functional. The roofing contractor delivered a superior standard solution and any complex issues that arose during the project were resolved promptly and collaboratively.System installedBauderThermofol PVC single ply waterproofing system  1 Bauder THERMOFOL U15 FR1.5mm polyvinyl chloride membrane (PVC) reinforced with a pre-coated polyester cross-weaved matting for mechanically fixed installations. 2 BauderPIR MThis efficient tissue-faced flatboard insulation has been specially developed for use within Bauder single ply systems. 3 BauderSYN DB-PE 100A blue, polyethylene air and vapour control layer.

Hydrostop AH-25 product was chosen to refurbish 450m2 of roof at the Sacred Heart Primary School in the Bridgeton area of Glasgow. Areas of the roof had been leaking, leading to considerable water damage and disruption to some classrooms. The priority for the roof works was to procure a waterproofing system with minimal hot works that would cause as little disruption to the school’s everyday activities as possible.

A green roof system was selected for this project as the client required a roof that would complement and accommodate the step in levels to follow timber decking lines to the 55m² roof terrace areas. IKO Single Ply’s Spectraplan SM120 light grey single ply waterproofing system was overlaid to the existing roof and newly built sun rooms, ready to receive a green roof system.

This project had a wide ranging number of detailing factors to overcome with cladding abutment details and change in levels to be redesigned and encompassed into a system that also drained the roof areas of their historic high levels of standing water. Some of the existing construction build had not taken into account any suitable maintenance of the roof with sections being completely inaccessible and thus reducing the performance of the waterproofing.

IKO Permatec, developed by IKO PLC, is a highly advanced and innovative hot melt waterproofing system, which provides environmental benefits as well as market leading performance. Providing zero wrapper waste, lower application temperatures and anti-root protection, the product provides many operational advantages. It is also manufactured in the UK, with a dramatically lower carbon footprint than imported systems.

The building that would be the St Margaret’s Primary School, officially opened by Robert Leitch the local parish vicar in 1889 provided education to children up to fourteen. The school underwent many changes in structure throughout its over 100-year existence continuing to provide the high level of teaching it always held. In 2012 it underwent a further change in the form of a huge modernisation project that would extend the school and allow more students to be taken. Unfortunately, leaks were reported on the older parts of the building and despite localised repairs were not ultimately solving the problem.After reports of leaks it was imperative that the roofs in question were inspected to find where the issues were originating, in action to this a site survey was undertaken. The survey highlighted the original build-up consisted of an asphalt on a timber deck, this original system was in a aged condition. It was also shown that standing water and vegetarian had developed on the roof. In order to protect the building from further leaking it was determined that the roof would benefit greatly from the installation of a high-performance waterproofing system.Along with waterproofing improvements, there would also be improvements made to the falls which would reduce the amount of standing water present on the roof.Waterproofing would not be the only recommendation; the roof was also to receive a full thermal upgrade which would further provide the benefit of increase fuel bills and less energy consumption for the school.Taking into consideration all these points, the Polyroof Technical team began creating a bespoke specification that would provide the details needed to make these recommendations a reality. The Polyroof Approved contractor Thomas Cassie & Sons was specifically chosen to undertake this project due to their experience in liquid roofing systems. With a specification and approved contractor ready the project could officially commence.

Contractors Penenden Heath Developments were selected to install the waterproof system at a four-bedroom property at Darland Farm in Hempstead near Gillingham, Kent. Thanks to the proven properties of Sika’s dual watertight solution, the property’s future occupiers can enjoy the comforts of their classically-designed rural retreat safe in the knowledge the structure will retain a robust defence against whatever elements the exposed location provides.

The Burrell Collection’s renaissance is an ambitious refurbishment which will allow visitors to explore all three floors in the building, set out as galleries, visible stores and special exhibition spaces. Arup was tasked to improve and reinstate the entire envelope of the building. The goal for the failing metal standing seam roof was to replace it with a new waterproofing system incorporating falls to provide effective drainage and to incorporate sustainable technology in the form of solar PV.

The Westfield Centre in Shepherd‘s Bush has one of the largest roofs ever designed in central London to cover the retail floor area of 150,000 m² (about 30 football pitches).The centre was developed by the Westfield Group at a cost of £1.6bn, choosing PermaQuik over the huge selection of waterproofing systems to provide the long term security necessary to protect one of the most expensive areas of retail space in the world.

Bury St Edmunds Train Station required building envelope works due to the ageing condition of Grade II listed building managed by Walker Construction. A significant issue was water damage caused by water ingress through an inefficiently waterproofed roof, invasive plant species growing through brickwork, and debris around drainage points.The solution:AlphaGuard PUMA Liquid Applied Flat Roof System

The Faculty of Humanities and Arts is the third largest faculty in the Macau University of Science and Technology, The construction of the Complex Academic Building of College of Humanities and Arts – Block “R” includes a 2-storey basement and 7-storey above the ground floor. The height of the building is 30.75m. Caltite System has been applied in the basement slab, (B1 to B2), basement wall and water tank for long-term reliable waterproofing.

Five domed design... CHALLENGE The idea of the architect was to design a building with 5 parabolic roof surfaces or domes. The unique five domed design comprises of pods finished in a range of different materials, each contributing to the development’s remit to blend into the park landscape. The biggest issue for the architect was how to connect these different materials to become a complete watertight building. SOLUTION Each dome is waterproofed using a RENOLIT ALKORPLAN system and whilst the complex is thought to be the UK’s largest timber-built geodesic project, it also demonstrates possibly the most innovative use of single ply membrane ever seen in the UK. By using the RENOLIT ALKORPLAN membrane as the main layer to waterproof the five domes an easy joint could be made by means of hot air. On one dome our RENOLIT ALKORPLAN A membrane was used in combination with PVC profiles providing geometric aesthetic detailing. On another dome a RENOLIT ALKORPLAN L membrane was used under a green roof system. On the other domes the RENOLIT ALKORPLAN F membrane was used in combination with our RENOLIT ALKORSOLAR fixing system supporting respectively glazed aluminium sheeting and cedar shingle tiles.

The Bourne Academy, Bournemouth was to undergo a £10 million renevation, a project that would include many newly constructed areas. The building was dreary and outdated, and to create an aspirational environment, to inspire students to achieve, it was necessary to greatly improve the facilities. The main part of the brief was to cover an area surrounded by 3 buildings with a tensile canopy. Curtain walling was required to the open side, along with fabric side sheets incorporating clear windows and a printed logo of the school.Broxap Ltd was successful in tendering to supply a range of its products throughout the Academy.Working with its designers, the client and the architect, Broxap developed a suitable scheme.Products included several Newcastle Senior mono-pitched covered walkways and Newcastle Senior symmetric walkways.The Keep It Kool division of Broxap provided four Cairns perimeter beam waterproof shade sails, a barrel vault entrance canopy and a large bespoke waterproof tensile canopy. The bespoke canopy spans an enclosed central eating and socialising area, which is laid with artificial grass.Other products supplied were Wardale cycle shelters, Wardale cycle compounds, picnic units, seating, barriers and planters.

Reigate & Banstead Borough Council is transforming Marketfield Way, Redhill, with a brand-new leisure, retail and residential development. The 0.59-hectare site will turn the western side of Marketfield Way into a vibrant destination for both property seekers and visitors to the local area. It is made up of the Council’s former Marketfield Way surface car park and a group of retail and commercial buildings fronting 18-44 High Street.Features of the scheme include:A new multi-screen cinema hosting 7 screens11 new units for restaurants and shops on the ground and first floors150 new one- and two-bedroom homes to be privately rented within buildings up to thirteen storeys in heightLandscaping and public space improvements including a ‘galleria’ pedestrian route through the site flanked by shops and restaurants.The waterproofing and gas proofing of the new mixed use scheme basement area and ground floor was a crucial element of phase 2 of the project. Reigate and Banstead Council therefore called upon contractor Vinci Construction to undertake the waterproofing works, utilising Sika’s solution provided through subcontractor Oliver Connell & Son Ltd

A number of the building’s roofs at Roundwood Park School needed refurbishing to prevent further water ingress entering the classrooms below. The client wanted the new waterproofing system to be of high quality and provide falls to the roof to help mitigate ponding water. A no capital outlay PV solution and new rooflights were also desired as part of the works to optimise the roofs functionality. The school remained open throughout the project creating logistical challenges.

Sika supplied a single-source warranty as part of a dual waterproof solution for a large, privately-built concrete basement to guarantee its long-term protection against the perils of damp and water ingress.The 153m2 basement was part of a new build house in Harpenden, Hertfordshire. A toilet, cinema room, games room and a plantroom are earmarked for the below-ground structure; therefore its long-term resistance to water ingress was paramount.

SIG Design & Technology and SIG Insulation are working with the Interserve Kajima consortium on a batch of seven secondary school projects to deliver a value-engineered, robust roofing solution. At Stopsley High School there are two roofs installed by Briggs Amasco in an approximate 16 week programme. The largest roof measures some 2500m2 and the inverted roof build up selected and supplied by SIG comprises IKO’s PermaTEC hot melt waterproofing system.

Players at Macclesfield FC enjoyed a speedy win thanks to the help of Styccobond F58 PLUS. The ‘no time to wait’ adhesive made quick work of the installation of LVTs and rubber floorcoverings as part of the creation of a new state-of-the-art gym at the Leasing.com stadium.  Flooring contractors began the project with a subfloor moisture test, which indicated high Relative Humidity (RH) levels in the subfloor, necessitating a moisture management solution to prevent excess subfloor moisture attacking floorcoverings and adhesives, potentially causing floor failure. Having removed surface laitance and old paint from the concrete subfloor on the lower floor, the contractors carried out surface repairs using Stopgap 460 Exterior Repair fast-setting rapid repair mortar. A single coat of Stopgap F77 waterproof surface membrane created a barrier against the excess subfloor moisture. Once the waterproof surface membrane had cured, the surface was primed using Stopgap P141 primer for non-absorbent surfaces before the company’s Red Bag self-levelling compound was applied at a thickness of 3mm to provide a perfectly smooth base for floorcoverings.   Styccobond F58 PLUS was used to affix charcoal-grey, wood-effect Kährs Calder Herringbone LVTs to create a bold statement in the main weights, cardio and boxing rooms, and changing areas.  Throughout the gym, rubber floorcoverings were also installed at fitness stations, using the adhesive in its wet state, to provide a soft cushion underfoot for customers using the equipment.  Upstairs, contractors made necessary repairs, including filling day joints, before priming the subfloor, this time opting for Stopgap P131 general purpose primer. Due to high RH readings contractors applied Stopgap F78 waterproof surface membrane. Once cured, Stopgap Red Bag self-levelling compound was again used to create a base for subsequently installed LVTs, completing a premier workout area for strength and resistance and cardio machines.

The proven, durable properties of Sika’s high-quality waterproofing system were required to ensure the successful upgrade of one of the UK’s busiest rail terminals.The multi-million pound refurbishment of London Bridge station – which brings an estimated 56 million passengers into the city each year represents a huge undertaking by Network Rail to create new connections and increase peak hour services by 30%. The project is part of the government-sponsored Thameslink Programme.

The British Horse Society headquarters is on a listed deer park with many protected trees. The building’s circular design posed key construction challenges. The single storey office building was constructed in a doughnut shape, to ensure that a mature oak tree on site was preserved. In keeping with its green surroundings Spectraplan SM120 Dark Grey, a polyester reinforced TPE waterproofing system was mechanically fixed to a composite metal deck, ready to receive a sedum blanket.

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

Whitburn Partnership Centre was designed by Project Architects, Matthew Fair, Neil Forrester and Jamie Bateman at Smith Scott Mullan Associates for West Lothian Council. The design of the contemporary £4M building restores the historic Whitburn Burgh Hall original façade as it is one of the towns most renowned buildings and incorporates a new-build two-storey extension.Located in the centre of Whitburn, this building is a community hub that embraces the West Lothian Council’s model of bringing together services that benefit local communities whilst delivering financial efficiencies through the decrease of council buildings. This building facilitates a library, community halls, museum and customer information service office, making it an important community resource. Project:Whitburn Partnership CentreProject type:New buildLocation:West Lothian, Scotland,Waterproofing:Bauder Total Roof System (BTRS)Roof size: 525m2Energy generated from PV array: 10.35kWp Specifier: Smith Scott Mullan AssociatesMain Contractor: Maxi ConstructionApproved contractor: ProCladd (Scotland) LimitedSolar PV installer: Intelligent Electrical SolutionsThe specificationTo support the West Lothian Council's sustainability objectives of achieving high energy efficiency, it was our responsibility to specify a waterproofing system and provide a solution for natural energy generation. The bituminous Bauder Total Roof System (BTRS) was chosen for this project as it features membranes that can withstand impact and tearing, as well as thermal insulation that met the required U-value of 0.15 W/m²K. This waterproofing system is verified by the BBA and offers a service life in excess of 35 years.The BauderSOLAR system was also specified, as it incorporates photovoltaic arrays for natural energy generation. The photovoltaic mounting system is attached to the roof without penetration of waterproofing or the deck, safeguarding the integrity of the waterproofing to fulfil its full-service life.Project challengesThe Architect’s design incorporated unusually high parapet upstands, which posed a challenge for installers. Area technical manager for Bauder, Christopher Langton, attended design meetings with the Architects and Main Contractor to discuss the best solution for installation. A mutual agreement was made for the underlayer to be mechanically fixed to prevent any slippage of the capping sheet membrane. Due to the height of the upstand, non-combustible insulation BauderROCK was incorporated into the design at these details.The installation of BauderSOLAR F uses prefabricated bituminous BauderK5K membrane sleeves to slip over the mounting plates and welded into position, anchoring the plates to the surface of the Bauder waterproofing system. Approved BauderSOLAR installers, Intelligent Electrical Solutions, installed the BauderSOLAR system, collaborating with ProCladd, approved contractor for the waterproofing installation, and other trades during the roof installation.There is a junction where the flat roof meets the original slate roof of the adjacent building, this detail fell under the torch free zone that hot air welding techniques are used to install the membranes within these areas.The resultInstallation of the Bauder waterproofing system may only be carried out by trained and certified operatives approved by Bauder. A project pre-start meeting was held by Bauder site technician, Duncan Hastings, and area technical manager, Christopher Langton inviting the Site Manager from Procladd and their Bauder badged operatives. During this meeting, they discussed the installation of the project, and identified the areas that required torch-free and torch-safe detailing. They also discussed how the project was going to be delivered in co-ordination with other trades working on the site at the same time, for example cladding and lead that was installed atop the waterproofing upstand details.Weekly site-inspections were carried out by Bauder site technician, Duncan Hastings during the project. Visiting the site frequently meant that Duncan could provide consistent support to the installers and answer any questions they may have had directly. It also meant that the quality of the roof installation was being monitored regularly to ensure it would be to a high standard, achieving the comprehensive guarantee.The approach taken to deliver this project on time and to budget was through meticulous planning and working to tight time frames. The organisation of the delivery of Bauder products to site had to be in line with the schedule to ensure that the site was ready to receive a delivery. With the project located in the busy centre of Whitburn next to a cross junction with traffic lights. This meant that timed delivery of products to site was required in addition to prebooked off-loading by pump truck and tail lift or by telehandler.Health, safety and environment was managed during the planning, design and installation of this project by advising that all installers follow the advice shown in the “Responsible Specification Checklist” produced by the National Federation of Roofing Contractors.In accordance with the Workplace (Health, Safety and Welfare) Regulations 1992, roof edge protection in the form of scaffolding was installed during installation. The project’s perimeters were surrounded by Heras fencing to isolate the construction site from the public. All scaffolds that were on the elevation next to the public had toe boarding and safety mesh where required.As standard, there was a one-hour Firewatch after the Bauder membranes have been installed using a gas torch. This was carried out by Procladd operatives each day when they were working on the project to ensure the welfare of the workforce, and the safety of other trades and that of the building. The 19kg gas cylinders were used on this project as they are easily transportable on the roof area. At the end of each working day, the cylinders were stored in a locked and designated gas storage unit on site.System installedBauder Total Roof System (BTRS)1 BauderK5KElastomeric bitumen torch-on capping sheet in charcoal grey.

Located in the heart of Central London, Bloomberg L.P.’s stunning new European headquarters is now operational. Located in the heart of London between the Bank of England and St. Paul’s Cathedral, the building had to meet modern-day efficiency expectations while establishing itself as a notable visual icon within such constantly developing and advancing city.Radmat and Prater were contracted to supply and deliver the installation of the waterproofing and thermal insulation to parts of the building, most notably its green/biodiverse roof.

Ilona Rose House with its unusual rose-coloured 3D printed façade is a new-build, mixed-use project spread over 13 floors, including a 4 storey, basement with a quarter natural light. It has transformed the former site of the famous Foyles bookshop on Charing Cross Road, boasting outstanding new shops and restaurants, along with new pedestrian walkways, public realm and roof terraces.The unique building has been designed by MATT Architecture for main contractors Sir Robert McAlpine and offers 150,000 sq ft of office space, 20,000 sq ft of retail fronting on Charing Cross Road and a brand-new public courtyard with 15,000 sq ft of restaurant and bar space.The upper floors comprising of offices exploit the stepped massing of the building to create over 12,000 sq ft of planted external terraces for the benefit of the occupiers and to enhance the environment.The south-west facing terraces, nicknamed ‘the hanging gardens of Soho’ will provide external amenity space for every single level of office. It is here that Radmat’s waterproofing and insulation products were chosen for their tried and trusted properties. PermaQuik Hot Melt Bitumen Waterproofing System was used on 95% of the roof areas, multiple roof terraces, Greek Street Tunnel and James’ Courtyard.

Products donated by F. Ball and Co. Ltd., including the company’s Stopgap 1200 Pro levelling compound, have been used to prepare subfloors as part of the renovation of the Coventry Caribbean Community Centre prior to its reopening to coincide with Coventry’s UK City of Culture status last year. Firstly, they removed old floorcoverings, revealing a rough screed. A moisture test also indicated that subfloor relative humidity levels were above the 75% maximum threshold for installing floorcoverings. Installers therefore opted to use Stopgap 1200 Pro to smooth subfloors.Stopgap F77 one-part waterproof surface membrane was then applied to prevent excess subfloor moisture attacking floorcoverings and adhesives, potentially causing complete floor failure.Once dry, the surface was primed using Stopgap P141, which is designed especially to promote the adhesion of levelling compounds to non-absorbent surfaces, including waterproof surface membranes. Another layer of Stopgap 1200 Pro was then used to create a perfectly smooth base for the receipt of new floorcoverings.Once the levelling compound had cured, Amtico Spacia stone-effect LVTs were installed in the majority of the floor area, with cream-coloured hexagon tiles positioned around the bar area for visual interest.

We have recently completed a 600m2 project in Westminster with installation by one of our main Approved Contractors, Ridgewell Flat Roofing.Specification – System UsedThis project called for extremely durable yet cost-effective waterproofing to be installed, which made the OptiTorch-Premium Bituminous Felt System the ideal choice. Having been used in the roofing industry for over 50 years, felt has been consistently developed and improved, and still remains one of the most popular systems available.OptiTorch-Premium bituminous felt is a high-performance waterproofing system that can be installed year-round, with excellent flexibility at temperatures as low as -25oC. This system provides long lasting resistance against UV rays and even contains special additives to protect against root growth.There was also a lot of detailing work and some gutter repairs required, so OptiFlex-Rapid PMMA Liquid was used for these parts of the project to ensure a completely watertight and visually appealing result.OptiFlex-Rapid is a quick-curing PMMA liquid waterproofing system with a typical curing time of just 20 minutes! It is cold-applied and is reinforced with 150gsm matting for extra resilience.
