"roofing membranes"

The Metro Centre is over 22 years old and the building had been experiencing leaks, a problem which was exacerbated by the numerous changes in plant installations on the roof. The original felt waterproofing had reached the end of its working life and a system was required that would keep the building watertight, help comply with current building regulations, and bring the insulation standards up to Part L. A Cold Bonded Built-Up Roofing System was specified for the project consisting of 40mm Decotherm insulation, a Carrier Membrane, and a seamless Decothane Gamma 20 waterproof ‘cap sheet’.

The Ascent Up and Over step unit / Industrial stair system was specified to create a safe means of access up & over items of mechanical plant & equipment to the roof of the airport terminal building. The Industrial stair unit is supported on rubber spreader feet which provide a non-penetrative support solution on the flat single ply membrane roof. The stair unit is designed in accordance with BS EN ISO 14122-1:2001 + A1:2010 and Building Reg Part K:2013 and manufactured following 1090 factory production control procedures.

A contractor client was working on a retro-fit balcony and flat roof project in Brighton. The waterproofing membrane had tapered insulation placed on top and the contractor discovered ballasting the insulation was needed, only once on the roof. The door thresholds were too tight for a traditional decking system with joists. Wallbarn advised for paving slabs on 9mm rubber pads; then 30mm thick ipe timber tiles mounted onto Adjustable Pedestals. The buildup was under 100mm and the overall finish of the tropical hardwood was glorious. The architect was relieved that we could produce a solution, the client was delighted.

Renovation stripping out the building completely and rebuilding the walls, Passive Purple® was applied in between the connections of the internal side of the external walls which were a combination of masonry, timber, and steel frame. The ground floor ceiling was removed exposing the warped old timber joists with cracks in the surrounding brickwork and mortar. This was given attention to detail using Passive Purple® Brush to seal above an airtight foam to guarantee the airtightness of this major air leak zone before the final spray coat of Passive Purple® airtight membrane was applied. Passive Purple® was also used to seal window and door linings, ready for the new triple glazed windows to go in. Passive Purple® was sprayed on all the walls and ceiling. This is an ongoing project that still is awaiting an air test, the client is looking to hit 2.5 ach and installing MVHR.

Coláiste an Chláirín Bauder Thermofol single ply waterproofing system with BauderROCK insulationSynopsisThe new Coláiste an Chláirín building in Athenry, Co Galway is a post primary school consisting of classrooms, a special needs unit, sports hall, general-purpose hall, staff amenities and extensive external facilities designed by Smith Kennedy Architects & Healy Partners Architects. The project was managed by JJ Rhatigan and Company and the roofing element appointed to Priority Roofing and Cladding Ltd. The roof of the main building and the gymnasium required flat roof build-ups to meet the specifications as set out in in SDG 02-05-03 (Acoustic Performance in New Primary & Post Primary School Buildings), while meeting the general performance requirements specified within TGD 021-7 2018 (Minimum Performance Standards of Roof Materials and Finishes). The chosen system had to meet an acoustic performance of 35dB indoor ambient noise level (IANL). It was decided that, despite sports halls having a slightly higher IANL threshold, the 35dB performance criteria would be applied across all areas of the school, with control of reverberation being a key consideration in the gym.Bauder Building BoardProject:Coláiste an ChláirínLocation:County GalwayProject type:New BuildRoof size:8550m²Main contractor:JJ Rhatigan & CompanyApproved contractor:Priority Roofing & Cladding LtdThe specification:The Architect specified that the insulation used in the flat roof system should be non-combustible and achieve a U-value of 0.16Wm²k which actually exceeds the thermal requirements as described in the Irish Building Regulations Technical Guidance Document L for flat roofs in schools.BauderROCK was specified to achieve the thermal and acoustic requirements of the design. As a Euroclass A2-s1,d0 non-combustible material, BauderROCK also provided the specified fire performance. This insulation could be used across all roof areas, with some adaptations for the gym which required additional acoustic performance due to the inherent nature of the space. Acoustic infills were used in the troughs of the perforated metal deck, thus combatting the reverberation of the indoor environment.  Products appliedBauder Thermofol PVCAn integrated single ply waterproofing system, featuring a lightweight, cost effective membrane which offers a pleasing aesthetic finish on a flat roof. This system holds fire classification BROOF(t4) for compliance with building regulations under TS 1187 test method 4 for external fire exposure to roofs. BauderROCKHigh density mineral wool insulation.Project challengesOne of the challenges of this project was the ambitious schedule. The use of the self-adhesive air and vapour control layer (AVCL) enabled the trades working within the building to progress quickly without being delayed by weather conditions. BauderROCK is relatively quick to install, as was the lightweight single ply waterproofing.  The resultThe project was finished to time and specification with exceptional workmanship from the fixers at Priority Roofing and Cladding and superb collaboration from all parties throughout. The membrane was finished with standing seams to create a statement look. The roof achieved a U-value of 0.15 W/m2k, exceeding the thermal target, and met or exceeded the 35db IANL requirement across the main building and the sports hall.  The thermal performance, which will hold up for decades to come, will also impart energy efficiency benefits that reduce running costs at the school in the long term. Finally, the non-combustible nature of the mineral wool insulation ensured that the build-up met the fire safety specification. System installed Bauder Thermofol PVC single ply waterproofing system1 Bauder THERMOFOL U15 V FRThis 1.5mm polyester reinforced Poly Vinyl Chloride membrane (PVC) membrane benefits from being highly flexible due to the incorporation of internal plasticizers during the manufacturing process. The combination of materials within this membrane provides high tensile strength, with thermal stability and chemical resistance.2 BauderROCKA mineral fibre non-combustible insulation with high acoustic performance. The dual density mineral wool composition delivers compressive strength, whilst keeping the overall weight to a minimum and providing high noise absorption which enabled the complete system to meet project requirements.3 BauderTEC DBR 06This 0.6mm, self-adhesive, elastomeric air and vapour control layer is light weight and benefits from cleaner, safer, and faster installation than traditional torch applied membranes. Advocacy Niall Hanley, Contracts Manager at JJ Rhatigan, the project’s main contractor, said:"Coláiste an Chláirín Athnery was a great success and in particular the use of the self-adhesive AVCL in advance of the build-up allowed works to commence immediately internally, which was critical from a programme perspective.” Kevin Ryan, Director at Priority Roofing, explained:"We found the system both practical and efficient to install. The combination of the availability of the products and the technical backup received was superior to any other system that we have worked with.”  Eoin O’Grady, Associate Director at Healy Partners Architects commented:"We are delighted with the overall delivery of the roof build-up and the performance achieved. The PE hall solution to deal with reverberation noise as well as rainfall noise was very successfully managed. We look forward to working with Bauder on future projects.”

Canberra HouseBauder Cold Applied LiquiTOP SystemSynopsisCanberra House is an office facility in Swindon. The existing single ply PVC waterproofing system roof was leaking and so Bauder carried out a full site survey. The resultant report gave the client several options to rectify the leaking roof.Bauder Building BoardProject nameCanberra HouseLocationSwindonProject typeRefurbishmentRoof size985m²SpecifierRapleys LLP (Bristol)Approved contractorCentral Roofing & Building Services LimitedThe specificationThe LiquiTOP system was chosen as it can be applied directly to the prepared and primed existing single ply covering. The liquid system allowed us to get into tight spaces and without the need for any hot works.LiquiTOP is excellent on refurbishment projects where the complexity of the roof involves intricate areas to be detailed that are not easily achieved with a sheet membrane, or the actual working space on the roof is constricted.Project challengesLarge areas of plant and machinery were situated just above the roof level making access to the areas below difficult with the plant in-situ. The available budget on this project did not allow for lifting or removing the plant, stripping the existing waterproofing system, and replacing with new. Therefore, the decision was made to overlay the existing single ply membrane with a cold applied liquid waterproofing which can be installed without the need to raise any plant.To overcome drainage challenges, secondary upstands were created under the plant and fabricated channels placed underneath allowing water to flow through to the drainage points.The resultBauder was able to offer a cost-effective solution without the necessity to remove or decommission the roof mounted plant and machinery. Cost reductions were achieved for the client by overlaying the existing roof, negating any need to strip existing materials, and not having to remove or raise the plant.The works were carried out by Central Roofing who manged the project impeccably and also finished ahead of schedule.System installedBauder Cold Applied LiquiTOP System1 LiquiTOP PU cold applied liquidA moisture triggered curing polyurethane waterproofing resin; applied in 2 coats, reinforced with Bauder LiquiTOP Glass Fibre Mat.

The project resulted in improved water runoff, enhanced durability, a more aesthetically pleasing roofing solution, along with a new 60+ year life expectancy. This case study emphasizes the importance of selecting innovative and reliable roofing systems to overcome recurring roofing issues and deliver long-lasting and visually appealing outcomes.

The project consisted of two similar flat roof areas totalling 1,100m2 above high-rise residential blocks in a city centre location. The existing roofs were an inverted roof design that had been waterproofed with single-ply that had failed prematurely. Numerous short-term, localised repairs had failed to stop the water ingress and leaks had been a long-term problem.It would have been impractical to remove the tons and tons of ballast and insulation from the top of the high-rise building and it was imperative to the client that removal or replacement works were not involved at all. The specific nature of this project required careful consideration, and so a survey of the roof was arranged.The SolutionA report from an independent consultant commissioned by the client identified a problematic challenge with an overlay option. The existing falls of the roof were assessed to be poor, and so standing water would be an issue for any new waterproof covering. The report concluded that this would reduce the lifespan of an overlay waterproofing system and so was advised against. The client initially thought this to be a stumbling block and that costly and impractical modifications to the roof would need to be made.Having worked with Polyroof on scores of other projects, the client turned to Polyroof Technical Services for a solution that could meet their stringent criteria. Following on from the preliminary discussions, Polyroof’s Technical Services assessed the site, taking core samples and then providing a suitable specification to overlay the roof with the Protec System.The BBA certification of the Protec system specifically covers use for zero falls (completely flat) applications, meaning the client had absolute peace of mind that standing water would not be a detriment to the integrity of the waterproofing system. The client was able to achieve the original objective of an overlay system and benefited from the associated cost and time savings. Furthermore, the BBA certificate states that when used in inverted roof scenarios the lifespan of the Protec system is as long as the design life of the roof.Work was started with J R Flat Roofing, a Polyroof approved contractor with national coverage, moving the ballast and insulation to one-side in four phases of 140m2 at a time, exposing the single-ply membrane to which the Protec system was directly applied.Due to Protec’s rapid cure and walk-on times (30-60 mins dependent on conditions), the system is ideal for larger, phased refurbishment, as specific sections of the roof can be made waterproof with the full Protec system in one day. When carrying out the next section, the new Protec membrane forms a totally seamless and watertight joint to the existing Protec-covered areas.Another objective was to reuse the original inverted insulation and ballast pebbles as this was cost saving and negated the need for the lifting logistics that would have been involved in bringing the ballast to ground level. Additionally, it made the process as environmentally compliant as possible by keeping waste to a minimum. The insulation and pebbles were re-applied in its original format and, due to the weight of the pebbles, was a mammoth task that required three miniveyors to help with the handling. A series of special aluminium breather vents were also fitted down to the concrete slab roof substrate to enable the surface to dry out over a period of 12 months.The whole job was completed in three weeks and the client was delighted with the finished work. With a 20-year insurance back-guarantee and a maintenance-free waterproof membrane that will last as long as the roof stands, the client was once again left with total peace of mind that their buildings could not be better protected.

The Lanesborough 5-star hotel on Hyde Park Corner, Knightsbridge in central London; is operated by the Oetker Collection, and is reputedly the most expensive hotel in the city.All the rainwater outlets on the roof were in need of replacement, and Holborn Asphalt needed a simple, effective solution that would be compatible with the waterproofing membrane that they were installing.An extensive number of our FarBo rainwater outlets were selected for this project - these outlets are perfect for this type of work as they fit neatly into any existing drains and downpipes.

This is an asbestos cement roof coating and refurbishment project completed by Liquasil Approved Installers, Nadco Ltd. The roof was first cleaned and all cracks, small holes and fixings sealed with Liquasil Non-Sag Sealer, providing a permanent seal. The entire roof surface was then coated with the BBA Approved Asbestsoeal 20 asbestos roof coating system.

We all know warm roofs and joist zones are huge areas for air leakage and extremely hard to solve this problem. This warm roof structure for luxury apartments retrofit fit onto an already existing block of apartments in Tottenham was typically the icing on the cake for detail and performance. With the hand cut roof providing the client with multiple skylights, dormers and 360-degree turrets, this was going to be no easy task of getting the airtightness and vapour control secure and correct in a traditional method. Step forward Passive Purple! Rather than just covering the issues, once the hand cut roof was finished, the 220mm roof rafters were filled with a layer of spray insulation supplied by Lapolla UK. The dormers, skylights and turrets were then given some attention to detail with Passive Purple BRUSH before the final application of Passive Purple (spray applied) This gives this roof a complete airtight vapour control with performance like no other and getting around all of them circular details and angle’s galore this was just another simpler, easier way to get the job done right and guaranteed! Passive Purple liquid application saves the client and user so much time and so much less strenuous labour.

Fulham JettyBauder Bakor 790-11 hot melt structural system with Bauderflex waterproofing system and BauderGREEN sedum systemSynopsisFulham Wharf is a landmark regeneration scheme that began in 2013 and included the ecological enhancement of an abandoned jetty on the River Thames. This redevelopment was designed to provide the local community with an ecological education centre and bio-diverse wildlife reserve.Bauder Building BoardProject:Fulham JettyLocation:LondonRoof Area:1,000m²Specifier:FabrikApproved Contractor:Accurate RoofingProject challenges One of the major challenges for this roof was installing the central sloped section, which required exceptional levels of technical input and workmanship. This roofing area was waterproofed with the same bituminous green roof system as the upper roof; however a special timber design for retaining the substrate and sedum blanket was also needed. Since its official opening in October 2013, the lower wildflower roof has become a haven for a variety of different birds and insects.The resultThe building’s new roof swoops down to become a continuum with the jetty deck and is covered with a green habitat providing three distinct environments for wildlife; one on the flat roof, one on the slope and the third on the jetty deck. The education centre roof was waterproofed with Bauder’s root resistant bitumen membrane before then having a sedum blanket fitted. On the lower roof, 650m² of Bauder’s hot melt structural waterproofing was installed along with a wildflower blanket, providing an instant carpet of vegetation. Systems installedBauderflex bituminous waterproofing system1 BauderPLANT E 42A torch applied, SBS elastomeric bitumen capping sheet.

The Shetland Museum and Archive Centre at Hays Dock in Lerwick was built at a cost of £11.6 million which was part financed by the Heritage Lottery fund. The walls of the Museum were constructed in the shape of a fishing boat sail and the building won a prestigious design award from the Glasgow Institute of Architects. The harbour is regularly battered with wind speeds in excess of 100mph and Hertalan membranes were specified to waterproof the roofs and fa çades of the building due to their durability, BBA, ISO14001 and WINTEC certification and the products 20 yr manufacturer warranty.

Private house, Jersey CHALLENGE Glulam beams – or glued laminated timber – are an ideal light weight alternative for steel or reinforced concrete that allow for much longer spans, heavier loads and complex shapes. Over the years timber rot may occur to such a degree that renovation becomes imminent and irreversible. That’s exactly what has happened to the property of a Jersey customer of RENOLIT’s approved contractor Advanced Roofing. A solution was sought to “save” the existing Glulam beam structure without too many structural changes. SOLUTION The RENOLIT ALKORPLAN roofing contractor solved the problem as follows: For the first stage they removed the failed, rotten areas and treated the remaining areas for insect infestation. Then they covered the glulam beams at each change of direction with RENOLIT ALKORPLAN metal sheet. Over the metal the beams were completely wrapped in reinforced RENOLIT ALKORPLAN membrane. Nicely packed… and completely waterproof. It worked really well and actually quite an ingenious idea! The glulam beams can start a second life resistant to all weather conditions. Once the glulam beams were encased there was still the issue of the solar shading to be re-fitted. Preferably without having to penetrate the newly applied membrane! The brilliant idea of using RENOLIT ALKORSOLAR profiles welded to the top edges of the glulam beams as a safe and solid support for the solar shading evolved. This project is again an excellent proof of the versatility of our RENOLIT ALKORSOLAR mounting system.

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 venue has been designed by UK-based EPR Architects, with the hotel interiors designed by New York-based designer Thierry Despont, and the residences by 1508 London. A1 Fire Rated Breather and Vapour FR Membranes were used to protect the insulation and building interior, maximizing its energy efficiency and value.

The now disused St Margaret’s Head Tunnel was a structure originally formed as part of the Dunfermline to North Queensferry railway line, providing a link to the ferry service until the opening of the Forth Bridge in 1890 and remaining in limited use for freight until 1954. The vaulted roof and brick lined tunnel is located 15 metres below the A900 trunk road and the B981, adjacent to the northern approach to the Forth Road Bridge. Cordek were asked to supply a structural fill solution, encapsulated within a protective membrane to fill the entire cavity of the tunnel.
