"waterproofing"

Following the success of the Shoreline and Ocean hotels at Butlins’ Bognor Regis Resorts, the Butlins Wave Hotel is the newest addition, with the widest range of accommodation options. All three have been waterproofed by the Roofline Group. Cefil single-ply roofing membrane covers tapered insulation, with Fixfast tube washers and fasteners holding it all in place against the prevailing sea winds."We always get good service from you guys - that's the main reason we've stayed with you all these years"Bryan Lock - Project Manager at Roofline Group Ltd

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 original waterproofing on the Maternity Hospital roof had exceeded its serviceable life and begun experiencing water ingress, requiring urgent remedial work. Bristol City Council wanted to optimise the roof area by installing a high quality, long lasting PV array that would contribute to its Solar City scheme that aims to provide one gigawatt of solar power to Bristol by 2020. The installation needed to cause minimal disruption to ongoing work at the hospital and insulation upgrades were necessary to ensure the roof achieved the required 0.25 U-Value.

The Gunnery, Kent is a unique and interesting project. Delta Membranes were appointed as Waterproofing Designer to transform an unused fort/home in Kingsdown, Kent. The building was situated 92ft on a cliff edge. The Gunnery was originally a military base with extended underground rooms and thought to have ‘secret rooms’ underground. The building had suffered from fire damage as well as vandalism over the years and had been left to ruin. During a site visit various considerations were given to what Delta product would be best suited to the job, given the restrictions imposed by the existing structure.

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.

This was a major refurbishment and landscaping project for an office development in the City of London. A podium deck had been re-waterproofed and the area landscaped, by contractor Scotscape, with a mixture of hard surfaces, grass lawns, planters and borders. Wallbarn has a very wide range of pedestals for a variety of applications. So we were able to supply exactly the right pad to best support the 6 x 2” joists the landscaping contractor needed to hold their decking boards. The timber joists were fixed into a frame and rigid insulation placed into the cavities between the beams.

Our technical team were invited to complete a roof survey and condition report of this residential project, where the existing roof area which was suffering from repeated leaks, failed repair attempts and significant standing water.ChallengesUpon inspection it was clear the roof covering had been recently renewed, but the workmanship, attention to details and drainage falls were sub-standard and no doubt contributory to the ongoing leaks and consequential ceiling damage to the areas below.Although the client preferred a robust torch-applied reinforced bitumen waterproofing system, our Safe2Torch assessment picked up some redundant roof plant, combustible cladding interfaces and complex penetrations which necessitated a localised flame free solution.Our team also carried out a level-survey to ascertain the existing falls, and what, if anything, could be done to alleviate the standing water without excessive cost.SolutionsOur comprehensive roof survey report included a dimensioned roof plan, identification of Safe2Torch areas/details, bespoke waterproofing designs for complex penetrations, and a thorough assessment of the existing roof make-up (via core samples) and drainage.Given the apparent age and good condition of half the roof area, it was left in-situ and overlaid with Hyranger single layer RBM system. Minor improvements to the drainage layout, via the introduction of a tapered insulation scheme central to the roof where the outlets where positioned, helped to significantly improve falls. Elsewhere, the rest of the existing roof covering and thermal insulation were stripped back to expose the original asphalt.The asphalt received a new air and vapour control layer before the same Hyranger system, including a mix of both flat board and tapered Hytherm ADH insulation, was installed to improve the falls and correct the thermal performance balance.A Safe2Torch abutment detail to existing cladding was identified early on in the Axter roof survey report as a fire safety hazard, so in accordance with our specification and recommendations, our accredited Axtershield Installer - N R A Roofing & Flooring Services Ltd - expertly installed a Hyranger Neo-Bitumen Flame Free membrane solution around a 900mm wide margin.The Axtershield Installer worked efficiently and to a very high standard to complete the project on budget whilst delivering an aesthetically pleasing and robust waterproofing solution.Systems in useHyranger®Neo-Bitumen® Flame Free

Sika Liquid Plastics has specified and supplied a roof upgrade solution for West Suffolk Hospital to renew the waterproofing membrane on multiple areas of the hospital campus and create a gradual pitch to aid drainage while enhancing the building’s thermal performance. Delivered by specialist contractor, Allard Construction, the phase four programme included seven sections of the building in a 20 week programme. The seven areas that needed work were all under heavy coverage of mechanical plant and pipework, and consequently there were large areas of restricted access, these issues made Sika Liquid Plastics the perfect choice for the project

Harris Academy Secondary School is a 6 form-entry secondary school in London. The project brief was developed with London Borough of Sutton and Harris Federation, together with multiple stakeholders and the surrounding community. Architype, a top London based architect, were asked to design a new school which could meet Passivhaus standard and also go on to meet BREEAM requirements. The requirement of this high quality development was the integration of environmental sustainability, user comfort and well-being. To meet these requirements they needed a high quality roof specification which could offer thermal insulation and a high performance waterproofing solution.

F. Ball’s high performance subfloor preparation and adhesive products have been used to renovate the floor of a 160m2 school hall at Christ Church CE Primary School in Kent. A combination of Stopgap 600 deep section base compound and Stopgap 200 Smooth acrylic floor smoothing underlayment was used over a Stopgap Waterproof Surface Membrane, firstly to build up the subfloor to the required thickness and then create a smooth, durable surface on which the final floorcovering could be laid. Styccobond F46 pressure sensitive acrylic adhesive was used to secure the vinyl Polyflor XL floorcovering to the finished subfloor...

Koster Aquatecnic were approached by the project architect to assist in a specification to renew the waterproofing to the roof of the large visitor cottages at the base of Ardnamurchan Lighthouse.This lighthouse is situated at the most westerly point in the British Isles and as such is extremely exposed to the elements. A robust material and system had to be produced. This was a very challenging project and a great deal of assistance was provided including bespoke drawings, office and site meetings followed by leak testing services to ensure fully watertight.Please read through the case study and if you have any questions or would like advice on a similar project, please contact technical@kosteruk.com.

Thames City is a spectacular location and presence in Zone One of the River Thames. With some of the city’s most breathtaking views, especially for those not afraid of heights, this is a fresh district featuring three residential towers, a development of 12 buildings, beautiful apartments with private luxury amenities, high-end retail, and fine dining venues.The overall experience of this amazing project is made even more appealing thanks to its network of interconnecting parks, cosy green courtyards, and romantic city squares.This project was complex, involving both TerraSmart Rail Paving and TerraSmart Pedestal Paving Systems. Both these systems are designed for waterproofed substrates with TerraSmart Rail being the ultimate raised paving system, unbelievably solid thanks to its unique lattice framework.Due to the height of the tower, we worked closely with Midgard Design Services to develop and install an appropriate wind uplift mitigation solution to keep the project within budget.The TerraSmart Rail Paving System was weighted using ballast weights, and installed in the joist frame to mitigate uplift – it couldn’t be fixed into the structural slab due to it being an inverted roof. The pavers were then mechanically fixed to the joists using a wind uplift visual fixing, which clamps down the entire system.The TerraSmart Pedestal Paving System was mechanically fixed to the structural slab as there was no waterproofing membrane to penetrate underneath. The wind uplift mechanical fixing was screwed into the top of the pedestals to retain the concrete pavers and prevent any movement in strong winds.The installation of the systems was beautifully done by ANC Construction and the proof is in the photos you see on our website.

Ghelamco Arena CHALLENGE Ghent’s football club, KAA Gent, had big ambitions – having a big stadium was one of them. Its brand new home was built in order to seat more spectators and take the club to the top of the Belgian league. As the first newly-built stadium in Belgium since 1974, the multi-use Ghelamco Arena opened its doors in 2013. The stadium hosts - besides KAA Gent matches - a multitude of events throughout the year, as well a gym, supermarket, office facilities and a Guide Michelin restaurant. It’s located near the historical centre of Ghent, just outside the city. The arena, which seats 20,000 supporters, is one of Europe’s most modern stadiums. A stadium specifically designed for the ultimate football experience! How could RENOLIT help make the new stadium a success?SOLUTION The Ghelamco Arena is a real eye-catcher: impressive, fashionable in design and an architectural beauty. The stadium, however, is more than just design, it is above all environmentally friendly. The stadium was constructed with considerations towards its ecological footprint and as a result, the roof was made waterproof by means of the ecological, reflective RENOLIT ALKORBRIGHT waterproofing membrane. This completely white roofing membrane, together with the special protective coating on top of the membrane ensures a high reflection of the sunlight, which in summertime has a positive impact on the climate inside the building. With an initial reflection of 90%, the RENOLIT ALKORBRIGHT concept can consider itself to be at the absolute top of the “cool roof” roofing membranes. 

One of Cardiff city centre’s recent regeneration schemes, Capitol Quarter, required a multi storey car park to provide parking for the new office buildings within the development. To ensure the car park was protected and finished with the highest quality materials, the main contractor sought advice from Degafloor Ltd to ensure a suitable cost effective, high performance waterproofing system for the top deck, ramp and an inter deck area over occupied premises was specified. Following a full site visit and having assessed the client’s requirements in full, Degafloor specified the CP TD system with fleeced banding to substrate cracks and all upstands for the top deck, the CP HD system for the ramp and a fully fleeced CP TD for the area over occupied premises. Capital Quarter Multi-Storey Car Park Cardiff Why Degafloor Degafloor car park decking systems use highly advanced fast curing MMA chemistry to create flexible and incredibly durable systems that cure fully within just 1 hour of installation, even at temperatures as low as -10°C. They are completely waterproof, so guard against water ingress that could result in the decline of structures or damage to property (premises or vehicles). This combination of superior performance, skid resistance, rapid cure times and design flexibility, have contributed to the Degafloor range of car park decking systems becoming a popular choice for new build and refurbishment projects where speed and ease of installation, longevity and visual aesthetics are paramount.

The UK’s second busiest airport, Gatwick Airport, is also home to a rail station which handles in excess of 20 million passengers annually – making it one of the 10 busiest stations in the UK outside of London.Network Rail are currently managing a redevelopment project at Gatwick station, which is being delivered by Costain. Part of this project is a new concourse for the station.The redevelopment of the station includes improvement works to create a larger, more accessible interchange between the station and airport. As part of the upgrades to platforms 5-7, Costain worked with Sika waterproofing products and Hanson for the concrete mix to ensure the rebuild was robust and would offer significant longevity.

This 115m² project was a large luxury new-build. The decking required two distinct build-up methods around the house. One section was on a waterproofing membrane, the other on a steel framed walkway. Adjustable support pedestals were loose-laid onto the membrane. iDecking aluminium rail system was set onto the pedestals and EasyClick boards were clicked into place. Pedestals lifted the decking structure off the membrane allowing free drainage and creating a level surface on the falling roof. Aluminium rails were mechanically fixed to the steel structure and the whole terrace was set to one, seamless level wrapping around the house.

Completely restructured, the building is BREEAM Good, certified by BBC Effinergie Rénovation and HQE Rénovation Très Bien.

Nearly 1000 metres of T-Pren gutter expansion joints were installed on the 28,000 sq.m. curved roof the Rocky Ridge recreational centre in Calgary, Canada. The wide curved gutter required long special lengths of T-Pren, 9-18m long, and were installed in pairs to provide double the expansion movement. T-Pren forms a waterproof expansion joint, which eliminates the standard step detail and so reduces the number of rainwater outlets required. T-Pren is a composite material made from neoprene and metal bonded under controlled factory conditions to ISO 9001 quality standards.

The Tate Modern’s Switch House is a new pyramid-shaped tower is built above the former power station’s subterranean oil tanks. The extension, which can be seen as you approach from the north, comprises ten floors that become incrementally smaller towards the top of the tower and culminates in a spectacular public roof terrace. Visitors to the roof are rewarded with 360-degree views of the river Thames, St Paul’s Cathedral and the London skyline, and you can see as far as Tower Bridge, the Old Bailey and Wembley Stadium.Radmat Building Products supplied a waterproofing solution to roof and viewing platform on the newly opened extension.

Stopgap 800 wearcoat has been used to create a visually striking floor finish at a new organic meat restaurant in South London. First, contractors lifted the old wood floorcoverings to ensure it was suitably sound, smooth, and dry. To guard against excess subfloor moisture, contractors applied Stopgap F77 waterproof surface membrane to isolate excess subfloor moisture. Stopgap 800 Wearcoat was then applied over the entire subfloor. Stopgap 800 was selected due to its capabilities when it comes to upgrading and renovating new and existing internal floors, where floorcoverings are not required to be installed, making it perfect for this project.

Fast-track products from F. Ball have enabled a school hall to be refurbished after damage caused by floods. To begin with, contractors removed existing wooden blocks from the floor and used a mechanical scabbler to remove old adhesive residues. Stopgap F77 one-part waterproof surface membrane was applied due to high moisture levels in the subfloor, followed by a subsequent application of Stopgap 1200 Pro to provide a smooth surface for the receipt of new wooden floorcoverings. Once cured, contractors used Styccobond B95 high performance wood flooring adhesive to install new oak blocks over the entire floor area.

The designer obtained consent under the latest SuDS regulations in the densely build area of London. Restriction on outflow rates to sewers demanded high attenuation. The original design for stormwater attenuation involved discharging tanks under the ground. This was expensive and took up valuable space, an alternative was required. ABG proposed their Blueroof system which could be installed directly on to the hot melt waterproofing system allowing various surface finishes. Due to height limitations a cascade system was used. Various roof finishes included paved access, landscaped areas and bio diverse to attract wildlife. This increased the potential for BREEAM points.

A three year construction project in Knightsbridge required a temporary green roof on welfare huts. The local residents were concerned about overlooking these steel huts long-term. The solution is M-Tray® – our modular green roof system. The steel huts were wheeled into position on site on skates. They were covered with an EPDM waterproofing membrane. M-Tray® units were installed. They were easily carried up the stairs by hand and installed by hand within minutes. The modular and portable M-Tray® can just be unclicked and lifted away upon completion of the construction process.
