"breather membrane"

HMS Caroline – Museum ship... CHALLENGE HMS Caroline, the last surviving vessel from the 1916 Battle of Jutland, now rests in the Titanic Quarter in Belfast. After a second life as floating Headquarters of the Royal Navy during World War II, this living legend will continue to serve the country as a museum ship. For this purpose, however, extensive restoration appeared to be essential. The key requirement on HMS Caroline was to avoid penetration of the deck surface. To safeguard its historic heritage against damage, the Royal Navy sought a reliable waterproofing solution. SOLUTION Versatile and impenetrable! What used to be the properties of this battle cruiser, happen to apply to the RENOLIT synthetic single ply roofing membranes as well. That’s why RENOLIT ALKORPLAN was heralded as the optimal solution for the refurbishment of the ship’s gun deck. The lead grey RENOLIT ALKORPLAN A provided an ideal modern day solution with an impressive finish. On top of a new layer of insulation board, the calendered and laminated fleece-backed PVC membrane was fully bonded with a combination of the RENOLIT ALKORPLUS81068 polyurethane adhesive and the universal RENOLIT DUALFIX81065 glue. RENOLIT ALKORPLAN stands out above the competition given its excellent weldability, simplicity of detailing and overall versatility. Once installed, ongoing maintenance of the membrane will be minimal with a predicted life expectancy in excess of 35 years (BBA approved). On 31st of May 2016 the freshly refurbished HMS Caroline stole the show as a fitting backdrop for a commemoration honouring its centenary. 

Modern materials were employed in the quest to recreate part of Bristol’s heritage. SIG Design & Technology supplied IKO’s Armourplan PSG single ply membrane because it fitted the bill perfectly as the roof covering was ideal for replicating the original seamed lead roof.

Genting Casinos are a large chain of popular gaming destinations with locations across the UK and America. The property owner of the Riverlights location decided to take no risks with their new cladding, in an effort to protect people and the building in the face of the recent issues with fire spreading through and behind exterior cladding. They chose to change the existing boards to non-combustible alternatives and added Safeshield XT Reflect A2-s1, d0 fire rated construction membrane to the walls under the new boards. Safeshield was chosen for it’s high fire rating, adding another layer of protection against fire behind the cladding and inside the cavity, but also for its superior thermal properties. Safeshield XT Reflect’s reflective technology allows for greater energy efficiency in the building as it reflects heat, decreasing the emissivity of the wall cavity and reducing energy loss. Oakleigh Contracts also praised Safeshield for it’s easy and intuitive installation, as well as being extremely robust both during and after installation

Considering the large size of the basement area and its proximity to the River Thames, Newton Specialist Contractor Stonehouse were called in to provide a complete waterproofing system for the structure.At this private property in South London, the plan was to build a new basement extending below the entire footprint of the house and into the rear garden, incorporating a swimming pool, recreational spaces and wine cellar.However, considering the close proximity to the River Thames and the high water table, Newton Specialist Contractor Stonehouse were called in to provide a complete waterproofing system for the entire structure.Considering the size of the basement area, the high water table, the geographical location close to the River Thames, and the fact that the structure was created using underpinning, the risk of water penetration in this basement was extremely high. Stonehouse recommended the most failsafe solution, the Newton CDM System.Firstly, they installed Newton 508 membrane to all internal walls and the floor, using Newton's ancillary products to fix the membrane securely and seal the system. Drainage channels were also created using Newton Basedrain, feeding into a sump chamber containing two NP750 pumps, a higher capacity model capable of dealing with large volumes of water.Finally, where the basement extended beyond the house's footprint, a liquid waterproofing membrane was used on the new external roof.Stonehouse is one of Newton's oldest and most experienced specialist contractors, and they showed their expertise here by delivering a dry, safe basement for the client that could then be transformed into a beautiful new part of their home. Furthermore, the installation was backed by Stonehouse's 10-year guarantee, for complete peace of mind.

The Durham Gateway project is a major new development at the Durham University that houses a variety of departments. Although aesthetically stunning, the concept presented several challenging issues.The project was carried out to a BREEAM ‘Excellent’ Standard and as such only used components that had minimal environmental impact. Cold-applied liquid roofing membranes, such as those manufactured by Polyroof, have been recognised by BRE to help roofing elements achieve up to an A+ rating (depending on the roof construction).Part of the works involved the construction of three curved roof areas that required a high-performance and durable waterproofing system which was to be covered by a timber shingle system. The shingles were supported by over 1,170 steel stanchions – all of which were seamlessly waterproofed with the Protec System.The main contractors of the project, Laing O’Rourke, were able to achieve the visual impact they wanted with the peace of mind that the roof was protected by a totally seamless and highly durable waterproofing membrane.

Find out why we recommend rafter ventilation slides when using spray foam insulation in pitched roofs where a high-resistance roof membrane is in place. The rafter slide not only provides ease of access to the external roof for future repairs/replacement, when ventilated appropriately, it can be effective at managing moisture.

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.

MJF Group completed the coating of Darlington Fire Station using RonaFloor HB200. The bays were completed using dark grey with the borders in brick red.

Waterproofing this historic London landmark – external waterproofing with Newton 403 HydroBond, internal waterproofing with Newton System 500, installed by Newton Specialist Basement Contractor MacLennanUK.Newton Waterproofing were delighted to return for this project at the prestigious Houses of Parliament in London, a landmark that has dominated London’s skyline for over 150 years. Newton Specialist Basement Contractor MacLennan Waterproofing was approached to specify a guaranteed waterproofing solution for the new-build basement.After reviewing the technical drawings, MacLennan decided to bring the job to Newton, whose product range was perfectly suited to the project requirements. Newton and MacLennan are both privileged to be the companies chosen to share in securing the future of the Palace of Westminster.This complex project required the design and installation of an external waterproofing system, an internal cavity drain system, and a polyurea roofing system to ensure a high standard of waterproofing.Externally, Newton’s innovative ‘Type A’ 403 HydroBond membrane was applied extensively to ensure the necessary waterproofing around the basement, whilst internally, Newton 508 and Newton 520 membranes were both applied from floor to ceiling as part of Newton’s complete System 500 cavity drainage solution. With the finished structure in place, the waterproofing was finally completed by the application of both a polyurea coating and further drainage membrane to the roof deck of the basement.With a waterproof basement fully compliant with the requirements of BS 8102:2009, coupled with guaranteed protection against water ingress, this newly completed, large basement area, situated directly next to the River Thames, provides a durable and well-established waterproofing solution, utilising multiple Newton Systems to great effect.

An impressive basement extension, housing a swimming pool and sauna, required a robust waterproofing solution at this large country home.Newton Specialist Contractor Stonehouse were brought onto this large residential project to waterproof an underground extension including a swimming pool and sauna. Set in a small village in Berkshire, the impressive countryside home was designed by architects Spratley and Partners.For the new below-ground structure, Stonehouse were required to install a failsafe and maintainable waterproofing system that would completely protect the luxurious basement from unwanted water ingress.Ensuring that the project was fully compliant with BS 8102:2009, Stonehouse recommended a combined waterproofing solution using a Type B reinforced and water-resistant concrete structure designed to BS EN 1992, combined with a full Type C internal cavity drain membrane system.As the most reliable and completely maintainable Type C waterproofing solution, the Newton CDM System was the ideal choice for this structure. Firstly, Newton 508 membrane was securely fixed to the internal walls of the basement using Newton's specialist MultiPlug fixings.Any water that is captured by the membrane is then drained away with Newton Basedrain channels, and pumped out of the property using a Titan-Pro sump chamber fitted with two NP400 pumps and supported by a failsafe battery back-up system.As an extremely experienced waterproofing contractor, Stonehouse were able to confidently recommend, design and install a comprehensive and truly failsafe waterproofing system that will protect the property from unwanted water ingress for many years to come. Stonehouse also provided complete peace of mind by offering a 10-year guarantee on the installation.

FOAMGLAS® Tapered T4+ (Slab)Design Architects: Renzo Piano Building WorkshopExecutive Architects: Adamson Associates, LondonMain Contractor: Mace; Roofing Contractor AC PLCConstruction: 2012Application: Warm Roof - FOAMGLAS® Tapered T4+ (Slab )Finish: Bitumen membranesFOAMGLAS® provided the ultimate solution for the roof maintenance platform of The Shard at level 75.Its light-weight and high compressive strength enable regular maintenance to be carried out without risk of surface damage.At 310 m, Shard Tower is one of Western Europe’s tallest buildings; exposed to extremes of temperature & the revolutionary structure sways up to 50 cm in high winds.The building maintenance platform on level 75 islocated directly above the viewing galleries, and essentially forms the Shard’s roof. To shed water, the flat metal platform required an insulation with a tapered top surface.In this extremely exposed location, and with significantloads upon the platform, a truly reliable solution was needed. FOAMGLAS® insulation combines compressive strength, long-term insulation performance.Using their "in house" CAD systems, FOAMGLAS® designed a bespoke Tapered Insulation system. Taking full advantage of its low coefficient of expansion, and to eliminate thermal bridging, FOAMGLAS® and its membranes were adhesive bonded onto the metal structure. The unique ability of FOAMGLAS® to withstand high compressive loads ensures regular maintenance work can be safely carried out without damage to the insulation or the membranes.Adamson Architects commented on this project: "FOAMGLAS® has proved itself to be the ultimate solution for the difficult loadbearing areas of the Shard. Specifying cellular glass insulation ensured complete integrity and performance in key areas of the Shard Tower".

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

Ghent Diamond CHALLENGE The Ghent Diamond is proudly overlooking the Ghent-Sint-Pieters railway station and surrounding neighbourhood. On top of a stonelike base with a pattern inspired by the city of Ghent’s historical architecture, an impressive crystalline edifice rises. The 33m high office building has – as the name indicates – not only the brilliance, but also the shape of a gigantic, polished diamond with numerous facets. The special design makes the building unique, and that is exactly where the difficulty lies: roof surfaces with different inclines, steep and hard-to-reach slopes, kinks in the façade and a serious wind load. On the pitched roof segments connecting the glass facade, an exterior roof finish with Linius RENSON blades is to be installed. Just for aesthetic reasons! Such a finish creates a nice play of light, shadow and reflection. But this can only be achieved if the finish has been executed perfectly! But how to execute the construction so precisely, and at the same time be perfectly watertight? A true challenge for both architect and roofing contractor. SOLUTIONFor the internationally renowned New York-based architects practice Asymptote this monumental Diamond project is just another jewel in the crown. Innovative and visionary, they always pursue extreme and experimental challenges. And yes, this impressive Diamond really was a challenge, especially for the Belgian ROTEAM roof experts. The special shape, the height and the different slopes up to 47° made it a complex, gargantuan waterproofing project. On top of the steel deck structure tongue and groove insulation panels were installed. This guarantees a strong, perfectly fitting and smooth construction. After all this is very important in order to achieve this monumental task. The high wind load and shear forces were decisive for the choice of roofing membrane to be used on this difficult structure. Asymptote architects therefore opted for the mechanically fastened RENOLIT ALKORPLAN F membrane. This PVC-P roofing membrane is specifically suited for such a project, thanks mainly to its flexibility, lightweight and long life.

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.

Koster Aquatecnic were approached to provide recommendations for sealing areas of heavy leakage in below ground sections within the vast basement.Given the type of construction, we designed a series of injection, Type A cementitious materials and Type C cavity membranes to protect the internal areas so they could be used by the hotel for storage, work areas and event spaces.

The National Gallery and the Science Museum - two of London’s major and iconic visitor attractions built more than 150 years ago – required an extensive programme of roof upgrades and maintenance. Working with the National Gallery since 1995, the roof replacement and thermal upgrading project has seen in excess of 12,000sq m of Sika Sarnafil membranes installed, together with insulation, roof lights and walkways in a series of over 30 completed projects – including the complete Sainsbury Wing in 2008.

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 a mixed-use development, planed by Marks Barfield Architects, creating 17 new homes. The purpose of this project is to promote the wellbeing of people, embracing circadian design principles. The building will include gardens and planting areas alongside office spaces, with a “forest floor” to the atrium spilling into the reception of the building. In this project Effisus Vapour FR Class A2 system was used to prevent the condensation risk, improving the airtightness and consequently the energy efficiency of the building, applying an A1 Vapour FR membrane.

Ulticolour, Tarmac's coloured asphalt was used to surface the redeveloped Promenade at Morecambe. The buff colour complemented the clean, modern design of the new sea wall.
