"waterproofing"

Leafy Windlesham in Surrey was the location for this 5-bedroom, £15,000,000 mansion by Searchfield Homes, complete with a 4-metre deep basement containing a swimming pool and spa pool, all of which needed to be protected from water ingress and ground gases.

Newton CWC (Cold Wall Coating) Eliminates Condensation on the Internal Walls. It was installed on the internal walls in this pantry and eliminated condensation completely. Contains unique mineral powders which raise the temperature of the wall.

Newton System 500 fulfils all Listed Building requirements in this Georgian Manor House. Newton Pumping Systems installed to manage waste water, including two Newton Titan pumps and battery backup systems.

Newtons help defeat damp in this remarkable building using Newton System 800. Due to the age of the castle, there were significant rising and penetrating damp problems, for which Newton damp proof membranes were the ideal solution.

Battersea Dogs and Cats Home in London, the best-known animal sanctuary in the world, is currently undergoing the biggest development in its 154-year history - a £5 million scheme delivered by main contractor, Sir Robert McAlpine. The development will bring the charity’s existing buildings and facilities into the 21st century and will include a new build, state of the art veterinary hospital which will be protected by an innovative new waterproof membrane – Cold Melt® from Proteus – a seamless application designed to work in harmony with the roof infrastructure and so tough that it has been BBA certified to last for the lifetime of the building.Quality Control An integral part of this transformation is the built up roofing system of 1,200 square metres of Cold Melt®. Applied by the Proteus Licenced Contractor, a 5 layer built up system was employed to offer a bespoke specification tailored to the client’s needs and budget.The built up system consisted of a layer of Cold Melt® Proteus’ own innovative, cold-applied liquid membrane, over which an insulation layer of Proteus Pro-Therm XPS was laid. The Licenced Contractor then added a separator sheet of Proteus Low-K followed by an attenuation mat and then three different finishes in three different areas of the roof – paving slabs, a green roof and decking.Health & Safety Proteus’ liquid applied systems are cold installed and therefore negate all the elements of fire risk when working in confined spaces. Of particular importance was the low odour that Cold Melt® exhibits, meeting all the health and safety criteria necessary to protect both the Licenced Contractor’s operatives and the dogs and cats home’s residents.Long term performance Cold Melt® incorporates recycled rubber-crumb and other organically grown products and when covered, creates an elastomeric, seamless and cold applied membrane which has a life expectancy longer that the design life of the building on which it is installed.

The scope of this project was incredibly interesting. The owners sought to create a subterranean space which had the look and feel of a magical ‘Hobbit Home’ as if created by J. R. R. Tolkien himself.

The project was to convert a former vehicle maintenance and repair workshop into a dwelling. Ground tests did not reveal any significant level of Volatile organic compounds (VOC’s) in the soil but the local authority required a gas membrane to be installed and independently verified.

Dortek access solutions are built to withstand severe temperature variations and damp conditions, they are also bacteria and corrosion-resistant. Their timber free construction means they will not rot, rust or warp even after years of exposure to water and cleaning agents.

Built in 1855 as an Elizabethan School for local children, the historic and landmark Castle Club has also been a children’s hospital, youth club and private residence in its long history.Since being acquired by property developers Thackeray Group however, the Grade II Listed building is now to be converted and extended as a specialist care home.The work includes not only the restoration of the historic gothic structure, but also the building of a modern four-storey extension to the rear, including a 5,000-square-foot basement extension.

A brand new hospital in Middlesex will deliver efficient and much improved care to it’s patients. The hospital includes new wards, an extension on one of its existing wings as well as the relocation of its existing energy centre. With so much investment in the new hospital including state-of-the-art equipment, the roof design needed to be robust, provide security and require minimal maintenance throughout its lifetime.

Just a stroll away from The Shard, Schlüter-Systems provided wetroom solutions within the impressive complex for the luxurious Hilton London Bankside hotel and apartments.

The design concept of this project focuses on the demolition of an existing building and replacing it with a new build mixed use development of 6 storeys (plus basement) 9 self-contained units on floors 1-5 and 377sq m of commercial space on the basement and ground floors. During the Phase 1 Primary Risk Assessment, borehole and trial pits revealed Dibenzo (a,h)anthracene, CO², TPH and Asbestos contamination. The proposed remedial strategy to be adopted at the site was one of managing the pathway between the source of contamination and the critical receptors on-site.

Triton Systems supplied waterproofing systems specified by waterproofing design specialists, Ink Technical Services, for the upgrade to a below ground car park in North London. BS 8102 (2009) recommends the involvement of a waterproofing specialist at the design stage of any below ground waterproofing project. Involving an expert at this stage also minimises the risk of system failure in the future.

The contractor was relaying a waterproof membrane immediately above the London Aquarium and naturally the client was concerned about leaks with such precious livestock beneath. The waterproofing was torch-on bituminous felt membrane, due to be covered with road grade asphalt. Protecto-board was laid onto the waterproofing and secured with tape. It was cut to shape around the curbs cleanly and effectively without leaving vulnerable areas and without delaminating or crumbling, or leaching bitumen. It protected the waterproofing from temporary construction process damage and permanently protected it when covered with hot road grade asphalt afterwards

When Make Architects needed a waterproofing solution for their latest project in the City of London they turned to IKO PermaTEC hot melt. Waterproofing such an expansive and complex roof has its particular challenges and required robust and reliable detailing. The choice of waterproofing was to perform for a minimum of 30 years, be cost effective and also contribute towards the building’s design stage BREEAM Excellent rating.

Ronafix Pre-packed Screed 6-50mm was specified to be laid to falls to provide drainage to the new terrace construction, which provides access to student accommodation and waterproofing to the rear of the shop units below. Early application of the asphalt waterproofing was possible because Ronafix Pre-packed Screed 6-50mm dries faster than traditional sand and cement screeds, reducing the delay between application of the screed and waterproofing.

The multi-million pound refurbishment project saw the iconic building and its landscaped gardens restored to their former glory. Axter’s cold applied liquid waterproofing systems delivered a high quality solution to this challenging refurbishment.Systems in useStarcoat® QCStarcoat® PMMAKensington Roof Gardens is one of London’s best known venues, once famous for its flamingos and celebrity guests. The Grade II listed gardens were designed by landscape architect Ralph Hancock and date back to the 1930s. The venue features one of Central London’s most famous intensive living roofs and also includes an indoor restaurant, entertainment space and elevated terracing.ChallengesThe refurbishment of Kensington Roof Gardens was technically demanding. This was due to the complexity of the waterproofing details and space restricted installation locations as well as the specific waterproofing requirements.The refurbishment of the pond and waterways required a liquid waterproofing system that is proven to be safe for aquatic life, is UV stable and meets the aesthetic requirements. In addition, the waterproofing for the elevated terraces and walkways needed to be robust, rapid curing and appropriate for high traffic areas with a high quality, anti-slip finish.SolutionsAxter’s Technical Sales Team was able to provide BBA approved liquid waterproofing specifications for both areas. Axter ensured the highest quality waterproofing installation in all areas.Starcoat QC flame free single component PU resin waterproofing was used for the pond and waterways. The system cures fast in just 4-8 hours depending on the conditions and creates a tough, seamless, elastomeric membrane. This makes it ideal for complex refurbishment projects, such as Kensington Roof Gardens, where effective bridging of cracks and resistance to structural and thermal movement is essential. The robust, solvent free membrane also simplified the waterproofing of the site’s complex details and is resistant to chemicals and root penetration.The Starcoat PMMA (polymethyl methacrylate) two component waterproofing, used on the walkways and terraces, is zero fall accredited, hard wearing and can withstand significant loading and mechanical stresses. Available in a choice of colours, traffic and anti-slip finishes, it also provides an excellent solution for complex detailing and challenging application areas.AcknowledgmentsThe refurbishment of the iconic Kensington Roof Gardens demonstrates the versatility of our Starcoat PU and PMMA liquid waterproofing systems. Working closely with our partners, we were able to provide a high-quality technical solution that benefits from a 25-year system guarantee.Phil Wilcox Moore, Managing Director at Axter

This was a large roof terrace on a private domestic project. The area was flooded and had needed to be re-laid with waterproofing and a significant fall constructed into the deck to allow the often considerable amounts of rainwater to escape the roof deck. The contractor asked Wallbarn for a suitable but cost effective solution so we recommended Wallbarn 9mm rubber supports along with levelling shims. The area was re-waterproofed in the inverted waterproofing method, the membrane being covered with rigid insulation boards and a loose laid geotextile fabric to act as a separation layer .

Morris Blitz CourtBauder LiquiTEC cold applied liquid waterproofing systemSynopsisMorris Blitz Court is a residential housing estate in Hackney that has undergone an extensive amount of refurbishment works as part of the Decent Homes Programme. Included within the approved scheme was the renovation of all of the building’s balconies and walkways, as well as the transformation of the 1,000m2 concrete podium deck located above the car park into an aesthetically pleasing social space.Bauder Building BoardProject:Morris Blitz Court​Location:Hackney​Roof Area:1,400m²​Specifier:Mansell Construction Services​Approved Contractor:Armour Group​The specificationVarious waterproofing options were explored by the client, however, it was decided that the Bauder cold applied liquid systems would be the optimal solution given all the requirements.Project challengesOne of the major challenges for this project was the low door thresholds connecting to the podium deck, which couldn’t be raised, meaning that the build-up for the majority of the cold applied waterproofing and landscaping elements would need to be less than 100mm in height. Because of these restrictions the only drainage and protection board suitable within the system was Bauder’s Versicell 20, which is just 20mm in height but can withstand extremely high loading. The surface of the deck consists of three distinct finishes; permeable paving on the ground floor patios and walkways, artificial turf featuring fibreglass planters to serve as a communal garden and rubber mulch to create a play area for children.Balconies and communal walkways were waterproofed with Bauder’s cold applied reinforced waterproofing layer; which is extremely fast curing and can withstand foot traffic within an hour of being installed. Residents remained in situ throughout the installation so working hours were scheduled to accommodate for school hours. Despite the challenges encountered all works were completed on time and to budget. Products appliedBauder LiquiTEC SystemA cold applied liquid waterproofing system that offers the maximum versatility in roofing.

The project was split into 2 phases. Phase 1, waterproofing the exiting basement and Phase 2, retrofit extension to the existing basement to create a luxurious multiuse living area. Due to the partially retaining nature of the structure, the project required a combination of Type B and C waterproofing systems to ensure a Grade 3 habitable environment.

This project for Durham Lane Primary School saw the refurbishment of their existing roof. The previous bitumen waterproofing was showing signs of wear. Isolated areas of leaks had started to form, which was presenting classroom disruption.ChallengesFor funding purposes, the roof area was inspected and separated into two phases. Phase 1 of the roofing works presented a number of potential fire risks with combustible substrates and penetrations. The existing make-up performed poorly when tested against current building regulations.SolutionsFollowing minor remedial works, the existing waterproofing system was inspected and deemed suitable for use as the air and vapour control layer. Thermal and acoustic upgrades were introduced through the installation of Hytherm MW mineral wool insulation, ensuring building regulation compliance and an acoustically sound teaching environment in compliance with BB93.To complete the installation, Hyranger reinforced bitumen waterproofing system was installed, achieving a 20 year insured guaranteecovering waterproofing system materials supplied by Axter. In accordance with the NFRC’s Safe2Torch guidance, cold applied liquid waterproofing was required for detailing to fire risk areas; in this instance, Starcoat R was the system of choice due to uniform aesthetical finish and cost efficiency.Systems in useHyranger®Starcoat® R

A high profile residential development located on the derelict site of the once mighty Wimbledon FC, completed in 2008.OverviewAxter designed and supplied a complete structural waterproofing, insulation, drainage and landscaping solution to all elevated podia. The areas were intensively landscaped combining hard and soft finishes, creating a mixture of meandering pedestrian walkways and landscaped recreational gardens with a combined area of 6000m2.ChallengesThe primary challenge was to achieve a robust structural waterproofing system that could provide construction programme design, installation and cost efficiencies.A complex site drainage strategy, combined with multiple hard and soft landscaped finishes of varying depths, resulted in the need for additional drainage and water retention measures to be designed and implemented throughout the site.A high cost and varied landscaping design, with a relatively short seasonal installation time frame, demanded a waterproofing system designer and manufacturing partner that could meet these challenges.SolutionsThe design supply and installation of Wilotekt-Plus, unique second generation hot melt structural waterproofing system, provided 30% quicker on site installation speeds than traditional first generation hot melt systems. This ensured the waterproofing was completed swiftly, in excess of 500m2/day, which enabled landscaping finishes to be installed within deadline.The drainage strategy was simplified across all podia through the creation of a horizontal drainage zone above the waterproofing. Axter’s combined reservoir and drainage board was installed, retaining appropriate moisture levels for the specified plant requirements, whilst allowing excess moisture to drain freely away. It also acted as a permanent shutter for concrete works that allowed secondary structures to be built off these areas without contacting the waterproofing system or interrupting the drainage zone.Intensive hard and soft landscaping was completed by Frosts Landscapes Ltd using conveyor technology to distribute the soil and plants across the podia with ease.Systems in useWilotekt®-Plus

Sika supplied the waterproof solution to eliminate the threat of water ingress at an underground car park which houses a fleet of luxury cars.The car park, situated in Camden, North London, was subject to lateral moisture ingress due to ground water. It was decided to waterproof the affected area to safeguard a number of expensive cars regularly parked in a nearby designated bay.

UNIZO office building CHALLENGE Dedalus Architects specified zinc for waterproofing the timber frame UNIZO office building in Eeklo. Not only for the roof, but also for the facade and bottom side of a unique construction detail. To be precise, waterproofing horizontally, vertically and even upside down! To entirely cover the structure however, appeared not to be possible when using zinc. If you opt to use this traditional waterproofing material a ventilated air space must be provided underneath the zinc covering. This of course entails an opening for ventilation purposes underneath the roof edge, if not, condensation will occur. In the case of a building where the facade has to connect seamlessly with the roof and the underside, leaving an opening is not a possibility. So, despite the attractive appearance of zinc, a waterproofing solution with this material was not an option. SOLUTION Thanks to their collaboration with roofer ALBITUM and previous experiences with RENOLIT roofing products, Dedalus Architects came up with a nice alternative: RENOLIT ALKORDESIGN standing seam imitation. A perfect solution for a difficult challenge. No ventilation needed, no connection problems, the same looks as a zinc roof and, above all, more cost effective! 

Roof and facade cover... CHALLENGE For the design of a youth centre a Belgian architect wanted to have a fully homogeneous and waterproof cover for the roof and the facade. This envelope technique needed to be combined with a more ecological and aesthetically pleasing green wall design. SOLUTION For the waterproofing of the roof surface a standard RENOLIT ALKORPLAN roofing membrane was used. For the facades the architects opted for a RENOLIT ALKORSOLAR fixing system as the base to attach the final greenwall system. As the roof and the wall covering (waterproofing) are the same material there were no jointing issues. The whole building has been covered with RENOLIT ALKORPLAN roofing membrane. The facade details were similarly accomplished as standard roof details and RENOLIT ALKORSOLAR profiles were used to fix the rain water pipes from the roof.

Koster Flooring systems were used in the refurbishment of a hotel in London as a part of a complete basement waterproofing solution.Due to height restrictions, a waterproofing system and functioning vapour barrier with self leveled finish were required within a 10mm build up.

A particularly challenging element of the installation was the amount of intricate detailing requirements due to the elliptical shape and 5⁰ pitch of the wing areas. The waterproofing system needed to incorporate insulation that would achieve a 0.16 U-value and the memorial site had to remain open throughout the works causing logistical challenges.Bauder Building BoardProject:Battle of Britain MemorialLocation:Capel-le-FerneRoof Area:700m²Specifier:Godden Allen LawnApproved Contractor:Byford Roofing ServicesThe specificationBauder’s anthracite coloured Thermofol single ply system was specified because it is high-quality, long lasting and with the addition of welded roof profiles gives the appearance of a standing seam metal roof.The result The system build-up included Bauder’s 160mm PIR Insulation for superior thermal performance and all deliveries were timed as not to conflict with vehicles moving in and out of the facility.
