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.

Since 2015, the Fresno Area Express (FAX), operated by the Department of Transportation in the City of Fresno, California, USA, has undertaken three separate major capital improvement projects, which have been implemented to improve services to the city’s many public transit users.

Low environmental impact... CHALLENGE All over the world architects and building owners are trying to create buildings with a low environmental impact. For this private house, the architect wanted to combine an aesthetical finish of a metal roof in combination with PV and hot water panels. The biggest issue for the architect was the fixing of these panels without having leak problems in the future. SOLUTION The roof was waterproofed using a RENOLIT ALKORPLAN roofing membrane that is mechanically fastened onto the supporting roof structure. Two kinds of PVC profiles were heat welded onto the waterproofing membrane: on the one hand RENOLIT ALKORDESIGN profiles (for aesthetical value only), on the other hand there are RENOLIT ALKORSOLAR profiles, which function as the base to attach the hot water and the PV panels. The gable was also finished with the RENOLIT ALKORDESIGN system.

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.

Originally built over 200 years ago, the revamped Spitfire Studios now combines commercial office space with eight residential apartments.

To facilitiate their exciting BSc Paramedic Science course, the University of Surrey identified that they needed more practical training space for their students. By working alongside Scott Brownrigg Architects, Newton Specialist Contractor Advanced Basements, and the Newton Technical Team, an extensive existing undercroft was converted into three large, dry rooms that are ideal for the purpose.With an emphasis on practical elements, the exciting BSc Paramedic Science course at the University of Surrey needed a new, well-equipped training facility for its students at the Surrey Research Park, Guildford.Having identified a large existing undercroft for the purpose, the University consulted with Scott Brownrigg Architects, as well as the Newton Technical team and Advanced Basements in order to create a new, dry space.The extensive undercroft area was first separated into three large rooms, based on what each room was going to be used for. These were defined as:A live environment Paramedic Training room, with an existing concrete floor, concrete retaining walls, and blockwork internal wallsA storage area, requiring a new insulated floor, and with concrete retainng walls and blockwork internal wallsA plant room, requiring full internal waterproofing to the walls and floorConsidering that the existing structure was already quite robust, Newton and Advanced recommended an internal Type C Newton CDM System. This method of waterproofing is the most failsafe method, using membranes to capture the water, and sump chambers and pumps to collect and remove it. The pumps are also supported by a battery backup system for total security.Advanced Basements acted as the specialist waterproofing contractor and the waterproofing design specialist on this project, working alongside the architect and client to design the system, before providing a high quality installation.Furthermore, thanks to their early involvement, Advanced also took design liability for the project and guaranteed the installation for the client.

This project, built by Ashe Construction, has been designed to comply with the Passivhaus standard. The main structure is Cross Laminated Timber (CLT) and has been protected from the elements with Pro Clima Solitex Adhero, a weatherproof self-adhesive breather membrane and rain jacket for the building.

Safeshield XT Reflect A2-s1, d0 fire rated wall membrane was used in the recladding of the Genting Casino, Premier and Holiday Inns.RIVERLIGHTS DERBY, MORELEDGEA complete re-cladding on the exterior of the Genting Casino, Premier Inn, Holiday Inn, part of the Riverlights location in Derby city centre, including Safeshield XT Reflect A2-s1, d0 fire rated construction membrane.Oakleigh Contracts were chosen to undertake this large-scale project, their first re-cladding project of this size, with technical input from Permavent to ensure the correct technical specifications were achieved. 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.

Jubilee Bridge was constructed in 1977 - chloride contamination was causing corrosion of the suspended and cantilever reinforced concrete support beams, half-joint elements and the soffits of the beamsICCP was used to protect cantilever beams, half-joints and suspended slab elements. Over 8,500 anodes were drilled in and are controlled in 20 zones with separate control of the beams and the half-joints.

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.

The curved teaching space and the auditorium block are connected by a curved segment known as ‘The Link’ which runs through each floor of the building. This linking component features Schüco FWS 50 curtain walling both in the construction of the walls and horizontally in the roof skylights to let natural light into the centre of the building. The Link also acts as an important device to separate the two geometrically opposed buildings.

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.

Achieving a Building Regulations compliant level of soundproofing in residential conversion projects demands the use of superior quality soundproofing materials and systems, which are deployed in the right way. It is an approach that a recent development in the south Manchester suburb of Levenshulme perfectly encapsulates, with outstanding results for the developer and future residents.Hush Acoustics was tasked to provide a solution for a conversion project at 31 Albert Road, Levenshulme by Meridian Construction & Refurbishments. It was converting the five-bedroom Victorian dwelling into two residential flats, which meant the separating floors had to be constructed in a way that would meet the acoustic standards set out in Approved Document E of the Building Regulations for England and Wales.Under Approved Document E, ‘material change of use’ projects like this must incorporate soundproofing in the floors between individual dwellings to reduce the risk of nuisance sound transmission. Evidence that the floor construction complies with the standards is normally provided to building control through post-installation acoustic testing, which on this project was undertaken by C80 Solutions.Hush Acoustics was invited to attend the site by Meridian when the building was at its early rip out stage. This provided an opportunity to get a clear understanding of the situation and discuss the options for the separating floors to ensure they would meet the requirements of Approved Document E.The floor structure was a traditional timber floor with floorboards. There was only a very limited specification in the design, so Hush was able to help by providing specialist technical consultation to develop the most cost effective and easy to install solution for the Meridian site team.Following the site visit and inspection of the building, Hush Acoustics’ soundproofing specialists developed an acoustic product specification for the separating floors that would not only meet the minimum standards of the Building Regulations, but exceed them with ease.Hush-Panel 17, a thin MDF overlay board which incorporates a 10mm Hush-Felt resilient layer, was installed over the structural deck. This was glued using Hush-Bond Panel Adhesive and isolated at the perimeters using Hush-Seal 20.The structural deck consisted of the original floorboards that had been overboarded with a thin plywood. This provided a solid flat surface to install the acoustic flooring. The existing ceiling was left in place where possible to avoid the need for ripping out where it was not required, which allowed for a new acoustic ceiling to be installed. This consisted of two layers of 15mm Fireline plasterboard on a suspended frame with Hush-Slab 100 sound absorber slabs placed within the ceiling void.As part of the service, Hush Acoustics arranged for the acoustic testing to be carried out by testing partner C80 Solutions. They recorded the following results:Airborne – 53 dB DnTw+Ctr and 52 dB DnTw+Ctr (the higher, the better)Impact – 48 dB LnTw and 43 dB LnTw (the lower, the better)These are very good acoustic figures for a separating floor in a residential conversion project of this kind, demonstrating what can be achieved with a combination of high quality soundproofing materials are combined and installation correctly.Ultimately, this outstanding acoustic performance for the separating floors will help to ensure a high level of satisfaction for the future residents of these modern apartments.

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.
