Durham University Gateway

Durham University Gateway

Polyroof Products Ltd

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.

Queens Crescent, London

Queens Crescent, London

Polyroof Products Ltd

Queens Crescent is a bustling retail street situated in London’s Kentish Town. The roof area above the Post Office building, which also served as a communal walkway area with access to the upper level of the adjacent buildings, had been suffering from leaks. To add to the issues, the aged promenade tiles had worn and become a slip hazard when trafficked. Looking for a lasting waterproof solution that can also provide heavy duty anti-slip surfacing, the client turned to Polyroof for a solution. To minimise access disruption to the upper level adjacent buildings, the client had organised a 5-day window for the waterproofing and surfacing works to be completed.The SolutionThe main contractor had removed the old paving slabs and membrane back to the concrete deck underneath and carried out repairs to create a level surface.Approved Polyroof Contractor Emperor Roofing began by priming the concrete surface to create a sealed, non-porous substrate. With its quick-curing properties, the Polyroof primer was ready to be over-coated only 30 minutes after its installation.A specialist twin-pack epoxy metallic primer was applied to metal detailing sections, including ducting vents and the intricate balustrade detail alongside the communal stairwell, which also formed part of the specified works.Local reinforcements were carried out to these details involving taking Protec resin and PolyMat 450 up by 150mm before applying the full waterproofing system.Upon completion, the balustrades were re-painted, with the paint being taken over the waterproofing membrane to create a neat detail. A key advantage of liquid systems in general is their ability to seamlessly seal around complex detailing; in this instance, quite simply, the balustrades could not have been sealed effectively using a traditional waterproofing technology.Polyroof’s Protec System enjoys exceptionally fast detailing speeds, where its formulation allows it to rapidly break down the chopped strand mat reinforcement and neatly moulds around the detail it is covering. To the left of the stairwell, the Protec system was chased in at a height of 150mm above the level of the stairs.The termination point of the waterproofing membrane was sealed with mastic to create a fully weatherproof detail. The Protec system was dressed onto the wall abutments to the main areas but left self-terminated as new render is to be applied to the walls and taken down over the top of the Protec system.After local reinforcements were completed the main waterproofing system was applied to the walkway and stair areas.The two-coat Protec system was able to be rapidly installed with its 30-60 minutes cure times, meaning the project was comfortably ahead of schedule by the time it was complete.Next, the designated anti-slip areas were carefully masked off, leaving the exposed waterproofing to the roof perimeters, detailing and vertical sides of the step and stairs. A third coat of Protec was applied to the masked sections and, whilst the liquid was still wet, 0.7-1.2mm quartz sand aggregate was broadcast into the resin.Once dried, the aggregate is embedded within the membrane and lose sand was brushed off and collected to be re-used. In order to provide an extra-tough surface that sealed that aggregate in place, a coating of PolyFinish was applied over the aggregate in the client’s choice of light grey.

Canterbury Riverside Square B11-13 Car Park Case Study

Canterbury Riverside Square B11-13 Car Park Case Study

Fosroc International Limited

THE PROJECTCanterbury Riverside is a major new residential development designed by PRC Architecture for Bouygues Development\Link City. Its construction has been in progress since 2020, and in January 2022, the main contractor for one of the housing elements, Jenner Ltd, commenced work on the below-ground Block 11-13 car park. Jenner appointed specialist contractor GSE to install a new ground bearing slab within the car park, which would tie in with existing columns and retaining walls. The dimensions of the slab required movement joints to be accommodated and there were multiple access points that required waterproofing detailing. The design and installation was also required to meet the requirements of the NHBC (National House Building Council), so Fosroc was appointed to supply materials, and Waterproofing Design Services to carry out the design work. Jenner had previously worked with both Fosroc and WDS on block 14 of the project to provide gas resistant membranes and design.THE SOLUTIONSupercast Crystalline Waterproof concrete was selected due to its robust waterproofing response to any potential ingress through the ground bearing slab. Supercast PVC waterbars were also installed at every movement joint, with the complete Fosroc joint solution installed via Hydrocell XL closed cell compressible joint filler and Nitoseal MS300 joint sealant, which protected the joints against damage from traffic. Care was taken to design a fully linked waterproofing system around the joints between the new slab and existing column bases. This element was closely coordinated with the installing contractor (GSE).THE BENEFITSPour sizes and schedules were optimised by careful design and coordination. A flexible and fully watertight solution was achieved, and regular dialogue with the installing contractor ensured obstacles were swiftly overcome. Feedback from GSE was positive, with Site Manager Darren Knight commenting “This was the first time we had installed the FOSROC products on a waterproof detail. The advice and the back up from the team was very good and Paul Hitchins was on hand all along the install route to aide any issues, promptly answering our questions. The products were easy to install, and regular on-site inspections ensured a smooth install throughout. I would have no issue installing this product on any other job when specified.”

Royal Russell School

Royal Russell School

Danosa UK Ltd

The Royal Russell School in Croydon demonstrates the vast variety of waterproofing applications with which DANOPOL membranes can be specified. From standard flat roof areas to pitched standing seam roofs, vertical applications and accessible terraces, the flexibility of specification is really showcased on this project. The most noticeable feature is the stunning standing seam roofs, which are also DANOPOL HSF+ membrane, completed with ALPHA PROFILES. These ALPHA PROFILES are raised PVC profiles made from DANOPOL materials which can be retrospectively heat welded to the surface of the completed waterproofing system. The use of Alpha Profiles is rapidly increasing as the design may be highly customised and the installed centres can be changed to suit a clients particular aesthetic preferences and are often installed to obscure any standard membrane overlaps. An advantage of selecting DANOPOL membranes over a traditional metal standing seam roof option is that at less than 3.00kg per m2 for the waterproofing membrane, the system is incredibly lightweight and may be installed onto many lightweight structural substrates. The reduced load, when compared to traditional standing seam roof options, can also translate into savings on the underlying supporting structure. Our DANOPOL+ HSF membrane was also utilised on the terrace areas, which included vertical detailing to clad the internal faces of the parapet walls, providing a fully-encompassing watertight finish to the roof areas. Waterproofing System: DANOPOL+ HSF 1.5mm - Dark GreyConstruction Type: New Build Warm Roof Sector: EducationApprox.

The Pride development is a £60 million investment which includes a new 122 bed hospital being built on the former Ryhope Hospital site in Sunderland. Laing O’Rourke, the main contractors of this project, specified Polyroof waterproofing systems for the flat roof areas.Barclay Roofing Ltd carried out the works, having previously worked with Laing O’Rourke on the 2013 Roofing Award Winning Durham Gateway Project.The SolutionThe roofs were of a complex nature and involved many details such as vents, level changes, handrail abutments, plant supports, protrusions, stanchion blocks, and parapet walls. It was essential that these details could be waterproofed in the most effective and rapid way possible. Protec, being liquid-applied, was dressed onto the upstands of the details without the need for lengthy and complicated ‘patching’ work, creating a totally seamless interface between the details and the flat roof membrane.The client required designated, permanent walkways for maintenance purposes. Quartz Sand & Polyfinish was used to create a durable and hard-wearing anti-slip finish, without the need for costly ancillary walkway systems. The system is capable of withstanding heavy foot traffic and is impact resistant meaning the client had peace of mind that the walkways can be used without the risk of damaging the waterproofing integrity. Some of the roof areas are to be covered with a green roof system. The waterproofing membrane that was used therefore had to be highly durable, lightweight, fully root resistant and maintenance-free. The Protec System meets all the criteria for use with green roofs and was specified as the ideal solution for the green roof areas.It was essential that health & safety and hazard risks were kept to an absolute minimum during works. Being cold applied and low in VOC content, Protec was able to satisfy the stringent requirements of this aspect of the project.Due to the size of the roof areas, structural expansion and contraction movements had to be considered. Ideally the client wanted a waterproofing system that could accommodate these movements without the need for any additional and potentially costly modifications such as expansion joints. Protec is specially formulated to be highly flexible whilst also maintain its durability and hard-wearing properties.

This required our installations teams to make repeated visits to site, using both internal and external hoists for access; with work completed in March 2014.”“The inverted roof arrangement means the waterproofing is covered by insulation and either paving, ballast or planted medium,” he added. “Then there is also the sky garden at an angle of 45 degrees planted with trees and shrubs, which will be accessible to clients using the restaurant there.”For public-access terracing across levels 34-38 – as well as a series of applications on the Ground Floor, second floor and the concrete staircase – over 1,200m² of Radmat PermaQuik PQ6100 was applied. With an independently verified durability ‘for the lifetime of the building’ and a market leading guarantee, the liquid-applied PQ6100 waterproofing system delivers exceptional performance befitting of this unique build.On level 37, where visitors can enjoy 360° views of the capital, additional waterproofing was required following the installation of a glass internal cladding system. With the glass already in place and challenged by high winds and low temperatures, the fast curing, cold applied ParaFlex waterproofing system was specified. Suitable for application at temperatures below zero reliable sealing can even be achieved at -5°C. Utilising collaborative working practices and a responsive and interactive design process, Radmat have created a stunning waterproofing and green roof application of the highest standard. Radmat’s proven range of waterproofing solutions met all the client’s demands and has ensured that visitors from all over the world can enjoy this stunning venue for many years to come.

Polyroof Products Ltd

The Castle Cove Sailing Club in Weymouth, Dorset, constructed a new terrace area to provide a viewing platform for the sailing events in the London 2012 Olympic and Paralympic Games.The sailing club required a waterproofing system that could be installed directly to the concrete construction in order for the works to be completed as quickly as possible. It was essential that the system was compatible with timber decking and would provide long-term protection from the elements.The sailing club contacted KG Roofing, their local Polyroof Approved Contractor, to provide a waterproofing solution that could meet the demands of the project. The BBA-Approved Protec System was specified for the works due to its rapid cure times and high waterproofing performance. Timber battens were incorporated into the system to create fixing platforms, creating a striking yet functional support for the timber decking and glass balustrade.With the Protect System affording rapid curing times, the terrace was finished within the desired time-frame, leaving ample time before the beginning of the Olympic Games. The lucky viewers at Castle Cove Sailing Club witnessed many record-breaking performances from Team GB’s sailing team, including Ben Ainslie becoming Britain’s greatest ever Olympic sailor.
