Trinity Buoy Wharf, London Docklands


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 togther, creating an innovative modular building solution that houses a 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 now occuring…

Large Shopping Centre, Newcastle


The Protec system has waterproofed vast areas of the roof of one of the largest shopping centres in the UK, which were in need of refurbishment as they had been persistently leaking for some time. A quick and effective waterproofing solution was needed that would allow the day-to-day running of the shopping centre to continue without any disruption for the customers, which could prove extremely costly… [Read more]

 


Gateway Project, Durham University


This project entailed a major expansion of Durham University and houses a variety of departments. The project was carried out to a BREEAM ‘Excellent’ Standard and as such only used components that had minimal environmental impact. 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… [Read More]

 


Grand Designs: Green Roof Project, Windermere


The Protec system was used to waterproof the domed green roof areas of this sustainable house development on Channel 4’s Grand Designs show. With an ambitious vision and a tight budget, Robert and Milla Gaukroger set about transforming an unattractive 1980’s house overlooking Lake Windermere into a state-of-the-art sustainable home. In order to blend into the hillside setting, the domed roofs of the house were to be covered with a wildflower meadow mix to provide a green roof construction… [Read More]

 


Monkwearmouth & Ryhope Hospital Developments


These new hospitals were constructed as part of the £60million Pride developments were built under the Trust’s NHS Procure21 Partnership, with several thousand square metres of roof areas requiring a long-lasting waterproofing system with high-performance insulation. Laing O’Rourke, the main contractors of this project, specified the Protec system for the flat roof areas. The ability of Protec to be installed quickly and efficiently minimised the time required for roof installations, meaning other trades could continue working as soon as possible… [Read More]
