Following a major fire at the National Motorcycle Museum, the General Asphalte Company was immediately called in to discuss possible solutions to address the impending water ingress to the basement conference rooms/ballrooms. These sub terranian areas were previously protected by the rooms above – which were destroyed during the fire.The site comprised of a large 3,300 square metre concrete floor slab/basement roof deck. This area needed to be protected from the elements, until the Museum could be rebuilt, so that pre-booked conferences and functions could proceed.
In order to provide a waterproof surface, General Asphalte needed to apply a roofing grade asphalt. However, as it is a softer material than flooring grade asphalt, it would be unsuitable for foot traffic, or carpet, once the Museum was rebuilt.
General Asphalte’s solution was to liase with the asphalt manufacturer to devise a compromise specification. The softer waterproofing layer of asphalt was laid to a thickness of 10mm, which was subsequently covered with a 25mm coat of flooring grade asphalt. This allowed the surface to be used as a working platform for the re-construction works.
