Extreme temperatures, rain, and freeze thaw cycles can all attack structures causing corrosion and therefore high maintenance costs. The UK DOT ensures maintenance is kept to a minimum by protecting its bridge stock using an effective waterproof coating which meets the exacting standards specified in BD47. A number of polyurethane based waterproofing systems have now met this standard. The inherent properties, ease of installation and long term protection offered by polyurethane systems make them extremely popular amongst client authorities across the world.
