Abstract : To achieve successful and durable bituminous waterproof membranes the designer must consider the properties and behaviour of both bitumen and reinforcement, the nature and behaviour of the surface to which it is applied, and the conditions of exposure or properties of the environment in which it must serve. The composite membrane has certain desirable properties, but is subject to several mechanisms of deterioration that can be allowed for or guarded against by design. The protection or shading of a membrane from solar radiation (CBD 65) has great value in extending its life, as does provision for drainage and the avoidance of trapped moisture. In some cases the occurrence of membrane failure can be prevented by a planned program of periodic maintenance. The manner of installation and quality of workmanship, however, are of fundamental importance to the performance of bituminous membranes. (Author)
