防水是建筑物的主要使用功能之一。防水材料的发展与应用,日益受到建筑设计、施工及使用单位的重视。柔性卷材防水经过多年来的工程实践,已经成为世界范围的土木建筑防水工程的传统做法。世界各国包括我国在内,半数以上的建筑防水工程采用沥青基浸渍卷材防水做法,其中使用数量最大的是沥青纸股油毡。 Waterproofing is one of the main functions of a building. The development and application of waterproof materials are increasingly valued by architectural design, construction and use units. After years of engineering practice, waterproofing of flexible coils has become a traditional practice in civil engineering waterproofing projects worldwide. Among all countries in the world, including China, more than half of construction waterproofing projects adopt asphalt-based impregnated coiled waterproofing practices, of which the largest number is bitumen paper stock felt.
