Compared with waterproof coatings, waterproof membranes have very good characteristics: such as convenient construction, short construction period, no need to maintain after forming, not affected by temperature, low environmental pollution, the thickness of the waterproof layer is easy to master according to the design requirements, and the material used is calculated accurately, convenient construction management, uniform layer thickness, and maintain the integrity of the waterproof layer even when large cracks occur in the base layer. Therefore, waterproofing membranes are more suitable for waterproofing construction of building walls, roofs, tunnels, highways, and garbage landfills.
