If the owner chooses the half-package or all-package decoration mode, he needs to buy the decoration materials himself. If he hadn't touched some decoration materials before, he wouldn't know what waterproof coiled material is. Knowing that it is used for indoor waterproofing, some people plan to buy it for indoor decoration. How to choose waterproof coiled material is discussed in the following small series.

Function of waterproofing membrane

Waterproof membrane is mainly used in roofs, roads, tunnels, building walls, landfills and other places, which can resist the leakage of rainwater and groundwater. As a leak-proof connection between the engineering foundation and the building, it is the first barrier of the whole project and plays a vital role in the whole project.

Types of waterproofing membrane

Products mainly include asphalt waterproofing membrane and polymer waterproofing membrane. Asphalt waterproofing membrane includes body shaping (APP) modified asphalt waterproofing membrane, elastomer (SBS) modified asphalt waterproofing membrane and asphalt composite tire flexible waterproofing membrane.

Matters needing attention in purchasing waterproof coiled material

1, packaging logo: We need to pay attention to the trademark, product logo, manufacturer's name, production date, etc. On the packaging, we need to see it clearly. In addition, it should be noted that the storage period of coils is generally not more than one year. 2. Look at the tire base: tear the edge of the coil by hand to see if the tire base is consistent with the mark and completely saturated. There should be no unsaturated white marks or spots on the bottom of the tire. If they appear, the quality of waterproofing membrane will be poor.
