How to correctly select building self-adhesive film waterproof coiled material

The self-adhesive waterproof coiled material for construction is mainly used for building walls, roofs, tunnels, highways, landfills and other places. It is a flexible building material product that can be curled into a roll to resist the leakage of external rainwater and groundwater. As a non leakage connection between the project foundation and buildings, it is a waterproof barrier of the whole project and plays a vital role in the whole project. The main products are modified asphalt self-adhesive waterproof coiled material and polymer self-adhesive waterproof coiled material.

Self adhesive waterproof coiled material

1. Look at the tire base. The method of tearing the edge of the coil by hand can be used to judge whether the tire base is consistent with the mark, whether it is completely soaked and meets the requirements specified in the standard. The tire base shall be free of non soaked white marks or light spots. Polyester tire is difficult to tear and break by hand, and asphalt has good affinity with the tire base, while asphalt composite tire coil is often easy to tear, and the tire base can be observed by tearing.

2. Determined by physical performance test. The cut 0.8m coil shall be tested for physical and mechanical properties according to the standard, and it is qualified if it meets the standard requirements.

3. Package identification. The above three material lists are not very different from each other in appearance. Therefore, we should first see whether the packaging and identification are standardized. The marks shall indicate the manufacturer's name, trademark, product mark, production date or batch number, production license number, storage and transportation precautions. Each coil shall be marked in strict accordance with the sequence specified in the national standard.
