Pre Applied HDPE glue releasing film/granules Self Adhesive Membrane for Underground Waterproofing

Pre applied HDPE sheet self adhesive with sand adopts high-density polyethylene (HDPE) as the main waterproof layer, which is composed of self-adhesive layer, protective layer (for environmental change), and isolated layer. The self-adhesive layer and protective layer have self-healing function. This waterproof membrane reserves a 70 mm wide self-adhesive overlap edge on the long side. After its reaction with liquid state concrete mortar, a seamless combination between the waterproof layer and concrete structure is achieved, which improves the reliability of the waterproof system. This HDPE self adhesive waterproof membrane has found a wide scope of applications, and is widely applied in underground projects.

High-density Polyethylene (HDPE) Self-adhesive Waterproof Membrane is specially used in underground project, it can bond with concrete layer tightly. After Membrane bonding with concrete, water can be blocked between membrane and concrete, which can improve the reliability.
