The waterproof board is an impermeable material made of high molecular polymer as the basic raw material, which can prevent liquid leakage and gas volatilization. It is widely used in construction, transportation, subway, tunnel, and engineering construction.

Waterproof board is also called geomembrane. It is customary to call geomembrane ≥0.8mm thick as waterproof board, and geomembrane less than 0.8mm is called geomembrane. It is an impermeable material made of high molecular polymer as the basic raw material. Homogeneous waterproof board and composite waterproof board.

The waterproof board has a width of 4-6m and a weight of 200-1500g/square meter. It has high physical and mechanical properties such as tensile resistance, tear resistance and bursting resistance. The product has high strength, good elongation, large deformation modulus, and acid resistance It has the characteristics of alkali, corrosion resistance, aging resistance, and good anti-seepage performance.
