Waterproof board, also known as geomembrane, is commonly referred to as waterproof board for geomembrane with a thickness of ≥ 0.8mm, and geomembrane for geomembrane with a thickness of<0.8mm. It is a type of anti-seepage material made of polymer as the basic material, divided into homogeneous waterproof board and composite waterproof board. It is a type of anti-seepage material made of polymer as the basic raw material, which can prevent liquid leakage and gas volatilization.
1. Excellent flexibility, impermeability, elongation, and wear resistance;
2. Has good isolation and puncture resistance;
3. No chemical pollution;
4. Resistant to acid, alkali, and various chemical substances, with good dimensional stability and adhesion, making it easy to construct.

Due to its high physical and mechanical performance indicators such as tensile strength, tear resistance, and bursting, the product has characteristics such as high strength, good elongation performance, large deformation modulus, acid and alkali resistance, corrosion resistance, aging resistance, and good anti-seepage performance. It can meet the needs of civil engineering such as seepage prevention, isolation, reinforcement, crack prevention and reinforcement in water conservancy, municipal administration, construction, transportation, subway, tunnel and engineering construction. Due to the use of polymer materials and the addition of anti-aging agents in the production process, this waterproof board can be used in unconventional temperature environments. It is often used for anti-seepage treatment of embankments, drainage ditches, and waste disposal sites.
