Waterproof plate is a kind of impermeable material made of high polymer as the basic raw material, which can prevent liquid leakage and prevent gas volatilization. It is widely used in construction, traffic, subway, tunnel and engineering construction.

The main function of the waterproof plate is to prevent liquid leakage and gas volatilization, the role of the waterproof plate in the rock engineering is mainly for seepage prevention and isolation, but it also plays a role in strengthening and protecting. It is mainly used in: earth and rock dam, rockfill dam, masonry dam, concrete dam, tailings dam, sewage dam, channel, liquid storage tank and other engineering seepage prevention, subway, basement and tunnel seepage prevention lining, highway and railway foundation seepage prevention, sanitary landfill with filament geotextile, bentonite waterproof blanket and other geomaterials use.
