Waterproof sheet

Waterproof sheet

Waterproofing board is a kind of anti-seepage material made from high polymer plastics, which can both prevent liquid leakage and prevent gas volatilization. It is widely used in construction, transportation, subways, tunnels, and engineering projects.

Feature

The primary function of waterproof boards is to prevent liquid leakage and gas volatilization. In rock engineering, their main roles are anti-seepage and isolation, while also serving to reinforce and protect. They are mainly used for: anti-seepage in earthfill dams, rockfill dams, masonry dams, concrete dams, tailings dams, wastewater reservoir dams, canals, liquid storage pools, and others. Additionally, they are applied in waterproof linings for subways, basements, and tunnels, as well as in anti-seepage measures for highway and railway foundations. They are also used in conjunction with geotextiles like long-fiber geotextiles and bentonite waterproof membranes in sanitary landfill sites, etc.
