Waterproof boards primarily refer to geosynthetic materials with a thickness of 1.0mm or more, mainly used for anti-seepage, reinforcement, resistance to acids and alkalis, and high corrosion resistance. They are widely applied in industrial, agricultural, hydraulic, and fishing sectors. They are a key material for energy conservation.
The primary component of both geomembrane and waterproofing boards is polyethylene, and their functions are largely similar. The difference lies in the thickness, with geomembrane thicknesses around 0.5mm and waterproofing boards being thicker.
