EVA waterproof boards are made from high polymer materials, serving as a moisture-proof material that can prevent both liquid leakage and gas volatilization. They are extensively used in construction, transportation, subway, tunnel, and engineering projects.

EVA waterproof sheet, also known as geotextile membrane. It's customary to refer to geotextile membranes with a thickness of ≥0.8mm as waterproof sheets, while those with a thickness of <0.8mm are called geotextile membranes. They are a type of waterproofing material made from high polymer resins, and are categorized into homogeneous waterproof sheets and composite waterproof sheets.

EVA waterproof boards primarily prevent liquid leakage and gas evaporation. In rock engineering, their main role is to prevent seepage and isolate, while also providing reinforcement and protection. They are mainly used for: seepage prevention in earth and rock dams, stone-filled dams, masonry dams, concrete dams, tailings dams, wastewater reservoir embankments, canals, liquid storage pools, and more. They are also used for waterproof lining in subway, basements, and tunnels, seepage prevention in highway and railway foundations, and in conjunction with geotextiles like long-fiber geotextiles and bentonite waterproof membranes in sanitary landfill sites, among other applications.
