Waterproof Board for seepage control

EVA waterproof board is a polymer waterproofing material manufactured through a flat extrusion process using ethylene-vinyl acetate (EVA) copolymer as the primary raw material. It is designed for waterproofing and seepage control in railway tunnels, subway tunnels, highway tunnels, and other underground structures.   EVA waterproof board offers good flexibility, elasticity, and low-temperature bending performance. These properties make it suitable for installation along different tunnel profiles, including crowns, shoulders, and sidewalls. Depending on the engineering design, it can be integrated with geotextiles, drainage pipes, and other waterproofing components to form a complete tunnel waterproofing system.
