Product Description:
Self-adhesive EVA waterproof board is composed of ethylene-vinyl acetate copolymer (EVA) as the main material, self-adhesive glue, surface anti-stick (or reduced stickiness) protective layer (except for the areas where the rolls are lapped), and isolation materials (when necessary). It bonds with the subsequently poured concrete, is applied using the pre-lay method, and the lap edges are joined using hot air welding. No additional layers are needed, and it can also serve as a waterproofing membrane without a protective layer.

Product Features
1、Optimal VA content for balanced high and low-temperature performance.
2、Free of plasticizers and recycled materials, ensuring excellent product performance.
3、Superior physical and mechanical properties, high strength, tear resistance, high elongation, and good resistance to stress cracking.
4、Resistant to acids, alkalis, salts, and other media in concrete or soil, and resistant to mold.
5、High adaptability to construction environments, good heat resistance, and low-temperature flexibility.
6、Soft texture that forms a permanent bond with the concrete structure, enhancing the reliability of the waterproof layer.
7、Good workability, strong weldability, with lap joints welded using hot-melt welding. The welding parameters are adjustable, making construction simple, fast, and the waterproof layer reliably sealed.
Product Application:
It is used for waterproofing projects in tunnels of railways and expressways; waterproofing of culverts for roads and railways; and waterproofing, seepage prevention, and moisture-proof projects for various municipal engineering projects, sewage treatment pools, and civil air defense projects, among other underground construction projects.
