EVA waterproof board with EVA resin as the main raw material, adding certain filler, plasticizer, anti-aging agent, ultraviolet absorbent and other auxiliary materials, kneading, extrusion and other processes made of waterproof and impermeable materials. The tensile strength at break is greater than 16MPa, the elongation at break is greater than 550%, and the tearing strength is greater than 60kN/m. Generally used in new railway, highway, municipal road, light rail transportation construction (including bridge deck, tunnel), roof, underground engineering waterproof, water conservancy construction, sewage treatment engineering, landfill engineering, chemical acid and alkali treatment tank and other environmental protection engineering impermeable and corrosion resistant liner use.

1. The construction process is simple, good operability, strong repairability, no open fire, smokeless, no toxic gas in the construction process, low requirements for the construction environment, especially suitable for tunnels, pipelines and other narrow space and poor ventilation conditions and permeable water environment construction.

2. The connection is welded by special double seam thermal welding machine, with good weld connection effect and high strength. The welding quality can be identified by naked eye, and the waterproof effect is good.

3. The durability of the material is good. The waterproof grade and durability life can be adjusted according to the thickness of the plate.

4. Waterproof system adopts multi-channel waterproof measures, special grouting strengthening measures for weak parts such as construction joints, which can effectively ensure the waterproof effect of construction joints.
