Pre applied self adhesive HDPE  waterproof membrane with sand for tunnel is specially used in underground project, it can bond with concrete layer tightly. After Membrane bonding with concrete, water can be blocked between membrane and concrete, which can improve the reliability.

Where to use

Basement

Subway

Tunnel

Cave

Other underground public constructions.

Advantages

1.Good bonding with concrete applied on membrane, to block water between membrane and concrete further to protect concrete effectively.

2.Low flatness requirement to substrate, reliable overlapping; mechanical fixing, easy application.

3.Sound anti-puncture performance.

4.Adaptable to settlement and distortion.

5.Weather-resisting and anti-UV.

6.Resist to acid, alkali, mold.

7.Eco-friendly material
