SEP-3000 Self-adhesive HDPE Waterproofing Membrane

Main features

1) Brand-new adhesive technology: Cement slurry reacts with special macromolecular polymer and bonds with adhesive layer to form a permanent organic integration with no channeling. Even if the membrane is partially damaged, water will be limited within small scope, which improves reliability of the waterproofing layer.

2) Cavity pavement, no influence by settlement deformation.

3) Excellent property of shock resistance and puncturing resistance, endurable to directly engineering load and shock from steel framework. Concrete can be acted directly without extra protection.

4) Strong self-curing ability of synthetic adhesive agent and outer surface elastic coating layer, unique self-curing ability to slight engineering damage;

5) Strong chemical-resistance, strong resistance to alkaline water from concrete, no risk of damages from household waste and organisms, mould proof and corrosion resistance;

Range of application

Suitable for waterproofing and drainage projects such as various underground buildings, cave depots, channels, subways, and municipal construction, etc.
