Pre-applied High Density Polyester (HDPE) Self-adhesive Waterproof Membrane
 
1. Introduction:
Pre-applied high density polyester (HDPE) self-adhesive waterproof membrane, which is composed of one thick HDPE backing layer, an aggressive pressure sensitive adhesive and trafficable weather resistant protective granular coating, is specially designed for underground engineering constructions with international advanced technology. And it can bond the later cast concrete form a firm structure, so that prevents water ingress or migration.
 
2. Features:
1). Advanced wet bonding technology: When pouring concrete, the cement mortar and the macromolecule polymer in the adhesive layer of sheet material moisture cure and bind together, the sheet material and structural layer concrete forms a permanent integration, avoiding water ingress or migration.
2). Both the advantages of polymer membrane and self-adhesive membrane, can be applied to wet base surface, weatherproof, can save the duration, reduce project cost.
3). Can receive pedestrian or traffic immediately after application and makes convenient for subsequent placing of reinforcement, site contamination is easy to be removed.
4). Impact and puncture resistance, can withstand heavy duty loading, protect structure from salts and sulphate attack.

3. Specification:

4. Application: Special designed for the underground projects.
1) Waterproofing to basements of industrial and civil engineering.
2) Pre-applied waterproofing system for walls, tunnels and subways.
