Specifically developed for pre-laid building waterproofing applications, the HDPE non-asphalt based self-adhesive membrane waterproof roll consists of a polymer sheet, polymer self-adhesive membrane, and anti-adhesive layer. It is a non-asphalt polymer pre-laid waterproof material engineered to integrate seamlessly with concrete structures.

Under pressure, the polymer self-adhesive membrane and the unset cement paste in concrete creep and mutually penetrate the anti-adhesive layer, forming effective interlocking adhesion and strong intermolecular forces. After concrete curing, gaps between the polymer pre-laid waterproof roll and the main structure are permanently sealed to the maximum extent, completely eliminating water channeling paths.

• Waterproofing for basements, subways, tunnels and other locations
• Projects with high waterproofing requirements
• Green roof systems
• Leakage prevention of underground gas, biogas and other gases

• Pre-laid bonding
• Reliable adhesion and easy maintenance
• Low requirement for base surface, saving construction period
• Optimal cost-performance ratio
