Product Introduction: 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.
Product Description: 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.
