Product Introduction: The HDPE non-asphalt based self-adhesive membrane waterproof roll is a specialized waterproof material researched and developed for pre-laid positions in building waterproofing. It is composed of a polymer sheet, polymer self-adhesive membrane, and anti-adhesive layer, serving as a non-asphalt polymer pre-laid waterproof product designed to integrate 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, resulting in effective interlocking bonding and strong intermolecular forces. After concrete curing, the gaps between the polymer pre-laid waterproof roll and the main structure are permanently sealed to the maximum degree, completely eliminating water seepage channels.
