Product Introduction: Developed as a specialized waterproof material for pre-laid construction waterproofing positions, the HDPE non-asphalt based self-adhesive membrane waterproof roll is composed of a polymer sheet, polymer self-adhesive membrane, and anti-adhesive layer. It is a non-asphalt polymer pre-laid waterproof product tailored to achieve integral fusion with concrete structures.
Product Description: Under pressure, the polymer self-adhesive membrane and the unset cement paste in concrete undergo creep and mutually penetrate the anti-adhesive layer, forming robust interlocking adhesion and substantial intermolecular forces. After concrete curing, the gaps between the polymer pre-laid waterproof roll and the main structure are permanently sealed to the maximum extent, thoroughly eliminating water channeling paths.
