Product Description
High Strength Pe Pp Composite Waterproof Membrane For Roof Engineering Projects
Product Description
Polyethylene polypropylene waterproof membrane is a multi-layer polymer waterproof material composited and formed with polyethylene and polypropylene fiber as main raw materials and various additives added. The product boasts good tensile strength, impermeability and weather resistance. Easy to construct, it is widely used in building waterproof projects such as bathrooms, roofs, basements and reservoirs.

Core Product Features
- Stable and durable material with excellent anti‑aging performance Made of pure polymer resin, free of asphalt and other aging‑prone organic components. Formulated with special anti‑aging and anti‑oxidation additives. It will not degrade, powder or crack when buried underground. It delivers outstanding resistance to soil acid‑alkali, groundwater corrosion and moisture erosion. Its service life is far longer than conventional waterproof membranes, providing long‑term waterproof protection for buildings.
- Dense structure with high impermeability and strong water‑blocking capacity The intermediate polyethylene waterproof core layer features a dense pore‑free structure with remarkable water impermeability. Integrally formed without hidden splicing risks, it effectively blocks water penetration and withstands water pressure impact, fundamentally eliminating water seepage and moisture return for long‑lasting anti‑seepage stability.
- High toughness and deformation resistance, crack‑proof and puncture‑resistant The membrane boasts high tensile strength and superior elongation at break with great toughness. It adapts to slight settlement and telescopic deformation of the base layer, avoiding waterproof damage caused by minor base cracks. It also has good puncture‑resistance and wear‑resistance to resist external damage from construction and foundation movement, ensuring stable waterproof structure.
- Safe and convenient construction for multiple scenarios Adopt cold wet‑laying construction process. No open‑fire heating or base‑drying is required, completely eliminating safety hazards from hot‑melt construction. Suitable for humid, enclosed and poorly‑ventilated working environments. Low requirements for base flatness and dryness. Simple and efficient installation with high fault tolerance, greatly reducing construction difficulty and rework costs.
- Firm integrated bonding to prevent water channeling and hollowing The rough‑fibered polypropylene non‑woven fabric surface can closely interlock and bond with cement slurry and cement mortar. After installation, it integrates with the building structural layer and protective layer without hollowing, delamination or edge curling. It thoroughly solves common defects of traditional membranes such as delamination, water channeling and hidden leakage.
- Eco‑friendly and safe for various engineering projects Formaldehyde‑free, odorless, non‑toxic and harmless. No pollutants are released during construction and service, and it will not contaminate soil or groundwater. Compliant with green building standards, it is widely used for waterproofing in residential buildings, commercial buildings, civil air‑defense projects, municipal infrastructure and other scenarios.
