Product Description
Pe Pp Waterproof Membrane For Tunnel Culvert And Underground Utility Tunnel
Product Advantages for Basement Waterproofing
Strong adaptability to damp substrate: It can be constructed directly in damp and humid basement environments. Only no standing water on the substrate is required without full drying, greatly reducing construction difficulty and shortening the construction period.
Firm cement wet bonding, anti-channeling water: The double-sided polypropylene mesh fiber structure of the membrane penetrates and occludes with cement adhesive to form a seamless waterproof system, effectively solving common problems of layer separation and lateral water channeling in basements.
Excellent corrosion resistance and durability for underground environment: The virgin polyethylene core is alkali-resistant, water-corrosion-resistant and mildew-proof. It is not eroded by moisture, salt and alkali in long-term buried conditions, ensuring stable service life of concealed underground projects.
Superior mechanical performance and deformation resistance: High tensile strength and elongation enable the membrane to adapt to subtle settlement and cracking of basement substrate, with excellent crack-resistant and puncture-resistant performance for complex underground working conditions.
Safe and eco-friendly cold construction: Full wet-lay construction with cement, no open flame, no solvent and no toxic volatiles. It ensures safe and pollution-free construction in enclosed and poorly ventilated basement spaces.
Strong process compatibility and convenient follow-up construction: After the waterproof layer is formed, protective layer pouring, steel bar binding and plastering can be carried out directly without additional interface treatment, simplifying follow-up processes and reducing engineering costs.
Cost-effective for large-scale underground projects: It features low material cost, high construction efficiency and easy maintenance, suitable for large-area waterproofing and anti-seepage projects such as basement floors, side walls, civil air defense projects and tunnels.
