Tailings Storage Protection with HDPE Textured Geomembrane for Harmful Substance Prevention
Product Introduction
Columnar point rough surface geomembrane is a special type of geomembrane, which increases its friction coefficient and adhesion by adding columnar or point-like texture to the surface of the film.
The spray-coated geotechnical membrane has the following performance characteristics:
Reliable Impermeability: With a low permeability coefficient, it effectively prevents liquid seepage.
Easy Construction and Laying: Convenient for installation and construction.
High Strength: Possesses high tensile strength, elongation at break, and puncture resistance.
Material stability: Strong resistance to chemical agents, suitable for various environments.
High seam strength: The seams are connected by a double-seam hot welding machine, making them less prone to leakage.
The application fields of spray rough geotechnical membrane are very extensive, mainly including:
Landfill : Used to prevent leachate from seeping through.
Tailings Storage Facility: Prevents leakage of harmful substances.
Channel Lining: Used to prevent water seepage.
Dike Seepage Prevention: Protects dikes from water erosion.
Subway Engineering: Used for waterproofing and seepage prevention.
