Easy Construction Laying Roughened Geomembrane For Environmental Projects
Product Introduction
Rough Geomembrane is a special treated geomembrane with a particle-like rough surface formed through a special process, which enhances the friction performance of the membrane surface. This membrane utilizes updated production equipment during its production, resulting in a rough texture on the surface of the polyethylene impervious membrane, hence it is called spray rough geomembrane. It is mainly used for projects requiring larger friction coefficients, such as slope membrane surface coverage projects, including landfills, tailings storage yards, channel seepage prevention, dam seepage prevention, and subway engineering, etc.
Product Properties
♦ Reliable Impermeability
♦ Easy Construction Laying
♦ High Strength and Elongation
♦ Material stability and strong resistance to chemical agents
♦ Secure Seam Treatment
Product Application
► Hydraulic Engineering: Can be used for water seepage prevention in reservoirs, artificial lakes, fish farms, etc.
► Environmental Engineering: Suitable for landfills, waste liquid storage, and liquid storage facilities.
► Municipal Engineering: Used for canal seepage prevention, dam seepage prevention, etc.
► Traffic Engineering: Used in highway, railway, tunnel, etc. engineering projects.
► Construction Industry: As a moisture-proof material for basement floors and underground warehouses in buildings.
