Multi-Purpose Roughened Geomembrane For Landfill And Tailings Storage
Product Introduction
Cylindrical point rough geomembrane is a special type of geomembrane whose surface has a cylindrical or point-like rough texture, which is designed to increase the friction and adhesion between the geomembrane and soil or other materials.
Product Properties
1. Impermeability: Like ordinary geomembrane, column point rough geomembrane has excellent impermeability and can effectively prevent the penetration of water and pollutants.
2. Chemical corrosion resistance: can resist the erosion of a variety of chemical substances, suitable for use in a variety of environments.
3. Resistance to environmental stress cracking: It can remain stable in harsh environments and is not easy to crack.
Product Application
1. Landfill: Used as an impermeable layer to prevent contaminants from seeping into groundwater.
2. Tailings storage yard: prevent harmful substances in tailings from penetrating into the environment.
3. Slope engineering: Due to its high friction, it is particularly suitable for slope engineering to prevent geomembrane from sliding.
4. Dam anti-seepage: enhance the anti-seepage capacity of the dam to prevent water penetration.
5. Artificial lakes and reservoirs: as impermeable layers, maintain the stability of water bodies.
