HDPE Rough Surface Geomembrane Anti Seepage For Reservoir Dam

Special HDPE Rough Geomembrane For Seepage Prevention And Stability Of Reinforced Structure Of Reservoir Dam

Product Introduction
Cylindrical rough surface geomembrane is a kind of geomembrane with special surface texture, which is mainly used to improve the anti-slip performance and adhesion of geomembrane in anti-seepage engineering.

Product Properties
1. Surface texture: The surface of the cylindrical point rough geomembrane has columnar or point-like textures that provide additional friction and prevent the geomembrane from sliding on slopes.
2. High coefficient of friction: The column point design significantly improves the friction coefficient of the geomembrane, helping to maintain stability on slopes or vertical surfaces.
3. Impermeability: It maintains the basic impermeability function of the geomembrane and effectively prevents the penetration of water and pollutants.
4. Chemical corrosion resistance: It has good chemical corrosion resistance and can resist the erosion of various chemical substances.
5. Environmental stress cracking resistance: It is not easy to crack in harsh environments and maintains good stability.
6. Temperature adaptability: It has good heat resistance and cold resistance and is suitable for different climatic conditions.

Product Application
1. Tailings pond: used in the seepage prevention and stabilization project of tailings pond to prevent the leakage of harmful substances.
2. Water conservancy projects: such as reservoirs, DAMS, etc., to enhance the structure of seepage prevention and stability.
3. Slope engineering: Suitable for slopes where stability needs to be enhanced, especially on steep or soft soils.
4. Landfill: slope anti-slip and anti-seepage for landfills to improve the safety of the project.
