High And Low Temperature Resistant Corrosion And Seepage Resistant
HDPE Column Point Rough Surface Geomembrane
Product Introduction
Cylindrical point rough surface geomembrane is a kind
of geomembrane with special surface treatment, and its surface is
designed with columnar or point-like texture to improve the
coefficient of friction and adhesion with soil or other materials.
Product Properties
1. Enhanced coefficient of friction: The column point design
significantly improves the friction coefficient of the geomembrane,
helping to maintain stability on slopes or vertical surfaces.
2. Good impermeability: the column point rough geomembrane inherits
the excellent impermeability characteristics of HDPE geomembrane,
effectively preventing the penetration of water and pollutants.
3. Chemical resistance: can resist the erosion of a variety of
chemical substances, suitable for use in a variety of environmental
conditions.
4. Environmental stress cracking resistance: Excellent
environmental stress cracking resistance, not easy to crack in
harsh environments.
5. Temperature adaptability: It has good heat resistance and cold
resistance and can be used in a wide temperature range.
Product Application
1. Slope engineering: Especially suitable for slope seepage
prevention projects that need to enhance stability.
2. Landfill: It is used in slope anti-slip and anti-seepage of
landfill to improve the safety and environmental protection of the
project.
3. Tailings pond: used for seepage prevention and stabilization of
tailings pond to prevent the leakage of harmful substances.
4. Water conservancy project: Used in reservoirs, DAMS and other
water conservancy projects to enhance the anti-seepage capacity of
the structure.
