Advanced HDPE Textured Geomembrane For Slope Anti-Slip And
Anti-Seepage Solutions
Product Introduction
Cylindrical point rough geomembrane is a high performance
geosynthetic material that provides additional friction and
adhesion by forming special column points or textures on the
surface of the geomembrane.
Product Properties
1. High coefficient of friction: The column point design
significantly improves the coefficient of friction between the
geomemofilm and soil or other materials, helping to prevent sliding
in slope or vertical applications.
2. Enhanced adhesion: The column point structure enhances the
adhesion of the geomembrane and is suitable for applications where
additional stability is required.
3. Excellent impermeability: Inherited the core advantages of
high-density polyethylene (HDPE) geomemofilm, effectively
preventing the penetration of water and pollutants.
4. Chemical resistance: It has good resistance to most chemical
substances and is suitable for use in a variety of environmental
conditions.
5. Resistance to environmental stress cracking: Excellent
resistance to environmental stress cracking, able to maintain
stability in harsh environments.
6. Temperature adaptability: It has good heat resistance and cold
resistance and can be used in a wide temperature range.
Product Application
1. Slope engineering: Suitable for slope anti-seepage engineering
where stability is required, especially in steep or unstable
terrain.
2. Landfill: used for slope anti-slip and anti-seepage of landfill
to improve the safety and environmental protection of the project.
3. Tailings pond: used in the seepage prevention and stabilization
project of tailings pond to prevent the leakage of harmful
substances.
4. DAMS and reservoirs: Used for seepage prevention and
reinforcement of DAMS and reservoirs to improve the durability of
the structure.
