HDPE Textured Geomembrane For Enhanced Impermeability And
Environmental Protection
Product Introduction
Cylindrical point rough geomembrane is a type of geosynthetic
material used in civil engineering whose surface is designed with
special column points or textures to increase friction and adhesion
with soil or other materials.
Product Properties
1. Enhanced coefficient of friction: The column point design
provides a higher coefficient of friction, helping to prevent
sliding of geomemes in slope or vertical applications.
2. Good impermeability: It maintains the excellent impermeability
of HDPE geomembrane and effectively prevents the penetration of
water and pollutants.
3. Chemical corrosion resistance: can resist the erosion of a
variety of chemical substances, suitable for use in a variety of
environmental conditions.
4. Resistance to environmental stress cracking: Excellent
resistance to environmental stress cracking, able to maintain
stability 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: 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.
