High Strength HDPE Textured Geomembrane For Slope Engineering And
Dam Anti-Seepage
Product Introduction
1. High Density polyethylene (HDPE) : Cylindrical point rough
geomembranes are usually made of high density polyethylene, which
has good chemical resistance and mechanical strength.
2. Columnar point design: The surface has a columnar or point-like
texture that increases friction with 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.
4. Tensile strength: It has high tensile strength and elongation,
and can withstand certain water pressure and adapt to foundation
deformation.
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.
