Enhanced Friction HDPE Textured Geomembrane For Slope And Landfill
Applications
Product Introduction
Columnar point rough surface geomembrane is a special
type of geomembrane, which increases its friction coefficient and
adhesion by adding columnar or point-like texture to the surface of
the film.
Product Properties
1. Enhanced coefficient of friction: The column point design
provides a higher coefficient of friction, helping to maintain
stability on slopes or vertical surfaces.
2. Good impermeability: it maintains the basic function of the
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 a variety of
environments.
4. Environmental stress cracking resistance: It is not easy to
crack in harsh environments and maintains good stability.
5. Temperature adaptability: It has good heat resistance and cold
resistance and is suitable for different climatic conditions.
Product Application
1. Slope engineering: Used for anti-slip and anti-seepage of
slopes, especially on steep slopes.
2. Landfill: Used on the slopes of landfills to prevent the
infiltration of pollutants and landslides.
3. Tailings pond: used for seepage prevention and stabilization of
tailings ponds to prevent 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.
