Geomembrane is a polymer-based waterproof barrier material, mainly classified into low-density polyethylene (LDPE) geomembrane, high-density polyethylene (HDPE) geomembrane, and EVA geomembrane. It possesses excellent resistance to environmental stress cracking and chemical corrosion, a wide operating temperature range, and a long service life. It is widely used in landfills, tailings ponds, canals, seepage prevention, dam seepage prevention, and subway projects.

Product Description
Composite geogrids are usually made by combining geogrids with other geotechnical materials such as geotextiles, geomembranes, etc.
The main characteristics of composite geogrid are:
Superior comprehensive performance: Combining the advantages of multiple materials, it has good tensile strength, anti-seepage performance, filtration performance, etc.
Strong synergy: Different materials work together to more effectively utilize their respective functions.
Convenient construction: reduces construction procedures and improves project efficiency.
It has a wide range of applications:
Water conservancy engineering: used for reinforcing, anti-seepage, and slope protection of dams.
Road engineering: Improve roadbed performance and prevent pavement reflection cracks.
Environmental engineering: plays a role in isolation, reinforcement, and anti-seepage in projects such as landfills and sewage treatment plants.
