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
It is manufactured through a filament spunbond nonwoven process and has the following salient features:
High strength: The structure of the filament gives it excellent tensile strength and can withstand large external forces and loads. For example, in large-scale filling projects, it can effectively prevent the tensile deformation and rupture of soil.
Good uniformity: The production process ensures uniform performance of the material in all directions, ensuring stability and reliability in engineering applications.
Excellent corrosion resistance: It can maintain stable performance for a long time under various harsh environmental conditions and is not corroded by chemicals such as acids and alkalis. Excellent performance in land remediation projects in some chemically contaminated areas.
Filament spunbond nonwoven geotextiles have a wide range of applications:
road works
It is used to strengthen the base layer, improve the load-bearing capacity of the road, and reduce uneven settlement of the road surface.
Acts as an isolation layer to prevent mutual interference between different material layers.
Water Conservancy Project
Used for anti-seepage treatment of reservoirs and channels, effectively reducing leakage losses of water resources.
As a slope protection material, it enhances the erosion resistance of river banks and embankments.
In the field of environmental protection:
Used to cover and isolate landfills to prevent the spread of harmful substances.
