Material: Composite geomembrane is usually composed of synthetic materials such as polyethylene, polypropylene, polyester, polyvinyl chloride, etc., and is made through composite technology.

Structure: Composite geomembrane has a multi-layer structure, and each layer of material has different functions, such as anti-seepage, tensile, anti-corrosion, etc.

Function: Composite geomembrane has various functions, such as anti-seepage, isolation, tensile strength, chemical corrosion resistance, etc. It can play a role in water conservancy engineering, environmental engineering, municipal engineering, and other fields.

Application: Composite geomembranes are widely used in engineering projects such as reservoirs, dams, landfills, chemical ponds, and road foundations, for purposes such as anti-seepage, isolation protection, and soil stability.

Advantages: Composite geomembrane has excellent anti-seepage performance, tensile performance, and chemical corrosion resistance, which can protect land resources, maintain the water and soil environment, and improve the stability of engineering structures.
