Composite geomembrane also belongs to the category of geosynthetic materials. As one of the geosynthetic materials, this

product is made from synthetic plastics, synthetic fibers, and synthetic rubber as the basic raw materials, and is mainly used to

enhance and protect the soil structure, surface, and various types of soil. Composite geotextiles have been widely used in various

engineering fields such as highways, roads, dams, railways, water conservancy projects, large buildings, hydropower plant ash

dam construction, non-ferrous metal tailings treatment, and others.

Geomembrane is a geotextile anti-seepage material made by using plastic film as the anti-seepage raw material and then com-

pounding it with non-woven fabric. Its anti-seepage performance is still mainly based on plastic film. It mainly includes polyvinyl

chloride (PVC) and polyethylene (PE), both of which are high molecular weight chemical materials with the characteristics of light

weight, low specific gravity, strong elongation, strong adaptability to deformation, corrosion resistance, low temperature resistance,

and excellent anti freezing performance.

difference

The raw materials are different. Although both belong to geosynthetic materials, there are differences in the manufacturing process of

raw materials. The geomembrane is made of plastic film as raw material, which is combined with non-woven fabric to form a geotextile

anti-seepage material; Composite geomembranes use synthetic plastics, synthetic fibers, and synthetic rubber as basic materials to pro-

duce various products.

Construction technology. Geomembranes use thermal welding to heat treat the surface of the PE film connection, causing it to completely

melt, and then fuse into one under pressure; The geomembrane in the composite geomembrane is the intermediate layer, ensuring that

the anti-seepage layer is not penetrated by water. In order to reduce the exposure to ultraviolet rays and shorten the service life, it is

advisable to use the buried method for laying.

The performance is different. Geomembranes have high strength, strong elongation and deformation adaptability, and excellent permeability

and physical and mechanical properties of composite geomembranes.
