Impermeable geomembrane is a special material mainly used in waterproofing and anti-seepage engineering, it is a film-like product made of polymers such as polyethylene (PE), etc. Among them, HDPE (high-density polyethylene) impermeable membrane has been widely used in various impermeable projects because of its excellent performance.

Features of impermeable geomembranes include:
1.Excellent anti-seepage performance: It has a very low water vapor permeability coefficient, which can effectively prevent the passage of liquids and gases, and prevent groundwater, industrial sewage, landfill leachate, etc. from polluting the environment.
2.High strength and ductility: It has good tensile strength and elongation at break, adapts to foundation deformation and settlement, is not easy to break, and can maintain a stable anti-seepage effect for a long time.
3.Chemical resistance: It has high resistance to acids and alkali salts, and can maintain stable performance in various harsh environments.
4.Environmentally friendly and durable: long service life, and can be used, in line with the requirements of sustainable development.
5.Convenient construction: light weight, easy to transport, lay and weld, can adapt to different terrain and complex construction conditions.
Anti-seepage geomembranes are widely used in water conservancy and hydropower projects in reservoir dams and channels seepage prevention, solid waste landfill anti-seepage liner systems, artificial lakes, landscape ponds, golf courses, tunnel engineering, underground building foundation seepage prevention and agricultural irrigation system water source protection and other fields.
