Waterproof and Durable Compound Geomembrane for Various Applications
Product Introduction
Compound geomembrane is an impermeable material made by combining geotechnical fabrics with geomembranes. It uses plastic film as the base material for seepage prevention and is combined with non-woven fabric to form a geotechnical anti-seepage material.
Product Properties
Good physical and mechanical properties: Under harsh working conditions (such as being submerged in water or laid on soil with high humidity), it exhibits excellent resistance to hydrolysis and good mechanical properties in wet conditions.
Withstand environmental factors
Resistant to ultraviolet radiation, hydrolysis, and high and low temperatures: Exposed to sunlight, so it needs to have resistance to ultraviolet rays, and it needs to adapt to the temperature when in contact with materials such as asphalt, requiring a high melting point.
Chemical resistance, corrosion resistance, and anti-mildew: Due to different types of water and soil (pH, salinity, elements contained, etc.) that it comes into contact with, it must have chemical stability.
Good water permeability: Good water permeability is required for filtration and drainage.
Product Application
It is mainly used for reinforcing railway subgrade, maintaining highway pavement, protecting gymnasiums, dams, isolation of hydraulic engineering buildings, tunnels, coastal beach mudflats, reclamation, environmental protection and other projects. It is also used for impervious purposes in water conservancy, chemical industry, construction, transportation, subway, tunnel, garbage disposal site and other projects.
