Enhance Your Project with Compound Geomembrane Perfect for Water Conservancy Environmental Protection and Transportation
Product Introduction
Composite geomembrane is a multi-functional impervious material that combines the advantages of geotechnical fabric and geomembrane. It is widely used in various fields such as water conservancy projects, environmental protection, and transportation construction. Here is a detailed introduction to composite geomembranes.
Product Properties
Composite geomembranes possess a variety of excellent properties, including good thermal resistance, cold resistance, and chemical stability, high tensile strength, anti-aging and corrosion resistance. They also have excellent dielectric properties, resistance to environmental stress cracking, and increased friction coefficients between the membrane and the base layer due to non-woven fabric, providing good skid resistance. In addition, composite geomembranes can withstand plant root penetration, maintain waterproof function for a long time, and form a high-strength waterproof layer with strong resistance to backwater pressure. They are resistant to perforation, bursting, tearing, and fatigue.
Product Application
Composite geomembrane is widely used in many fields, such as
hydraulic engineering reinforcement of reservoirs, lakes and
canals, because of its excellent impermeability, tensile strength
and other mechanical properties.
♦ Municipal construction: includes impervious lining for subways,
basements and tunnels.
♦ Environmental Protection: anti-seepage treatment of landfill.
♦ Agricultural Water Conservancy: anti-seepage pavement of
irrigation system.
♦ Traffic facilities: highway, railway subgrade anti-seepage
treatment.
