Product Category：Geomembrane
A composite geomembrane (also known as a composite impermeable membrane) is a type of impermeable material manufactured using HDPE as the base layer, combined with geotextile. It can be classified into one fabric one membrane and two fabrics one membrane.
Performance
Composite geomembranes exhibit excellent impermeability, high strength, superior elongation resistance, resistance to acids, alkalis, and corrosion, anti-aging properties, high tensile and tear strength, and outstanding puncture resistance.
Application
It is widely used for impermeability purposes in environmental protection and sanitation (landfills, wastewater treatment ponds), water conservancy projects (artificial lakes, canals, reservoirs), municipal construction projects (underground structures, rooftop gardens, warehouses), landscaping, greening projects, petrochemical systems, aquaculture, and salt industry engineering.
