CompositeGeotextile membraneGeosynthetic composite membrane is an impermeable material made by bonding geotextiles with geomembranes. It is primarily used for waterproofing and comes in two types: one geotextile and one geomembrane, or two geotextiles and one geomembrane. The width ranges from 4 to 6 meters, and the weight is between 200 to 1500 grams per square meter. It boasts high mechanical properties such as tensile strength, tear resistance, and puncture resistance, meeting the needs of civil engineering projects including water conservancy, municipal, construction, transportation, subway, and tunnels. Due to the use of high polymer materials and the addition of anti-aging agents in the production process, it can be used in unconventional temperature environments.
Performance Features:
The product features high strength, excellent elongation properties, large deformation modulus, resistance to acids and alkalis, corrosion resistance, aging resistance, and good waterproofing performance.
Application:

Composite geomembrane boasts high physical and mechanical properties such as tensile strength, tear resistance, and puncture resistance, meeting the civil engineering needs for seepage prevention, isolation, reinforcement, and crack reinforcement in water conservancy, municipal, construction, transportation, subway, tunnel, and construction projects. Commonly used for seepage control in embankments and drainage channels, as well as for waste disposal site pollution control.

Landfill, wastewater, or sludge treatment with impermeable lining.

2. River embankments, lake dams, tailings dams, waste water dam reservoirs, canals, liquid storage ponds (pits, mines).

3. Subway, basement, and tunnel waterproofing and lining.

4. Roadbed and other foundation anti-seepage against salinization.

5. Embankment/Levee Seepage Prevention Matting, Foundation Vertical Seepage Barrier, Construction Cofferdam, Waste Material Site.
