CompositeGeotextile membraneGeosynthetic composite membrane is an impermeable material made by combining geotextiles with geomembranes. It is primarily used for waterproofing, and the composite membranes come in types with 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. They have high physical and mechanical properties such as tensile strength, tear resistance, and puncture resistance, meeting the needs of civil engineering in water conservancy, municipal, construction, transportation, subway, and tunnel projects. Due to the use of high polymer materials and the addition of anti-aging agents during the production process, they can be used in unconventional temperature environments.
Performance Features:
The product features high strength, good elongation properties, large deformation modulus, resistance to acids and alkalis, corrosion resistance, aging resistance, and excellent moisture-proof performance.
Application:

Composite geomembrane boasts high tensile, tear, and puncture resistance, meeting the civil engineering needs for waterproofing, isolation, reinforcement, and crack-proofing in water conservancy, municipal, construction, transportation, subway, tunnel, and infrastructure projects. Commonly used for waterproofing of embankments and drainage channels, as well as for waste disposal site pollution control.

Leachate prevention for landfill, wastewater, or sludge treatment.

2. River embankments, lake dams, tailings dams, wastewater embankment reservoirs, canals, liquid storage ponds (pits, mines).

3. Subway, basement, and tunnel, tunnel seepage-proof lining.

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

5. Levee/dam horizontal seepage prevention covers, vertical seepage proofing of foundation, construction cofferdam, waste material site.

6. Sea and freshwater aquaculture farms.

7. Highway, expressway, and railway subgrades, waterproofing layers for expansive soils and collapsible loess.

8. Roof Waterproofing.
