Composite geomembrane is an impermeable material made by bonding geotextiles with geomembranes. It is primarily used for seepage prevention and comes in two types: one geotextile and one geomembrane, or two geotextiles and one geomembrane, with widths ranging from 4 to 6 meters and weights from 200 to 1500 grams per square meter. It boasts high physical and mechanical properties such as tensile strength, tear resistance, and puncture resistance, meeting the needs of civil engineering projects like water conservancy, municipal, construction, transportation, subway, and tunnel. 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. One geotextile and one geomembrane (geotextile: 100-1000 g/m², geomembrane thickness: 0.1-1.5 mm)

Two fabrics and one film (fabric: 80-600g/m², film thickness: 0.2-1.5mm)
One fabric and two films (fabric: 100-1000g/m², film thickness: 0.1-0.8mm)
Doubao Double Film (Fabric: 100-1000g/m², Film Thickness: 0.1-0.8mm)
