High Strength Compound Geomembrane For Environmental Protection Systems
Product Introduction
Composite geomembrane is a geosynthetic product made by combining geomembrane and geotechnical fabric through co-pressing or polymer bonding. It comes in various forms such as one fabric and one membrane, two fabrics and one membrane, and two membranes and one fabric. Generally, it has a width of 4m to 6m and a mass of 200 to 1500 grams per square meter. It exhibits high tensile resistance, tear resistance, and puncture resistance, among other physical and mechanical performance indicators.
