Composite Geomembrane

Composite Geomembrane

Composite geomembrane is a multi-layer geosynthetic material combining geotextile and HDPE geomembrane through advanced calendering and hot-melt processes. Engineered for superior anti-seepage performance, it offers high tensile strength, puncture resistance, and chemical durability. Available in configurations of one or two geotextiles with one or multiple geomembranes, it is widely applied in landfills, water conservancy projects, tunnel lining, and environmental containment systems.
