Reservoir Seepage Control Use Composite Geomembrane
Composite Geomembrane (Geotextile-Geomembrane Composite) is created by heat-bonding a nonwoven geotextile layer to a geomembrane. This composite combines the benefits and features of both materials. The geotextile enhances the system by offering better puncture resistance, tear propagation control, and improved frictional properties, which help reduce sliding. Additionally, the geotextile itself contributes tensile strength to the overall structure.
Composite Geomembrane Specifcations
The composite geomembrane liner has the advantages of geomembrane and geotextile at the same time. Geomembranes provide excellent seepage, leak, moisture, tear, and puncture resistance. The geotextile layer increases the tensile strength, and the composite geomembrane lining plays a great role in the landfill.
On the basis of HDPE geomembrane, the composite geomembrane liner has both flexibility and ductility to improve the waterproof and seepage resistance.
The composite geomembrane is thermally bonded by non-woven or woven geotextile and HDPE geomembrane through calendering technology. Composite geomembrane and geomembrane have the advantages of geomembrane and geotextile at the same time. It not only maintains the waterproof, anti-seepage, and tear resistance of the geomembrane while maintaining the characteristics of the geotextile but also protects the geomembrane.
