Composite Geomembrane Construction

Composite geomembrane is made by heat-bonding nonwoven or woven geotextile to on one or both sides of HDPE geomembrane by calendaring processing technology. According to the actual application, the composite geomembrane is specifically divided into two types, one geomembrane and one geotextile, one geomembrane and two geotextiles. Composite geomembrane liner provides the advantages of both geotextiles and geomembranes. The geotextile layer increases essential tensile strength and the geomembranes provides excellent impermeable, leak, moisture proof and tear and puncture resistance. Composite geomembrane uses a polymer material and an anti-aging agent is added to the production process, so it can be used in an unconventional temperature environment.

The composite geomembrane has a width of 2-8m and a weight of 200-1500g/m2. It has high physical and mechanical properties such as tensile strength, tear resistance and bursting. The product has high strength, good elongation performance, large deformation modulus and acid resistance, anti-corrosion, anti-aging, good anti-seepage performance that can meet the engineering requirements of water conservancy, municipal administration, construction, transportation, subway, tunnel, widely used in water conservancy dams, traffic tunnels, road construction, airports, drainage, houses, environmental protection, etc., it also commonly used for anti-seepage treatment of dams, drainage ditches, and anti-fouling treatment of waste yards.
