Composite Geomembrane Introduction (One geomembrane and two geotextiles)

Composite geomembrane is manufactured by thermally bonding one PE geomembrane between two layers of filament or short-fiber nonwoven geotextiles. It combines reliable planar drainage performance and excellent impermeability.

The attached geotextile layers improve puncture resistance, tear resistance, interface friction and tensile strength.

The middle geomembrane layer provides waterproofing and anti-seepage functions.

Its physical and hydraulic properties meet or exceed Chinese national standard GB/T17642.

Features and Benefits

• Excellent waterproof & anti-seepage performance

• High puncture resistance

• Large friction coefficient

• Good aging resistance

• Wide temperature adaptability

• Cost-effective and simple installation
