Composite Geomembrane ( Composite Geomembrane One Geotextile) is made by heat-bonding a nonwoven geotextile to a geomembrane sheet. The composite has functions and advantages of both the geotextile and geomembrane.

The geotextiles provide increased resistance to puncture, tear propagation, and friction related to sliding, as well as providing tensile strength in and of themselves.

The geomembrane provides waterproofing and reinforcement functions.
