Geocomposite drainage membrane is made by non woven geotextile and PE/PVC geomembrane Categories are including geotextile and geomembrane, geomembrane with non woven geotextile on both sides, non woven geotextile with geomembrane on both sides, multi-layer geotextile and geomembrane.

Composite Geomembrane is HDPE geomembrane heat bonded nonwoven geotextile on one side or both sides by calendaring processing technology, The composite geomembrane can provide the advantages of both geotextiles and geomembranes. It remains the mechanical properties of base geotextile, meanwhile improves the impermeability.
