Composite Geomembrane
Composite geomembrane is made of geotextile (base fabric can be filament or short fiber needle punched geotextile ,woven geotextile )and high polymer by calendering and hot-melt technology .It remains the mechanical properties of base fabric and uniformity of film which improve the impermeability .Embossed processing on the film strengthen its friction coefficient,stability and easy for installation .
