Composite geomembrane is composed of nonwovens or woven fabrics and polyethylene geomembrane. The nonwovens or woven fabrics can protect the geomembrane from mechanical damage and increase the friction coefficient with the base surface, which is conducive to improving the engineering quality and reducing the cost. The width of the product is 1-6m.
