composite geomembrane:
Compound geomembrane is compounded with geotextiles and geomembrane impermeable material, it is mainly used for seepage control, composite geomembrane is divided into a cloth a film, a film and two cloth wide 4 to 6 m, weight of 200-1500 - g/m2, tensile and tearing resistance, bursting physical mechanics performance index is high, can satisfy the water conservancy, municipal, construction, transportation, subway, tunnel and other civil engineering needs. Due to the choice of the polymer material and production process to add the aging proof agent, it can be used in the abnormal temperature conditions.
