Composite geomembranes are geosynthetics made up of two or more materials, such as geotextile (or glass fiber net), polymer material and so on, such as PE film and EVA. It is made of geotextile as water conducting layer, polymer material as impervious layer, calendering and hot melt coating. It has unique functions of seepage prevention, protection, reinforcement, drainage and isolation. Its high toughness and excellent chemical resistance and aging resistance are beyond the use index of simple application of cloth or membrane, which is convenient for construction, without adhesives, and has wider application fields and more convenient use.
