Product Introduction
Composite geomembrane(also named as waterproofing geotextile) is a kind of non-woven geotextile compound geomembrane taking non-woven geotextile as base material, and HDPE geomembrane as the membrane material. Classified by base material, it can be divided into short-fiber non-woven composite geomembrane and filament non-woven composite geomembrane; Classified by structure, it can be divided into one geotextile and one geomembrane, two geotextile and one geomembrane.
Product Application
1. It is applied in horizontal impervious blanket and vertical anti-seepage layer of foundation in front of dams such as soil dam, rock-fill dam, stone dam, and compressed concrete dam;
2. Construction cofferdam of tailing dam, sewage dam and reservoir area;
3. Channel, liquid pool, waste storage;
4. Anti-seepage lining of subway, basement and tunnel, cave;
5. Treatment of salt marsh of foundations of road, expressway and railway and other roadbed;
6. Waterproof layer of swelling soil and collapsible loess; Roof waterproof.
