Product Description
Seepage Prevention And Isolation Composite Geomembrane
Product Introduction：
Composite geomembrane is an impervious material composed of geotextile and geomembrane, which is mainly used for impermeability and isolation. According to the structural form, it can be divided into one cloth and one membrane, two cloth and one membrane, three cloth and two membrane, etc., with high physical and mechanical performance indicators such as tensile resistance, tear resistance and puncture resistance, which can meet the needs of water conservancy, municipal, construction, transportation, subway, tunnel and other projects. Due to the selection of polymer materials and the addition of anti-aging agents in the production process, it can be used in unconventional temperature environments. It is a geosynthetic material composed of a layer of geotextile and a layer of high molecular material (generally membrane material) by geotextile and hot melting composite.
Performance Characteristics:
Tensile resistance, tear resistance, top breaking and other physical indicators are high, the product has high strength, good extension performance, large deformation modulus, acid and alkali resistance, corrosion resistance, aging resistance, membrane fabric composite structure form makes it not only has the impermeability of geomembrane, isolation, but also has the reinforcement, protection, drainage and filtration effect of geotextile.
Function And Use:
1.Roadbed, roof seepage prevention.
2.River dike, lake dam, tailings dam, sewage dam, reservoir area, channel, liquid storage pond (pit, mine).
3.The foundation of roads, highways, railways.
4.Embankment, dam horizontal anti-seepage blanket, foundation vertical anti-seepage layer, construction cofferdam, waste yard.
5.Seawater and freshwater farms.
6.Landfill, sewage or waste treatment seepage.
7.Subway, basement and tunnel, tunnel anti-seepage lining.
