Product Introduction:

　　Anti seepage geotextile, also known as composite geotextile film, is a geotextile material composed of a layer of geotextile (long and short needle punched geotextile, woven geotextile, plastic woven fabric, bentonite waterproof blanket, etc.) and a layer of polymer materials (HDPE film, LDPE film, EVA film, etc.) that are pressed and melted together.

　　Performance characteristics:

　　Composite geomembrane is a combination of anti-seepage and drainage, with high strength, high friction coefficient, puncture resistance, aging resistance, acid and alkali resistance, and the prevention of soil erosion.

　　Using geotextile instead of granular material as the protective layer of the geomembrane to protect the impermeable layer of the geomembrane from damage, reduce the grading requirements of the cushion particle size, and have a drainage effect. The friction coefficient is large, which can prevent the sliding of the covering layer. Compared to pure HDPE film and non-woven fabric in composite geomembrane, the friction coefficient is higher. Composite geomembrane can increase the slope ratio and reduce the floor area.

　　Tears, punctures, punctures, and other mechanical strengths are relatively high. It has a certain insulation effect and reduces the damage of soil frost heave to the geomembrane, thereby reducing soil deformation. Buried laying is adopted, which has excellent anti-aging performance and reduces the maintenance of the project. The laying construction is simple, reduces transportation volume, reduces engineering costs, and shortens the construction period.

　　Purpose:

　　Widely used in tailings ponds, liquid storage tanks, water embankments, transportation tunnels, freshwater aquaculture, road construction, airports, drainage, housing, environmental protection and many other fields, it mainly plays a role in anti-seepage, protection, reinforcement and other aspects of engineering.

　　For example:

　　1. Jiangti, Huba and reservoir areas, diversion channels, and storage tanks (pits, mines).

　　2. Subway, basement and tunnel, tunnel anti-seepage lining.

　　3. Salt and anti-seepage measures for roadbed and other foundations.

　　4. Embankment, horizontal anti-seepage cover in front of the dam, vertical anti-seepage layer of the foundation, construction cofferdam, and good material yard.

　　5. Seawater. Freshwater aquaculture farms.

　　6. Waterproof layer for roadbed, expansive soil, and collapsible loess of highways, highways, and railways.
