Composite geomembrane (two fabrics and one membrane)

Product Introduction:

Two fabrics and one film is a geosynthetic material composed of two layers of geotextiles (long and short silk needle punched geotextiles, woven geotextiles,

plastic woven fabrics, bentonite waterproof blankets, etc.) and one layer of polymer materials (HDPE film, LDPE film, EVA film, etc.) that are rolled and hot-melt

composite.

Performance characteristics:

Two fabrics and one film have a certain amount of deformation, and the stress transmission and dispersion caused by the unevenness of the bottom cushion

layer are relatively fast, with strong strain capacity. Using geotextile instead of granular material as the protective layer of geomembrane to protect the anti-

seepage layer of geomembrane from damage, reduce the grading requirements of cushion particle size, and provide drainage function. The friction coefficient

is high, which can prevent the sliding of the covering layer. Compared with pure HDPE film, the non-woven fabric in composite geomembrane has a higher friction

coefficient. Composite geomembrane can increase the slope ratio and reduce the footprint. Tear, puncture, and puncture have high mechanical strength. It has

a certain insulation effect, reducing 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, lowers project

costs, and shortens the construction period.
