The difference between geotextile and composite geomembrane

1.Composite Geomembrane

Composite geomembrane is an impervious material made of geotextile and geomembrane. It is mainly used in anti-seepage engineering. Composite geomembrane is divided into one cloth, one film and two cloths, one film. Its width is 4-6m and its weight is 200-1500g/m2.

Its physical and mechanical properties such as tensile, tear and bursting are very high. And composite geomembrane can meet the needs of civil engineering such as water conservancy, municipal administration, construction, transportation, subway, tunnel, etc.

Composite geomembrane can be used in unconventional temperature environment because of the selection of polymer materials and the addition of anti-aging agent in the production process.

2.Geotextile

Geotextile, also known as geotextile fabric. It is a permeable geosynthetics made of synthetic fibers by needling or knitting.

Geotextile is one of the new geosynthetics, and the finished product is cloth-like. Its general width is 4-6 meters and its length is 50-100 meters.

Geotextiles are divided into spun geotextiles and non-woven geotextiles. Among them, non-woven geotextiles can be divided into short fiber non-woven geotextiles and filament non-woven geotextiles.

Geotextiles are widely used in geotechnical engineerings such as water conservancy, electric power, mine, highway, and railway.

3.Similarities and differences

Composite geomembrane and geotextile have the functions of filtration, drainage, isolation, reinforcement, and protection. But the composite geomembrane has a membrane structure. So it also has an anti-seepage function. This is what geotextiles don't have.
