What is geotextile and what is its function?

Geotextile is composed of high-strength fiber tow and non-woven fabric, and its process is that the fiber tow is arranged in a straight line to give full play to the stress of yarn. The non-woven fabric is placed under it and wrapped and bound by warp knitting technology, so that the fiber tow non-woven fabric is consolidated together, which not only maintains the filterability of the non-woven fabric, but also has the strength of the woven fabric.

The function of geotextile:

1, isolation

Geotextiles are used to separate different soil structures, form a stable interface, separate various layers of structures, and play their respective characteristics and overall functions as required.

2. Protective effect

Geotextiles can protect and prevent soil or water.

3. Seepage prevention

Geotextiles and composite geotextiles can prevent liquid leakage and gas volatilization, and protect the safety of the environment or buildings.

Extended data

Geotextiles are widely used in geotechnical engineering such as water conservancy, electric power, mines, highways and railways.
