1. The isolation effect:
Take geotextile separate different soil structure, make it not
fluctuating interface, let each layer structure separately, in
accordance with the requirements play their performance and the
overall effect.
2.Protective effect:
Geotextile can in soil or water protection and buffer effect.
3.anti-seepage effect:
Geotextile composite geotechnical material collocation, can avoid
liquid leakage, gases and vapors, ensure the safety of the
environment and buildings.

Product Application
1. Road Work
Geotextiles are widely used in the construction of the road. It
reinforces the soil by adding tensile strength to it. It is used as
a rapid de-watering layer in the roadbed, the geotextiles need to
preserve its permeability without losing its separating functions.
2. Railway Works
The woven fabrics or the non-woven ones are used to separate the
soil from the sub-soil without impeding the groundwater circulation
where the ground is unstable. Enveloping individual layers with
fabric prevents the material from wandering off sideways due to
shocks and vibrations from running trains.
3. Agriculture
It is used for mud control. For the improvement of muddy paths and
trails those used by cattle or light traffic, nonwoven fabrics are
used and are folded by overlapping to include the pipe or a mass of
grit.
4. Drainage
The use of geotextiles to filter the soil and a more or less single
size granular material to transport water is increasingly seen as a
technically and commerc
