Product Description
Polyester filament geotextile is made directly by spinning and needle-punching and consolidating polyester filaments, it's made by forming and consolidating polyester filaments, the fibers are arranged in a 3D structure. Polyester filament non-woven geotextile has excellent heat resistance and light resistance, even if it is exposed to an environment of nearly 20 degrees for a short time, its performance is almost unchanged. After a large number of tests and practices, the polyester filament non-woven geotextile has long-term corrosion resistance to various natural soils, moisture and microorganisms.

Features
1. Separation; Polyester Filament Geotextile will prevent two soil layers of different particle sizes from mixing with each other, as is illustrated the image below.
2. Drainage; Polyester Filament Geotextile will efficiently collect superfluous water from structures, such as rainwater or surplus water, from the soil and discharge it.
3. Filtration; Polyester Filament Geotextile is an ideal interface for reverse filtration in the soil adjacent to the geotextile, in all soils water allowa fine particles to moved. Part of these particles will be halted at the filter interface; Some willbe halted within the filter itself while the rest will pass into the drain. The complex needle-punched structure of the geotextile enables the retention of fine particles without reducing the permeability of drain.
4. Reinforcement; Heavy geotextile can be used to reinforce earth structures by means of fill materials. Thanks to their
high soil fabric friction coefficient and high tensile strength, they are an ideal reinforcement solution.
5. Protection; Polyester Filament Geotextile is an ideal protection from erosion of earth embankments by wave action, currents or repeated drawdown. A layer of geotextile can be placed so as to prevent leaching of fine material. They can be used for rock beaching or as mattress structure, it can even easily be placed under water.
