Geotextile For Soil Stabilization

Geotextiles are created from chemically resistant synthetic fibres so that biodegradation can be prevented. These fabrics are either matted or knitted together by needle punching or heat-sealing. Although all geotextiles happen to be permeable their hydraulic and mechanical properties tend to vary quite a lot. Geotextiles are used for soil stabilization in civil construction projects. The most prominent areas of such applications are roads, drainage structures, and landfills, to name a few.

The functions of geotextiles

Following are the main functions of geotextiles:

· separation

· filtration

· drainage

· reinforcement

· protection

Geotextiles are often used to separate several layers of soil with varied particle sizes as this helps each such layer to retain its function and integrity. They also act as filters by retaining soil particles as they allow water to flow through the soil. They are also capable of acting as drains by discharging and gathering gases or liquids that the structure does not need functionally.

A comparison of woven and non-woven geotextiles

Woven geotextiles are created by weaving polyester or polypropylene fibres. On the other hand, non-woven geotextiles are more like felts but they are also made from the same fibres. Woven geotextile fabrics that are used for soil stabilization primarily play the role of reinforcement and separation. Non-woven geotextile fabrics are used mostly for filtration and drainage.

Common areas of application for geotextile soil stabilization fabrics

These fabrics are used mostly for embankments, steepened slopes, and retaining walls. By using geogrids or/and high-strength geotextile you can construct embankments on soft soil foundations. You can also use geotextiles along with geogrids for the purpose of reinforcing steepened slopes. The same combination can also be used for creating retaining walls or reinforced soil walls.

Conclusion

These days, you get a lot of companies that are offering factory-seamed geotextile soil stabilization fabrics. These are created according to customized lengths and widths. These companies also offer you a wide array of seaming capabilities such as nonwoven, monofilament wovens, and slit-film wovens to high-strength and high-performance PET (polyester) and PP (polypropylene) geotextiles. You can also be sure that you would get re-rolling and off-line slitting along with quick delivery to your job site from these companies.
