How To Select And Use The Correct Geotextile Fabric

The use of the fabrics in many applications across the globe is greatly enhanced by geotextiles, a developing field in civil/construction engineering and other domains. In comparison to conventional road construction techniques, geotextile fabric is proven to be more cost-effective. There are several types of fabric produced: woven, needle-punched, heat-bonded, non-woven, integrated loops, and tufted loops. Geotextiles are strong, breathable, and long-lasting materials. These materials are intended to promote soil stabilisation and ground support in a specific location and have the capacity to segregate, filter, reinforce, protect, or drain. typically constructed from jute fibres or yarns, polypropylene, polyester, or both.

 

What is Geotextile and what are its types?

A synthetic permeable cloth called geotextile is used to enhance the properties of the soil. When employed in conjunction with soils, it has the capacity to separate, filter, reinforce, protect, and drain. For many infrastructure projects, including highways, harbours, landfills, drainage structures, and other civil works, geotextiles are the perfect material.

 

Types of Geotextile

Geotextile manufacturers broadly divide Geotextile into 3 categories

  • Woven Fabric Geotextiles

Geotextiles are often woven and produced using methods that are comparable to those used to weave regular garment textiles. Two pairs of parallel threads or yarns occur in this type’s distinctive pattern. Warp refers to the yarn that runs parallel to the length, and weft to the one that runs perpendicular to it. 

  • Non-Woven Geotextiles

Short staple fibre or continuous filament yarn are used to make non-woven geotextiles. Fibres can be joined together mechanically, chemically, or thermally, or a combination of these methods. The thickness of geo-fibres achieved through mechanical interlocking, chemical, or thermal bonding ranges from 0.5 to 1 mm, but the thickness of chemically bonded nonwovens is typically in the range of 3 to 5 mm.

  • Knitted Geotextiles

The procedure of weaving a number of yarn loops together results in knitted geotextiles. All knitted geosynthetics are created by combining the knitting technique with another geosynthetics production technique, such as weaving. Other geosynthetic materials utilised include geonets, geogrids, geo-cells, geomembranes, geocomposites, and others. Each of these materials has unique properties and usefulness for certain applications.

 

Applications of Geotextiles:

  • Separation

Between two layers of various materials, such as two distinct types of soil, new construction and dirt, or new and old pavement, fabric is placed. Although there are subtle differences, separation and stabilisation are occasionally used synonymously.

  • Stabilisation

In stabilisation, a cloth is placed on top of a very compressible substance. This substance is typically soft, moist earth. Here, the geotextile allows water to percolate through the porous soil and into the drainage material. As a result, the basement layer is strengthened and made into a more reliable base by consolidating it.

  • Reinforcement

Instead of strengthening the bottom layer as it does in stabilisation, the geotextile works as a source of strength in reinforcement.

  • Filtration

Similar to stabilisation, geotextile infiltration is used. In both situations, allowing water to escape from the covered layer is the primary goal. This application’s objective is to drain water while obstructing the passage of any fine particles, including soil. Combining a filter behind the geotextile allows for this.

  • Moisture Barrier

This application is virtually exactly the opposite of the ones mentioned above. The geotextile is utilised in the moisture barrier to stop water instead of allowing it to pass through. Applying an asphaltic suspension achieves this.  

  • Drainage

In order to provide seamless transmission, geotextile material can help collect water or gas and then move it along its plane. This procedure, which is also known as the drainage function, can be quite useful in drip drains as well as chimney drains.
