The scope of geotextile in the engineering field is very vast. The application of geotextile is given under the heading of the nature of work.

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 commercially viable alternative to the conventional systems. Geotextiles perform the filtering mechanism for drainages in earth dams, in roads and highways, in reservoirs, behind retaining walls, deep drainage trenches, and agriculture.

5. River, Canals and Coastal Works

Geotextiles protect river banks from erosion due to currents or lapping. When used in conjunction with natural or artificial enrockments, they act as a filter.

Geotextiles are permeable fabrics that are used in a variety of civil engineering and environmental applications. Here are some reasons why geotextiles are commonly used:

• • Stabilization: Geotextiles can be used to stabilize soil in roadways, embankments, and other construction projects. By placing a layer of geotextile between the soil and the construction material, geotextiles help to prevent soil erosion and provide added stability to the construction site.
  • Drainage: Geotextiles can be used as a filter layer to allow water to pass through while preventing the passage of soil particles. This is particularly useful in drainage systems where water needs to be channeled away from a construction site.
  • Separation: Geotextiles can be used to separate different layers of soil or other materials. This is particularly useful in road construction where a geotextile layer can prevent the mixing of materials and maintain the integrity of the road structure.
  • Protection: Geotextile fabric can be used to protect vulnerable surfaces such as geomembranes or other liners from damage. This is particularly useful in environmental applications such as landfill liners, where geotextiles can protect the liner from sharp objects and other potential sources of damage.
