Geotextiles are the porous fabric, which utilizes in alliance with the soil, which has the potential to filter, separate, protect. It is a strong fabric that employes in engineering projects. The stabilize loose soil particles and prevents erosion but they are mainly made up of polyester. Its sandbag can be 20m long. It’s amalgamation is been introduced by this material which is referred to as geogrids.
Earlier in ancient times, the textiles were used to support the foundations of the great pyramids. But they use it on the roadways to support and separate the different soil layers from one another. So, geotextile currently supports many of the civil engineering applications which include the roads, dams, railroads, canals, construction sites, etc. The various properties are namely mechanical, hydraulic and chemical. The fabrics come in three basic forms: woven, non-woven, and knitted.
The functions of geotextiles are:
Filtration
The balance geotextile to the soil system which allows the adequate liquid flow with the little soil loss across the plane of it over the lifespan.
Drainage
The capacity to wide nonwoven which is a structure that provides the direction for the flow of the water directs the plane.

Separation
It will isolate the different materials, the function of separation plays an important role.
Reinforcement
In reinforcement of geotextile, it is similar to the purpose of rebar in concrete. It uses causeway and roads are built over very badly categorized soils.
Sealing
The fabric can be infused with the asphalt or the other mixes to make it waterproof and is capable of limiting the flow of liquids in both directions. Afterward, the impermeable use to prevent the contamination of the soil or groundwater because of the pollutants which prevent the loss of potable water due to evaporation.
The advantages of geotextile are:
- Cost-saving material
- Increase construction speed
- Achieves supplementing
- Improve quality
The disadvantages of geotextile are:
- Because of the Seed germination, the soil temperature gets delay.
- Plastics sheeting is easily bang-up.
- Not suitable for areas that have heavy traffic.
- Blankets and mats are not satisfactory for the excessively stony areas.
The basic properties:
- Tensile strength
- Elongation
- Impact strength
- Stress crack resistance
- Heat resistance
geotextile fabric stabilizes the ground by spreading loads over a larger area. By being lighter, less expensive, and thinner than layers of gravel, it makes financial and environmental sense to use this around your barn, stables and arenas.
