Geotextile:

Geotextile are the parts of technical textiles that will lead the next generation textile. Geotextiles are permeable fabrics that, when used in conjunction with soil, have the ability to separate, filter, reinforce, protect or drain. Geo textile is used in civil construction projects to improve soil properties. Geo-textiles helps to unstable soils so it changes the properties of the soil and makes it suitable for construction of buildings in weak and inefficient places. Geotextiles are ideal materials for roads, ports, landfills, drainage structures and other civil projects. Geotextile products are mainly made of polyester, polypropylene, polyamide.

Common Application of Geotextile:

Geotextiles can also be used in many common applications such as-

  1. On the airport runway uncovered and curved road.
  2. Landfill and stone base on the road.
  3. Build sidewalks and sand drainage layers.
  4. In the construction of parking lots and curved spaces.
  5. In green areas and in the construction of recreational spaces.
  6. In the construction of structure of the wall.
  7. Construction of duct bank and pipe trench.
  8. Geotextiles are widely used in agriculture.

Functions of Geotextile:

Geo-textiles are commonly used to develop soil properties such as roads, dams, pipelines, and large structures in the ground. There are different types of geo-textile materials, including open-mesh, mesh-woven, and closed-fabric or non-woven fabrics. Various geo-textile materials are used for separation, filtration, extraction, reinforcement, etc.

Geotextile for Separation:

When a geo-textile is installed between two different soils, the separation characteristics of the geo-textile play an important role. In this case, the geo-textile will separate the different components in order to achieve the required soil properties. The main purpose of using such geotextiles is to prevent the geotextiles from mixing with the soil when the water level reaches the soil.

In road construction, for example, fine sub-grades have to be collectively separated from the coarse soil aggregate at the bottom. By this way keeps the drainage properties of the soil become intact. Those geo-textiles have special permeability properties to prevent soil contamination which allows moderate flow of water without compromising the strength and structural strength of the road.

Geotextile for Filtration:

Geotextile is used to reduce water from both sides by filtration. This geotextiles can be oven or non-woven and prevent fine aggregates soil from moving between the soil layers. Geotextiles can be used for both vertical and horizontal applications, solving drainage problems around houses and along roads and bends.

Geotextile for Reinforcement:

The geotextile can actually strengthen the soil or it can increase apparent soil support. The strength of geotextile depends on its design which is based on a few key factors. Such as-

  • Abrasive capable
  • Ability to accept loads
  • The function of the rain force in this concrete is incomparable.

Geotextile for Extraction:

A geotextile fabric can block pitch or other solutions and is able to limit fluid flow in both directions. Contaminants can prevent soil or groundwater contamination above contaminated soils.
