Different Types of Geotextiles
There are normally three types of geotextiles. Geotextiles are fabric that permits water to pass through. Three categories are woven, nail punched, and heat bonded. Woven material looks like material that mail sacks are made of. Nail punched can be easily mistaken for felt. Heat bonded material looks exactly like ironed felt.
Geo textiles are used to retain granular soil and allow water to pass through and are occasionally also used to reinforce soils at sites that require rather rapid strengthening of soil.
Doing silt fencing involves a series of steps. The first step is to drive wooden or metal stakes well into the soil along a contour line on the ground. Then the fabric is put up along these stakes on their downward side. The bottom part of the fabric is supported on the downward side by entrenching it in the soil. This acts as a support for it. Now the fencing is ready for use.
Whenever water containing silt comes, the silt is retained on the upward side and water is let out. The let out water is bereft of silt and hence when it drains into the water bodies nearby they are not polluted due to the silt from construction activity.This new technology protects the water bodies around the construction site.
