Geotextile

Based on manufacture, geotextile installation can be classified as follows:

Woven Geotextiles
Woven Geotextile are manufactured with the interlacement of two sets of yarns at 90 degrees in the weaving process. These geotextiles have high strengths and low elongations at rupture.

Nonwoven Geotextiles
Nonwoven geotextiles are made from staple fibres or continuous filaments. They are thicker than woven and are produced using the following bonding techniques:

• Needle punching

• Thermal bonding

• Chemical bonding

Knitted Geotextiles
As the name implies, knitted geotextiles are manufactured with the interloping of one or more yarns in the knitting process. These geotextiles have low strength but are highly extensible.

Stitch-bonded Geotextiles:
These geotextiles are manufactured by interlocking yarns or fibres or both, bonded by sewing or stitching. Stitch-bonded geotextiles are strong, heavyweight, and can be produced rapidly.
