What is Geotextile ??
Define Geotextile? Geotextile is defined as a permeable textile material used in contact with soil, rock, earth etc as an integral part of the civil engineering project, structure or system.
It may be of natural materials such as jute, coir, cotton etc. Or of synthetic polymers such as polypropylene, polyamide, polyester, polyethene.

Geotextiles are an efficient effective and economic method of solving most of the geotechnical problems in roads.
The design engineer should be well aware of the possible problems and should use this relatively new tool for solving them.
For this, he should understand properties and capabilities of the geotextile material at hand.
