Geo-Textiles
- Geo-textile is defined as any permeable textile material that is used with foundation, soil, rock earth to increase stability and decrease wind and water erosion
- Have been used from Pharaoh’s time during construction of roads
- Made of synthetic polymer (polypropylene, polyester, polyethylene and polyamides) or natural-synthetic composite polymer.
Applications
- Civil engineering applications-Roads, airfields, railroads, embankments, retaining structures, reservoirs, canals etc.
- Sand Dune Armoring- Geo-textile sand filled units to protect upland coastal properties from storm surge, wave action and floods.
- Geo-textiles have been used to protect hominid footprint fossils of Lateoli, Tanzania from erosion, rain and tree roots.
- Stabilization of slopes when quickly establishing vegetation is not possible.
- Natural geo-textiles of coir and jute can be used to establish vegetation, since these degrade into humus and provide erosion blanket of 2-3 and 1-2 years respectively
- Coir and jute are especially useful in containing wind erosion. Can be used in Chambal badlands, Thar etc.
