Soil erosion  removes the top soil particles from one site and redeposit in another site. It creates harmful effects to both sites. Major erosive forces are runoff and wind. s

Global soil erosion destroys over 12 million acres of land in each year. Soil erosion is a naturally occurring process, but human activities, such as construction clearance, greatly increase this process. Soil erosion damage to the environment. Most prominent damages are washout of nutrient of soil resulting arid areas, mud accumulation in reservoirs and damaging to the irrigation systems. The removal of vegetation exposes soil to the erosive forces of wind and water resulting in the loss of topsoil, minerals and nutrients. These losses result in costly cleanups and loss of land productivity. Environmental concern and the rising cost of erosion damage have become serious considerations in all development projects and land management practices.

Geotextiles have been named as Best Management Practice by many Environmental and Governmental Organizations in helping reduce soil loss and establish new vegetation. Coir Geotextiles are widely used for civil engineering applications and  slope stabilization applications. Coir Geotextiles have the mechanical strength necessary to hold soil in place and prevent erosion. The nettings break up the runoff and dissipates the energy of flowing water. Coir also promotes the establishment of new vegetation by absorbing water and preventing  drying out of the top soil and seeds.

Geotextiles are  anchored into place to provide a continuous sheet over the exposed slope or surface. This sheeting reduces raindrop impact, runoff velocity and surface erosion on disturbed soils. It can also protect new vegetation and promote in growth and establishment of vegetation by retarding evaporation of soil moisture.

Coir Geo-Textiles  are being effectively used for improving soil behaviour, preventing soil erosion, and in helping consolidation of soil. Coir as a 100% organic and bio-degradable fibre, with great longevity, has a definite edge over synthetic geo-textiles, in the environmental aspect. The greatest advantage is that it provides an ecological niche for rapid establishment of vegetation.

Coir geo-textiles are in range of woven and non-woven varieties available for bio-engineering, including geo meshes, girds, geo beds, anti-weed blankets, needled felts, erosion control blankets, and coir/ water logs.

Coir geotextiles lasts longest amongst the natural ones. Moreover, when it does degrade after five years or so, it forms humus and enriches the soil. Coir geotextiles are naturally resistant to rot, moulds and moisture so they require no chemical treatments; they retain water and prevent the drying out of topsoil; and they resemble natural soil in their ability to absorb soil radiation so the tender plants never get heated excessively.
