Coir Erosion Control Blanket

Coir erosion control blanket can be either woven or non-woven. Woven ECB is an open weave structure with large / small open mesh. Non-woven ECB is either needle punched or stitch bonded.These materials are useful in erosion control and re-vegetation on slopes less than 50 degrees or in channels, where water flow rates are between 1 and 4 m/s. The hairy nature of the yarn used for making the blanket breaks the falling raindrop into droplets, thus decreasing their erosive action. The material absorbs water, around 3 times its own weight. Coir geotextile lasts for 3 to 5 years and degrades to form humus which is useful for plant growth.
