Product Description

COIR EROSION CONTROL BLANKET

Introduction:

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.

Application:

  • Erosion control and slope stabilization of Hill Sides-Ski Slope.
  • Protection of High embankments of Road, Railway, Water Reservoir
  • Facial in reinforced earth slopes.
  • Protection of River and Canal Embankments, Wave Energy Absorber.
  • Creation and Protection of Dunes. Wind erosion Control.
  • Re-vegetation and forestation projects.
  • Restoration of ecology, wetland areas, degraded lands, landslide areas.
  • As eco-friendly night covers in waste dumps.
  • Landscaping Waste Dump Areas.
  • Protects geosynthetic installations from exposure to UV and vandalism.
