Coir geo textile is a natural solution to large scale soil erosion / soil degradation. It has achieved wide acceptance all over the world. As a natural product, Coir geo textiles are bio-degradable and environment friendly. Studies conducted in geo-textiles have indicated that coir is better preferred, as compared to jute or other natural materials owing to certain characteristics like durability, wat strength, hairy surface etc. It enables vegetation to take root on the applied area thus making the bonding of the soil very strong. They are ideal for application on hill slopes, road and rail embankments.

This is the simplest form of coir geotextiles and is manufactured on traditional handlooms using 2 shaft weaving techniques. Used primarily for erosion control applications, these are available in 10 varieties with fixed quality specifications stipulated by the Bureau of Indian Standards.
These 10 varieties are made available for different intensities of rainfall, types of soil, slopes of surface etc These varieties can be identified based on weight per Sq. meter, type of yarn no. of strands etc...  

b. Coir woven fabrics with loop construction

Primarily used for soil stabilization, this type is woven in rolls using technique of loop mat weaving.

c. Coir bags made with latex backed coir matting
This type is used mostly to control sea erosion and as a substitute for huge granite boulders which involve high labour and transportation costs. Designed to withstand powerful waves, thick ribbed matting with latex backing is used for this application. The bags are stitched with the latex facing inwards. The usual bag size is 6 ft x 4 ft.

Non Woven Geo textiles

a. Coco logs

Shaped like a wooden log, Coco Logs are coir fibre thickly filled inside tube shaped coir netting. The diameter of the Coco Log varies from 15 to 50 cms and come in lengths of 2 to 6 meters. These are mainly used for absorbing the impact of waves in erosion prone areas.The main area of application is stream bank protection against wave splashing and erosion control.  Advantages: The natural product combination will support the development of plants in distributed wet land areas. By the eco-friendly application of natural materials, we are able to restore nature which has been violated by other forces.

Coir logs are identified based on its density as low, medium and high.

b. Coir fibre beds

Here mesh mattings are stitched together to form a pouch and then filled with coir fibre. The ends are stitched to form fibre beds, the thickness of which vary from 10 to 25 cms as per the requirement. They are mainly used as wave energy dissipaters.

c. Coir needle felts

These are pads made by interlocking coir fibre through needling. These felt pads can be used for low cost acoustic control, air & water filtration, thermal insulation. and also for soil erosion control.  Specification of  CCGM (Three varieties, As per International standards)
