BCI –COIR GEOTEXTILE IS BIODEGRADABLE
Coir is a natural organic product and organically biodegradable. The fiber decomposes slowly, making it perfectly suited for use as an erosion control blanket. The mechanical
strength of the netting declines at a rate depend on soil composition. Generally, BCI-Coir Geotextiles provides good support on slopes for about 5 years. This allows ample time for the natural vegetation to take over the job of holding the soil in place. When the BCI-Coir Geotextiles eventually disintegrates, it leaves only hums. There is no need for post installation work.
COIR IS AN ABUNDANT AND RENEWABLE RESOURCE
The Coir fibre is obtained from coconut husks. The coconut palm grows plentifully in southern India, where there is a long tradition of preparing the Coir fiber. BCI Coir erosion control blankets are well suited to the world demand for an environment friendly product.
BCI Coir Geotextiles in densities from 400 to 1,400g/sqmtr
♦ Matting density to meet soil pressure.
♦ Open surface percentage, allowing for new growth of vegetation.
♦ Capacity to control surface water.
♦ Requirements on landscape design and costs.
A higher density means a tighter mesh and less open area in the netting.
The heavier grades can be used on embankments and slopes where there is no or little vegetation. Other advantageous applications are on sky slopes and as a bottom reinforcing material in water courses. Coir has good properties for use under water. There the natural degradation is considerably slower, since micro organisms are generally less active.
The lighter grades of BCI Coir Geotextiles are suitable for prompt erosion control of all kinds of green areas. The netting can also be used over garbage dumps and mining areas, where land changes shape frequently.
