Woven or knitted natural fibre products (coir or hemp typically), used for short term erosion control measures before the establishment of permanent vegetation.
Erosion control netting and other products which enable the quick establishment of vegetation are typically used on slopes and channels subject to erosion from wind and water action or newly exposed earthworks for which a ‘soft’, landscaped surface is required.
Specifically, erosion control netting comprises biodegradable mesh-like products which will disappear in one to five seasons depending on the material and hence are suitable for the establishment of low growing vegetation.
The longer lasting products, typically made of coir, can be used for lining of watercourses and ponds and other applications requiring mid term abrasion/erosion protection. The jute products, degrading in one growing season, are specifically designed to help in the establishment of grass/turf.
All erosion control nets work by providing some mechanical anchorage to top soil/sediments and seeds. Jute can hold many times its weight in water, hence can be used in conjunction with hydraseeding for the quickest greening of dry embankments.
