Geo rolls & vegetation fascines
Geo rolls or vegetation fascines are strong flexible construction modules of a compact roll or coir web covered by an exterior Coir mesh netting, which aids in the stabilisation and revegetation of sites where sleepness or high exposure to waves or currents causes instability. Their configuration and density help them to maintain from without losing material. They also promote plant growth and microbial activity. In flowing water areas they facilitate new channel assignment. In standing water they initiates sedimentation, facilitate vegetation and dissipate induced wave energy, Geo rolls collect and hold mineral and organic particles, provide a physically stable substrate for root growth and gradually bio-degrade to leave a self-sustaining erosion control system.

Material Composition
The interior of the goe roll consists of 100% Coir fibre webs cross lapped or air layed, flowed by needle punching or stitch binding. The Fibber density greater than or equal to 1000 gsm. And widths of 220 mm. Upto 600mm. The substrate is then rolled into desired diameters.

Application Techniques of Coir
Site assessment
The first step in the application of Coir Geo-textile is to make a detailed study of the sites like, Slope Assessment, nature and consistency for the soil cover, the extent of damage, rainfall patterns, etc. to make the right and relevant choice of Coir Textiles for the site, as well as the seeds of saplings

Self preparation and laying Procedure
Slope Application: Soil type assessment/ Slope assessment/ Slope blanket slelction/Slope stabilization procedure. Channel Application: Online Assessment/Chankle liner slelection/Channle Vegetation selelction/proposed vegetation assessment/ Channle stablisiation proceedure. Shoreline application. Shore line assessement/shoreline blanket selelction/ Shoreline selelction/Shoreline stablisition
The ground has to be prepared by removing protruding stones, earth masses etc. and made reasonably even. Natural bulges can left as it is. Before doing any seeding, the prepared earth work needs to be relatively free of weeeds,s tones, roots, ticks, rivulets, gullies, crustings and caking.
After preparing the soil surface, the seeds have to be applied on the surface by broadcasting or by hydraulic means and the balnket/mat to be laid over the sees almost immediately

The seeds/plants have to be obtained suitable for your climatic conditions, preferably the local species as per clients. The seeds after germination should take up deep rooting system. The seeds should match the site soil conditions get optimum germination, root development, vegetation density and long term longevity.

The erosion control blankets are to be laid in the direction of the water flow starting from the top to the bottom. The top portion to be anchored in a cut trench and stapled or spiked to fix properly, similar is the case at the bottom of the slope, The blankets may be anchored with 11 gauge wire staples, size8”x2”8” (U shaped).

One or two dosed of sprinkling is recommended if the weather is hot and dry. First days the moisture leaes are to be properly monitored to facilitate easy germination of the seeds.
The blanket will protect the slopes against rain water. The vegetation to protect the slopes permanently and achieve greening effect on the surface.

Seedling/planting Methods
Quick Germination, sod forming, grass species be used whenever possible, while seeding, planting always match the seed/ sapling to be sued with the local soil conditions for optimum results. Standard seed broadcast methods are acceptable prior to erosion control blanket installation.
