Green carpet landscapes



        To reclaim the landscape at a project construction site and concern for the environment promotion Geo-green Erosion Control Blanket was introduced, so as to enable vegetation taking early hold in gripping the deep excavated soil together. Made out of coconut fiber, these blankets not only retain water for longer periods but over a time period gradually biodegrades naturally to fully blend with the soil conditions. Rock soils and other mud dug out from deep tunnels for the projects are normally sterile towards vegetative growth till weathering over a long period of time enables plant growth at the muck dump yards. For natural regeneration to reclaim such extreme soil conditions, vegetation requires at least two, if not more growing seasons to succeed.


         To over the problems of re-vegetation, to stabilize slopes and to check erosion, undulation of the dump yard slopes are first leveled before a layer of fertile top soil is laid over it. To prepare a rich top soil, ready to use soil preparations are imported, mixed at a 60:40 ratio with existing soils and manure is added to obtain a healthy and plant nutritious soil layer. Seeds of locally prevalent plants are mixed into the top layer before a Geo-green Erosion Control Blanket is laid out on the slope. .The green blanket is designed and developed to provide solutions to erosion control problems and slope stabilization.

       Besides the seeds planted, cutting and plants of species such as Hopseed  - Dodonaea viscosa, Silver Oak- Grevillea robusta, Bougainvillea and Subabul- Leucaena leucocephala are planted onto the treated slopes.
