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.
