Vetiver Grass - Slope Stabilisation
Vetiver Grass has been used to stabilise the slopes of over 200km of the Hi Chi Minh Highway in Vietnam. It has proved to be very successful over the last 14 years, when many of the traditional hard construction has failed to cope with the run-off from typhoons. Vetiver Grass is considerably cheaper to install and requires little maintenance once established. Vetiver slows the run-off allowing the rain to penetrate the ground, preventing slippage of the soil.
