Retaining Wall Alternatives

Retaining Wall Alternatives

The Vetiver System (VS) can be used for land rehabilitation. It is a cheap alternative compared to traditional methods, though is most effective when implemented in a ‘preventative’ way, where it is apparent that landslides are beginning or could potentially occur. After major landslides have already taken place, the VS can also be an incredibly useful tool in the stabilization and rehabilitation process; however if they are too severe, often combined solutions may be required where recommended designs may entail the Vetiver System (VS) along with other traditional methods such as geotextiles, gabion baskets, etc.

To prevent landslides or rehabilitate existing slips from further movement, the fibrous roots of the vetiver plant penetrate deep into the ground, surpassing the slip surface for cases less than three (3) meters deep. This action changes the overall shear strength of the slope, essentially providing a reinforced soil structure, and has been proven to increase overall slope stability by up to 40%. This can play a major role in preventing future landslides from occurring.
