Landslide Rehab & Prevention

Vetiver System for Landslide Prevention and treatment

Vetiver Grass Technology has been mainly used for the repair of landslide sites, rather than in the prevention under natural conditions.  For the repair it has worked well in a number of countries including Brazil and Venezuela. It has proven effective on road construction sites in many countries where it has prevented many slips on shallow cut and fill slopes. Vietnam’s Ho Chi Minh Highway is one such example where prior to application on the highway there were serious slips

Slope Stabilization in Itaipava‐Petropolis (Brazil)  The vetiver solution was a total success after a landslide in 2008. This article is particularly relevant now that the catastrophic landslides are more frequent and damaging.  PowerPoint Presentation    and  Paper

LAND SLIDES & PROTECTION This short series of images from Van Tran Tan of Vietnam gives shows how Vetiver System stabilized land slide prone slopes on the Ho Chi Minh Highway.

The Vetiver System can provide a low-cost solution for shallow landslide mitigation.
