Madagascar - The Ilmenite Project

Sunday, November 9, 2008

Hydromulch (Pty) Ltd has been involved in a major sand fixing, erosion control and slope stabilisation undertaking along newly constructed roads at the Rio Tinto/QMM Ilmenite Project at Fort Dauphin in Madagascar. Wind blown sand was a major issue and a decision was made to use barrier netting and Vetiver grass hedgerows as erosion control protection on the slopes of the excavated Ehoala dune areas, prior to hydroseeding with local grass species.

It was estimated that the erosion control and vegetation reinstatement programme as a whole would require about two million Vetiver plants! The complete story with many valuable photographs was published in the July/August 2008 issue of Environmental Management and can be found here.
