Erosion Control

Erosion Control

Causeways on unsealed roads in the wet season are often susceptible to severe erosion.

Revegetation Contractors was contracted by Department of Defence – Army to stabilise three road causeways that could withstand “tank” traffic at the entrance to one of their training centres. After the necessary design was completed, Revegetation Contractors elected to install “Geoweb©” in the area to be treated – firstly, because of its ability to strengthen the load bearing capacity of the road while remaining flexible, and secondly, because of its inherent capacity to retain gravel in its cellular structure in the face of heavy water flows.

Given the dry conditions of the area, Revegetation Contractors was also required to select drought tolerant grass species for revegetation works in the adjacent training centre.
