LOSKOP RETAINING WALL GROBLERSDAL
Problem Road Rehabilitation has been carried out on the N11 route to Groblersdal along much of the roadway. On selected sections of the road the toe of the mountain was blasted to achieve a widened carriageway. The blasting resulted in an unstable rock cut face, which was susceptible to erosion and the dislodgment of rocks was a hazard to motorists below.

the wall. The rock fill for the Terramesh® units was obtained
from crushed and blasted rock from the mountain. A concrete footing was constructed in order to align
the Terramesh® with the road. The colour of the rocks within the Terramesh® units
blended well with the surroundings giving it an aesthetically pleasing finish.
