Rock Drape

A Rock Drape is a protection system that utilizes wire mesh, cable netting or ring nets to help control rocks as they fall. The Rock Drape is anchored at the top and draped down over unstable slopes. This allows rocks to fall in a controlled manner, thus minimizing the potential to cause damage. The energy is reduced by containing the rocks and keeping them close to the rock face as they fall to the collection area at the bottom of the slope. A Rock Drape can be used in conjunction with other methods of mitigation to provide a long term solution to rockfall issues. If no catchment or collection area is available at the bottom, the drape may be pinned to the slope using rock bolts or dowels to hold the loose material in place.
