Hazardous rocks and boulders may be exposed following significant weather events. Soil erosion and run-off may dislodge rocks and boulders previously held in situ by soil and vegetation. Once exposed, they may break free and roll down the slope, causing damage to vehicles and infrastructure.
Rocks that pose a hazard may be removed entirely and relocated to a safe place. Alternatively, there are various rock and boulder treatments available to reduce the potential hazard. These include methods to minimise the rock to an acceptable size. Rocks and boulders can also be stabilised using various methods.
