Highwall concerns : Pit & Quarry

 · Control of the rock fall reduces its energy and contains the rocks to a catchment area where they can be collected and removed in a safe manner. Minimal maintenance is required if designed properly. The type of material used for the mesh design should be scrutinized to make sure it can manage potential rock falls without tearing and creating gaps in the system
