Rockfall Netting
Rockfall netting is a steel woven hexagonal opening wire netting which is used to prevent rocks and debris from falling onto roads, railways and other structures.
Rockfall netting is unrolled. or "draped," over the slope and secured with anchor bolts. Over time, rocks and debris will fall to the foot of the slope behind the steel mesh drapery. Rocks can then be collected in a trench of suitable dimensions, at the foot of the slope.
If desired, the mesh can be secured both at the top of the slope and at the foot of the slope with high strength cables. In this instance it is good practice to allow the lower cable to be loosened, in order that the collected debris can be removed safely.
