Rockfall Barriers are flexible rockfall catch fences used to intercept and stop falling rocks in rockfall hazard areas arising from technical, topographic or access conditions.
The fences are made of a complete kit of components consisting of a catch net downhill of the barrier posts. The fences vary in height and length, and are capable of absorbing impacts of high kinetic energy.
The posts act independently from the net. If a post is hit by a falling rock and damaged, the remaining posts take the additional forces, ensuring that the system’s performance is not compromised. During impact, the system ensures that the energy of the falling rock is dissipated and the rock is prevented from moving any further.
