Gabion Rock barriers form part of the passive range of solutions where the primary objective is to intercept rock falls. This follows the same principle used for embankments which are suitable for moderate gradients however where steep gradients are encountered and space becomes a premium then rock fences are preferred. A rock fall tunnel may be considered where the rock face is near vertical slopes or where the kinetic energy developed by the falling rock exceeds 3000kJ.
 
The height of barrier fence, location and the impact resistance requires a good understanding of:

• Likely size of detached rock
• Topography of the downhill slope and likely energy dissipation ability
• Level of maintenance proposed to clear debris from the fences

Furthermore the location of the fence should be at least 10m from a downhill structure to accommodate the deformation that takes place during impact.

BESKING offers a range of energy absorption fences from 500kJ to 5000kJ. These systems were developed after extensive research and testing which include full scale field tests in accordance with European guidelines (ETAG) to accurately replicate the energy of a specific rock size.
 
Rock fences consist of a number of components and accessories when combined provide the required energy absorption levels in accordance with the test certificate.
