Rockfall Barriers



 

The typical application is in rock masses in which the surface may break up into fragments with an approximate size of not less than that of a double-twist wire mesh and with an equivalent diameter of not more than 0.5 m.
For moderately steep slopes or where vegetation may take root, the barriers must be kept as close as possible to the slope face.
For steeply sloping or almost vertical slopes, the barrier, which is anchored at the top, is kept free along the slope, thereby letting the rock masses fall to the base of the slope but always keeping them between the rock slope and the barrier mesh.
The construction of a safe and continuous anchor system at the top and base of the slope is important. It must be possible to remove accumulated detritus from the base of the slope.
Double-twist mesh is the ideal solution due both to its flexibility in every direction and the fact that gaps in the mesh are avoided in the event of accidental breakage of some wires: this was an old and irresolvable problem for single-twist meshes (regardless of the type of wire used) which due to their nature cannot provide a similar guarantee.
