THIS SYSTEM IS USED WHEN THE ROCKS
LIABLE TO FALL AND THEIR FRAGMENTS
ARE NOT SMALLER THAN THE OPENING IN THE MESH,
AND NOR GREATER THAN 0.5 M IN DIAMETER
On moderately steep slopes, or where vegetation may grow, the mesh will be placed as close to the slope as possible. On very steep slopes, or those near to vertical, the mesh must be anchored at the head of the slope, not to the actual rock face, because thus, the rocks may slip between the slope and the mesh and be retained at the foot of the slope.
The key factor is thus to have continuous, safe anchorage at the head of the slope so the fallen rocks are deposited at its foot.Triple Twist mesh is the ideal solution because it provides flexibility in all directions and, even though one of the wires may break, the mesh does not unravel as would happen with Simple Twist mesh.
