Wire mesh netting is often used to prevent rock and debris from falling on to roads, railways and buildings. This solution can also help to establish vegetation.
Those simply made by netting laid over the soil. When place on steep hills or rocky slopes they prevent the fall of loose stones as well as superficial slides.
They are called passive defenses as they simply support the weight of the stone and prevent the movement. Otherwise, those rocks when falling, would acquire speed and kinetic energy and become uncontrollable unless very expensive and complex structures (the active defense) are available.
Maccaferri rockfall mesh has the same characteristic as that used for gabions and Reno Matresses. Thanks to the double-twist weaving it is able to withstand the force of falling rocks and, unlike chain-link mesh, does not unravel should some of the wire break.
