Rockfall barries
Rockfall barriers are systems of protective wire meshes, wire ropes, backing and anchor elements and energy dissipators. During an impact, the system ensures that the energy of the falling rock is absorbed by energy dissipators.
Rockfall barriers are designed for a specific quantity of kinetic energy of a falling block that has to be safely absorbed. Their design is subjected to a complex laboratory and “in-situ” testing in which their reliability and resistance to a specific quantity of kinetic energy have to be proven.

Typically, these barriers are built in the base of the slope, making up a barrier between the slope and the area underneath which is potentially in danger because of falling rocks.
