Passive Rockfall Barrier System or Rockfall Catch Fencing consists of I-beam posts spaced at certain intervals with a wire rope support system running from post to post with special friction devices placed in the support ropes. Then wire rope nets are attached to the support system and backed with a wire mesh. All of the anchors used in this system must meet required pull-out strength as determined by the rockfall energies the system will be absorbing.
This type of system is generally used where there is sufficient catchment from the toe of the slope to the area being protected. The location and height of fence will be largely dependent on the topography of the face and space constraints at the foot of the slope. The fence’s energy absorption capacity will depend on the mass of falling rock, its likely trajectory and required confidence levels. There are several types of installations that can be utilized depending on rock size, velocities and bounce heights to control and stop the rockfalls. These systems have been extensively engineered and field tested to assure they function as required.

Passive Rockfall Barriers System or Catch Fencing are installed as a measure to contain falling rock. Passive systems, in contrast to active systems, allow rock movement to occur but focus on preventing rockfall from reaching roads, railways, working areas, and other areas being protected. Protection is done by retaining, controlling, and catching rockfall events. Passive systems are often the most cost-effective solution as some rockfall source areas are not accessible.
