ATTENUATOR: Redirect and guide rockfall efficiently

The ATTENUATOR System is a modified rockfall drape providing particularly efficient protection. The upper part deflects the falling rock and the drape directs the rock to the designated runout zone. This lowmaintenance protection solution is used where high-frequency rockfall events are expected.

Dimensionable system

Extensively tested in largescale field tests and the first solution of its kind that can be efficiently dimensioned.

Self-cleaning barrier

Redirected rockfall is safely guided into the runout zone, allowing the rocks to be removed quickly in an area of easy access thus reducing costs. 

Multiple impact capability

The flexibility of the system ensures safety even after several impacts minimizing maintenance. 

High-tensile steel wire mesh

Protection against dynamic and pointed loads: Optimum impact load distribution to the flexible netting and anchors prevents puncturing and system failure.
