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.

Easy dimensioning with ATTERO software

Tested in large-scale field tests the ATTENUATOR is the first solution of its kind that can be efficiently dimensioned. This is done with the free online tool ATTERO.

Multiple impact capability

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

Extra safety due to high-tensile steel

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

Self-cleaning – low maintenance

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.
