Rockfall impact attenuators - intercept and guide rockfall safely
Rockfall Impact Attenuator Systems are a rockfall protection solution combining rockfall drapes and flexible rockfall barriers. The hybrid system is used as a passive protection measure: The cable net barrier breaks the fall and the drape steers the rocks into the runout zone - it works as a deflector. The Attenuator System combines the proven strengths of both the barrier and drape to provide low maintenance protection. See also the Hybrid Drapery section from Rockfall Characterization And Control, TRB (Transportation Research Board), 2012.
No maintenance work required: Intercepted rockfalls are safely guided into a runout zone, allowing them to be removed without incurring additional costs orspending excessive time.
Two tested technologies in one
Geobrugg's proven rockfall barriers and drapes combined in 1:1 field tested solution.
Multiple impact capability
Elastic barrier: The flexibility of the system ensures safety even after several impacts.
High-tensile steel wire mesh/net
Protection against dynamic and pointed loads: Optimum impact load distribution to the netting (TECCO®/SPIDER®/rolled cable net) and anchors prevents puncturing and system failure.
