Rockfall impact attenuators

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.
