Rockfall Hybrid Barriers/Attenuators combine rockfall barrier technology with the advantages of simple drapery to form an efficient passive system. The upper section of the rockfall hybrid barrier/attenuator absorbs the energy of the rock impact and the draped mesh guides the rock down the slope.

The energy of the falling rock is partially dissipated by the rockfall hybrid barrier/attenuator as it impacts the mesh panel. The falling rock is then contained and slowed between the mesh and ground surface as it continues to fall towards the bottom of the slope.

Due to lower maintenance costs, the rockfall hybrid barrier/attenuator is a cost effective solution. The raised post at the upper section allows rocks from above to be caught within the system, providing extra protection compared to standard simple drapery systems.

THE MACCAFERRI ADVANTAGE

• Less maintenance cost by reducing the repairs to do after impact
• No rocks to remove from the barrier after impact
• Innovative knot system allows HEA cable panel to absorb energy on impact
• Superior testing results: withstood repeated rockfall impacts with the least amount of damage when compared to 10 other (non-Maccaferri) rockfall mesh and cable net panels used within hybrid barrier/attenuator systems in the recent CDOT study, Colorado's Full-Scale Field Testing of Rockfall Attenuator Systems (Arndt, Ortiz, and Turner, 2009)
