Geobrugg has said that it has achieved a world first following work with international experts which has led to development of an attenuator protection solution that can be efficiently dimensioned through design.
The new system has been put through a series of test in front of experts in a quarry in British Columbia, Canada.
According to Geobrugg, an attenuator is a modified rockfall drape where a rockfall is intercepted at the upper end and slowed down while the steel wire mesh drape guides the stones to the ground.
The company has said that this is the first solution to offer reliable and efficient dimensioning of an attenuator system and the live test demonstrated the new method, the rotating movement of the blocks caught by the system and active performance of the system itself.
Geobrugg worked with Canadian rockfall protection expert Duncan Wyllie to develop the design concept for the attenuator system. The company has said that the solution is practically maintenance free and can withstand multiple impacts for use where high-frequency rockfall events are expected.
