Noise protection gabion with concrete core

SilentR® is a multi-chamber basket system consisting of the monotecR® locking rod system.

  • Combines attractive privacy measures with highly effective noise protection

The installation of a continuous concrete core in the middle chamber ensures the jointless construction of the sound insulation layer.

Sound-absorbing properties are obtained by filling the external chambers with coarse stones. For more demanding requirements, one of the external chambers can be filled with porous lava rock. This results in a high level of sound absorption.
