Noise protection mats

ROBO-MUTE

Principle

The mageba ROBO-MUTE system reduces the noise which is generated by traffic in crossing an expansion joint and transmitted from beneath the joint. A mat of layered membranes forms a channel beneath the joint, trapping noise and directing it towards the channel’s ends, where its intensity is reduced by noise-absorbing padding.

Applications

ROBO-MUTE can be used in combination with all types of mageba expansion joints, and is particularly useful on bridges in residential areas and other noise-sensitive zones.
