mageba TENSA-MAT expansion joints allow movements of up to 160 mm. They consist of watertight elastomeric slabs, clamped between two steel edge profiles which are anchored in the concrete. They form a continuous closed surface with the carriageway which reduces noise and vibrations and also prevents the trapping of debris and other foreign objects.


TENSA-MAT expansion joints are suitable for use in bridges in urban areas where noise should be minimized. They are also usefull for railway bridges with stone ballast beneath the track, and for joints which highly skewed joints that any gap would present a danger to cycle traffic.
