mageba TENSA-RAIL RSU single-gap expansion joints allow movements of up to 350 mm and more. They consist of steel edge profiles and an elastomeric sealing fixed between the profiles. The joint‘s gap is protected by a cover plate from the invasion of dirt.
TENSA-RAIL RSU expansion joints are suitable for the use in railway bridges with and without ballast. The ballast either lies directly on the joint or, ideally, on an insulation mat introduced between the ballast and the bridge slab.
