TENSA-MODULAR modular expansion joints by MAGEBA allow movements in all directions and rotations around all axis. They can be used for small (160mm) and bigger (2.000 mm or more) movements. The whole movement of the board is divided by the areas between the horizontal beams of the surface. These areas are sealed with elastomeric and waterproof profiles. This way, beams’ movements are controlled with an elastic control system. LR-LS joints have on their surface “sinusoidal plates” that reduce by an 80% the noise of the traffic over them.
TENSA-MODULAR expansion joints are used when the movements of a bridge exceed the capacity of a unicellular joint. The waterproof system, invented by MAGEBA years ago, is designed in a modular base, so it can be tailor-made to meet the specific needs of each structure.
