mageba scope

In 2013, mageba installed several TENSA-MODULAR expansion joints of type LR3 and LR8 as well as TENSA-GRIP RS single gap joints for the Chongqing Dongshuimen Yangtze River Bridge.

TENSA®MODULAR expansion joints allow free movements in all directions and rotations about every axis. The largest joints delivered, type LR8, can accommodate movements of up to 640 mm.

TENSA-GRIP RS single gap joints can facilitate movements of up to 80 mm. The joints consist of robust steel edge profiles and replaceable elastomeric sealing profiles, which ensure long-lasting watertightness. The drainage of the joints is accomplished by the drainage system of the bridge deck.
