Wabo®Modular joint systems effectively seal the joint gap, while keeping runoff water from passing through the substructure.
The box seal system provides the ultimate in sealed modular joint design and reliability. The strip seal system uses an inner-locking single layer strip gland that is easy to install in the field. Wabo®Modular joint systems are comprised of five important design features.
These features make the Wabo® Modular system tough, long-lasting, watertight and virtually maintenance free.
Field proven under the toughest bridge conditions everywhere in the world, the Wabo® Modular joint system is made to order in accordance with the highest fabrication standards and can be engineered to meet a variety of conditions and movement requirements.
Watson Bowman Acme designed, built and installed the first sealed modular joint system nearly three decades ago. This longevity comes in part from the basic design concept comprised of a steel multiple support bar system which combines the strength to support traffic loads with the flexibility to accommodate continual structural movement. Today, Watson Bowman Acme is the worldwide leader in the manufacture of large movement modular expansion joints for challenging long span bridge structure applications.
Wabo®X-cel Modular (Patent Pending) is capable of simultaneously allowing movement in the longitudinal, transverse and vertical directions while accommodating the structures service and seismic movements. It is designed to be functional after seismic excitation as well. The design of the Wabo®X-cel modular consists of supporting edge and center beams along with support bars, which span the open joint. The system is equipped with a mechanical control system, which assures equal spacing of each center beam. Sealing elements are utilized to ensure the integrity of a watertight system.
