Wabo®Modular System STM 900

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.
