Wabo®MDM TransFlex

The Wabo®MDM TransFlex is a unique multi-directional movement (MDM) segmental plate expansion joint assembly designed to accommodate large differential displacements, rotations and service movements as well as seismic movements. 

The simplistic design of the assembly is comprised of four main design components: the deck plate, the elastomeric segmental panels, the support plate and the welded channel/box assembly.  Unlike other large movement capacity expansion joint technologies, Wabo®MDM TransFlex shifts the expansion component away from the critical joint opening and onto the deck surface. This shift increases the service life of the elastomeric segmental panels. 

Wabo®MDM TransFlex is installed in modules. The module design accommodates ease of installation, component replacement as necessary following damaging seismic events, and allows maintenance crews to minimize the impact to traffic and perform inspection by closing one lane at a time.
