It enables the modular joint to swivel and absorb the transverse movements of bridges.

Earthquakes are always problematic to bridges. The large displacements that earthquakes cause can destroy a standard modular expansion joint, making the roadway and bridge impassible. We developed the technology to permit the transverse movement that occurs during such seismic events.  With ‘swivel joint’ movements for seismic conditions are now provided, enabling the modular joint to “swivel” and absorb the transverse movements that occur during earthquakes or due to wind. The swivel modular joints are considered the highest quality in this area.  The swivel joints are capable of providing both longitudinal and transverse movements during seismic events enabling the bridge to remain open for all emergency traffic that is required at the time.
