Seismic Activity Map
All over the world, bridges and buildings are being built in Seismic Active areas. These structures must be equipped with Modern Technology to protect the
Structures, and the people using them.

The Swivel Joint
TechStar developed a Swivel Joint in 2000, for Bridges being built in seismicZones.
Swivel technology allows transverse movement to occur incase the bridge faces an Earthquake.

The Hybrid Joint
A Hybrid Plate is welded or screwed onto the top of the expansion joint,
resembling a ‘Finger Joint’ Appearance.
The Hybrid Plate helps reduce the noise made by cars passing over the joint.
