In building construction, an expansion joint is a mid-structure separation designed to relieve stress on building materials caused by building movement. Building movement at expansion joints is primarily induced by thermal expansion and contraction caused by temperature changes, sway caused by wind, seismic events, static and live load deflection.
We have installed miles of vertical and horizontal expansion joints in sidewalks, hospitals, commercial buildings, parking garages, airports, and industrial facilities.
Expansion joints arise both in the external concourse and between airport terminal buildings and elevated roadways. Often such roadways are sub-divided by expansion joints and joints are also found between elevated roadways and link-bridges to multi-story parking garages.
