Architectural Expansion Joints

SCON Expansion Joint or movement joint is an assembly designed to safely absorb the heat– induced expansion and contraction of construction materials, to absorb vibration, to hold parts together, or to allow movement due to seismic events.

Building faces, concrete slabs, expand and contract due to warming and cooling from seasonal variation, or due to other heat sources. Before expansion joint gaps were built into these structures, they would crack under the stress induced

Why expansion joints are provided in buildings?

In building construction, an expansion joint is a mid-structure separation designed to relieve stress on building materials caused by building movement induced by: – thermal expansion and  contraction caused by temperature changes, – sway caused by wind, – seismic events, etc.

What is an expansion gap?

When installing laminate or hardwood flooring you should leave a space between your floor and the baseboard or wall. This space is called expansion gap and allows the laminate or wood floor to expand or contract.
