EXPANSION JOINTS

An expansion joint, or movement joint, is an assembly designed to safely absorb the temperature-induced expansion and contraction of construction materials, to absorb vibration, to hold parts together, or to allow movement due to ground settlement or earthquakes. They are commonly found between sections of buildings, bridges, sidewalks, railway tracks, piping systems, ships, and other structures.

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

STM supplies and installs these profiles, which may be according to specifications, trafficable, fire-rated, and water-tight. Our edge is to provide you with a cost-effective solution to avoid overspecifying the joint system and alleviate pressure on your budget.
