An expansion joint or movement joint is an assembly designed to hold parts together while safely absorbing temperature-induced expansion and contraction of building materials, and vibration, or to allow movement due to ground settlement or seismic activity. 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 due to other heat sources. Before expansion joint gaps were built into these structures, they would crack under the stress induced.
CATEGORIES OF EXPANSION JOINTS
Joint covers and compression profiles
The clips affixed, adhesive or folded building expansion joint covers are designed to protect and conceal the facade, wall, floor, and ceiling expansion joints. Aesthetic, decorative, and economic they are fast and easy to install.
