Architectural Expansion Joint

Architectural Expansion Joint - BnG 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
