What is an expansion joint?

An expansion joint is a structural component designed to absorb movements and vibrations in a building or other infrastructure caused by heat, seismic activity, or settlement. Expansion joints are commonly used in bridges, buildings, and pipelines to allow for the expansion and contraction of the materials without causing damage.

Expansion joints are typically made of flexible materials such as rubber, neoprene, or metal, and are installed in between sections of the structure to allow for movement in multiple directions. They can be designed to accommodate various types of movement, including linear expansion and contraction, lateral shifting, and angular rotation.

In addition to allowing for movement, expansion joints also help to reduce stress on the structure, extend the lifespan of the building or infrastructure, and improve overall structural integrity. Proper design and installation of expansion joints are crucial to ensuring the longevity and stability of a structure.

Overall, expansion joints play a crucial role in preventing damage and maintaining the safety and integrity of buildings and infrastructure in various applications.
