Expansion Joint
An expansion joint is a special gap built into construction projects that allows buildings, bridges, and other structures to safely move and flex without breaking. Think of it like the spaces between segments of a bendy straw - these gaps help structures handle temperature changes, ground movement, and other forces that could otherwise cause cracks or damage. Construction professionals need to understand these joints because they're crucial for building safety and longevity. You might also hear them called "movement joints," "construction joints," or "isolation joints." These are all referring to the same basic concept of creating controlled spaces that prevent structural damage.
