1. Expansion Joints

2. Expansion Joints...What are they? An expansion joint is an assembly designed to safely: *absorb the heat-induced expansion and contraction of various construction materials,heat-induced expansion *to absorb vibration, *to allow movement due to ground settlement or earthquakes.

3. Where are they found? They are commonly found between sections of sidewalks, bridges, railway tracks, piping systems, and other structures.sidewalksbridgesrailway tracks

4. What happens if you don’t have an expansion joint? Before expansion joint gaps were built into these structures, they would crack under the stress induced.

5. What do they look like? The expansion joint can be as simple as a caulked separation between two sections of the same materials.

6. Expansion joints Necessary for many common structures and buildings. Help in heat induced expansion and contraction, absorb vibrations and allow movement
