Expansion joints are designed to accommodate the natural movement of building materials caused by temperature fluctuations, moisture changes, seismic activity, and other environmental factors. These joints are strategically placed in structures such as bridges, roads, pipelines, and buildings to absorb and relieve stress, preventing cracks, warping, and other damage. By allowing for controlled expansion and contraction, expansion joints help maintain the structural integrity and longevity of construction projects, ensuring safety and durability over time.
