Expansion Joints

- Expansion Joints.Expansion joints are an important part of many structures, and they are designed to accommodate movement, reduce vibration, absorb shock, or accommodate misalignment of two connected components. Expansion joints are typically composed of a flexible material, such as rubber, silicone, neoprene, EPDM, and Teflon. The flexible material also helps provide vibration and noise reduction. Expansion joints can be found in many different structures, such as bridges, buildings, factories, water and wastewater systems, power plants, roads, etc. Expansion joints can also be used to save energy by preventing the unwanted vibration that can occur when components are connected.
