Expansion joints are cuts in concrete or other flooring that allow for movement and reduce the risk of cracks and other damage
Purpose
Expansion joints are used to manage stress and movement in industrial flooring, such as in warehouses, production halls, and parking lots. They help prevent cracks, chips, and other damage that can occur due to temperature changes, heavy loads, or soil shifts.
How they work
Expansion joints are full-width cuts in the concrete that isolate different parts of the slab. This allows the concrete to expand and contract without straining certain areas more than others.
Maintenance
Expansion joints should be sealed and filled with a flexible joint sealer, but should not be epoxied or coated over. Routine maintenance is important to keep floors safe and extend their life.
Installation
Expansion joints are cut in different ways depending on the weather. In hot weather, they are typically cut while the concrete is still wet, while in cooler areas they are cut after the concrete has hardened somewhat
