Construction joints are deliberate separations or spaces built into structures, particularly in concrete, to accommodate movement, manage thermal expansion and contraction, and prevent uncontrolled cracking. They are crucial for maintaining structural integrity and are placed where concrete pours are stopped and restarted or where different sections of a structure meet.
Isolation joints These joints separate different parts of a structure, such as a slab from a wall, to allow for independent movement and prevent stress transfer.
Expansion joints These joints are designed to accommodate the expansion and contraction of materials due to temperature changes.
Contraction (Control) joints Similar to expansion joints, these are used to manage movement and cracking, but they are designed to control the location and direction of cracks that may occur due to shrinkage.
Slip Joints Allows one structural element to slide relative to another while maintaining load support.
Cold Joints Occurs when there is an unintended delay in pouring concrete and the new concrete does not bond perfectly with the old.
