Expansion joints in concrete.

Nov 25, 2023 · A concrete expansion joint is a planned point of separation between two concrete slabs or structures that allows movement due to thermal expansion and contraction. They are purposefully placed separations that interrupt the concrete to prevent cracking. Concrete naturally expands and contracts with changes in temperature.

Expansion joints in concrete. Things To Know About Expansion joints in concrete.

Expansion joints are flexible material that runs along a joint or gap in slabs and other concrete structures. An expansion joint assembly is designed to absorb the expansion and shrinkage of the concrete, that naturally occurs due to change in temperatures. Understanding the need for expansion (or control) joints is necessary to install them ... Expansion Joints. Expansion joints are an integral part of any concrete pour; without them, concrete is likely to crack and fail. As concrete heat up it expands and as it cools it contracts.

It is placed between the concrete and whatever the concrete abuts, allowing independent movement between these structures. Expansion joints also absorb vibrations and permit soil movement as a result of earthquakes. Expansion joints are what keep concrete slabs stable and solid by accommodating thermal expansion and contraction, foot and equipment traffic, and heavy loads.
