Types of Concrete Joints and Placing Tips

Jun 16, 2019 · Concrete expansion joints are used to separate slabs and from other parts of the structure. Expansion joints allow independent movement between adjoining structural members, minimizing cracking when such movements are restrained. It allows for thermal expansion and contraction without inducing stress into the system.

How to Replace Concrete Expansion Joints | HowStuffWorks

An expansion joint is a material placed in the cracks (or joints) between slabs to protect the slabs from cracking when they contract and expand as the temperature changes. This material acts as a shock absorber, absorbing the stress from the slab's movement.
