What is a concrete expansion joint?
Before discussing Concrete expansion joints, we need to understand what an expansion joint is and the benefits of having a proper expansion joint. A concrete expansion joint is a gap (breathing space) that allows the concrete to expand and contract when the temperatures drop below a certain degree. This allows the concrete to move without causing stress, which can lead to cracking.

Benefits of Concrete Expansion Joints
Concrete expansion joints are necessary for the health and longevity of your sidewalk and driveway. Our Concrete Elite Expansion Joint Sealant is a superior chemical makeup formulated for expansion joints. It's a 100% RTV silicone sealant that is UV resistant, flexible, and durable. An excellent concrete expansion joint sealant shouldn't get brittle, crack, or fade over time. When it comes time to seal a Concrete Expansion Joint, you must ensure that the joint is clean of any grass and debris. Then place your foam backer rod if you choose to use it. Next, apply a bead of silicone followed by light tooling. Once the silicone has fully cured, you will have a waterproof rubber barrier to protect your investment.
