What Happens When Concrete Freezes?

All concrete must be protected from freezing until it has reached a minimum strength of 500 pounds per square inch (psi), which typically happens within the first 24 hours. If concrete freezes while it is still fresh or before it has developed sufficient strength to resist the expansive forces associated with the freezing water, ice formation results in the disruption of the cement paste ...

Winter Frost and Concrete Damage Lift Right Concrete

When the ground freezes, so does the water trapped within your concrete slab. As this happens, it expands and puts pressure on the slab from within. This compromises the slab’s structural integrity and leads to damage. Once the weather warms up and water in the slab begins to melt, the concrete can flake and crack. With successive freeze and thaw cycles, like we experience here in Northern ...
