What does spalling concrete look like?
Spalling concrete can look like round or oval depressions along surfaces or joints. Spalling tends to be most common in cold climates when de-icing chemicals are applied or when seasonal freeze-thaw cycles damage the concrete.
Does salt deteriorate concrete?
The answer is yes, salt does indirectly damage your concrete driveways, patios and sidewalks. Bumps and potholes don’t just appear due to regular wear and tear – salt damages concrete over time by causing corrosion to occur under the surface, leading to discolored, cracked and crumbling concrete.

Is concrete spalling dangerous?
Concrete spalling is more common in colder climates, where the concrete endures freeze-thaw cycles. Because spalling can be a sign of deep, dangerous damage that can result in further issues, it’s important to repair spalling at the first sign of brokenness or flaking.
What causes concrete flaking?
When the temperature drops below freezing, moisture in the concrete tends to expand, creating internal pressure. Over the course of a winter, or over the course of years, as the internal pressure rises and falls, it stresses the surface layer of the concrete, which leads to spalling.
