What causes concrete to flake off?

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.

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.

How do you stop concrete spalling?

What is spalling damage?

Spalling is the result of surface or sub-surface fatigue, which causes fractures to form in the running surfaces. When the rolling elements travel over these cracks, pieces, or flakes, of material break away. (Spalling is also referred to as “flaking,” “peeling,” or “pitting.”)

Do concrete overlays last?

Concrete overlays are only as good as the surface, it is being applied to. You need to keep in mind that if the concrete is cracked or surfacing up, then the overlay will also break and come up. You need to be sure that if the concrete is heavily damaged, your overlay won’t last long.

Is concrete spalling dangerous?

Spalling is a result of water ingress that reaches into the structures of buildings causing surface peeling or flaking due to moisture in the concrete. … Underestimating the damage resulting from spalling is dangerous. If ignored, it may lead to larger more costly repairs and even building condemnation.

Can you pour concrete over stamped concrete?
