Signs Your Concrete Surface Is Breaking Down
Concrete pitting and flaking often begin with subtle surface changes that worsen over time. Look for a rough, pockmarked finish, small chips that expose the aggregate below or areas where the top layer begins to peel away (concrete spalling). Damage often appears first along slab edges, steps and other areas exposed to moisture and de-icing salts. If your concrete feels rough underfoot where it used to feel smooth, the surface layer has likely started to fail.
Causes
What Causes Concrete Pitting, Flaking & Spalling?
Concrete surface damage doesn't usually happen overnight. Concrete pitting typically starts as small holes or shallow dips in the surface. As the deterioration progresses, the surface may begin flaking, and in more advanced cases, concrete spalling can occur as larger pieces break away. Much of this damage comes from years of exposure to moisture, freeze-thaw cycles, de-icing salts and everyday wear. Identifying the cause of the deterioration helps determine whether the concrete can be protected or if more extensive repairs are needed.
How Concrete Pitting & Flaking Happens Over Time

Stage 1
Healthy Concrete Surface
Concrete begins life with a dense, smooth surface built to resist moisture and everyday wear. When it’s properly protected, it can hold up to years of exposure to weather, traffic, and seasonal changes.

Stage 2
Moisture & Weather Break It Down
Eventually, water, de-icing salts, UV exposure and freeze-thaw cycles begin wearing down the concrete surface. As moisture soaks into the slab, repeated freezing and thawing weaken the top layer and accelerate surface deterioration.

Stage 3
Visible Pitting, Flaking & Spalling
As the surface deteriorates, small pits, chips and flakes start to appear. Left untreated, the damage continues to spread, exposing more concrete to moisture and speeding up deterioration. SealantPro® helps shield concrete from additional moisture intrusion, slowing future surface deterioration and extending the life of the slab.
