Concrete is strong, but it is not perfect. Over time, weather, water, and daily use can cause damage. The good news is that many problems can be fixed if you catch them early. Knowing the difference between cracks, spalling, and settling can help you determine the best course of action—and when replacement becomes more sensible.
Cracks: Small vs. Serious
Cracks are one of the most common concrete problems. Some cracks are small and happen as the concrete cures and shrinks. These cracks are often thin and do not change much over time. Other cracks can be wider, longer, or keep growing. These may point to movement under the slab, water problems, or heavy loads.
A simple way to judge a crack is to watch if it spreads, gets wider, or creates uneven edges. If a crack lets water in, it can lead to more damage, especially during freeze-and-thaw cycles or after heavy rain. Sealing or patching early can help stop the crack from getting worse.
Spalling: Flaking and Surface Damage
Spalling is when the top layer of concrete starts to chip, flake, or peel. It often looks like rough spots or missing pieces on the surface. Spalling can happen when water gets into the concrete, from de-icing salts, from poor finishing, or from normal wear.
Small spalling areas can sometimes be repaired with surface patch products or resurfacing. But if the spalling is deep or spread out, the concrete may be weaker than it looks and may need a more serious repair.
Settling: When Concrete Sinks or Drops
Settling happens when the soil under the concrete shifts or washes out. This can cause slabs to sink, tilt, or become uneven. You may notice a trip hazard on a sidewalk, a driveway that dips, or gaps between the slab and nearby structures.
Settling is not just a surface issue. It often means the base under the concrete is no longer stable. Repairs may include leveling methods and fixing drainage issues so the problem does not come back.
When to Repair and When to Replace
Concrete repair is usually the best choice when damage is small, stable, and limited to a few areas. Replacement may be better when the slab is badly broken, sinking in many spots, or has serious damage that keeps returning. If safety is a concern—like a major trip hazard—replacement can also be the smarter long-term choice.
