Concrete plays a major role in the safety, function, and beauty of homes and businesses throughout Raleigh, NC. From residential driveways and patios to commercial walkways and foundations, concrete structures must withstand years of use and exposure to the elements. But even the toughest concrete wears out—and the key to saving money is catching the warning signs early.
At Legendary Concrete – Raleigh, NC, we specialize in helping property owners identify when their concrete surfaces need professional attention. Here are the top five signs your concrete may need repair—or a full replacement.
1. Cracks That Keep Growing
Hairline cracks are common, but if the cracks in your concrete are widening, deepening, or forming branching patterns, it could point to a serious issue. These larger cracks are often caused by soil movement, erosion, or pressure from moisture beneath the surface. In Raleigh, the changing seasons and rainfall can cause shifts that lead to cracking. Depending on the extent, cracks can sometimes be filled and sealed—but if they’re structural or widespread, replacing the slab may be necessary.
2. Uneven or Sunken Surfaces
Have you noticed your sidewalk, patio, or driveway looking uneven or lopsided? Concrete that sinks in one area while remaining elevated in another is often a result of poor subgrade support or soil erosion. In some cases, water can wash away the soil beneath the slab. These uneven surfaces not only affect appearance but also create safety hazards. Some sunken areas can be lifted with slab jacking, but large or unstable sections often require complete removal and repouring.
3. Surface Deterioration: Flaking or Spalling
Raleigh’s freeze-thaw cycles and high humidity levels can damage the top layer of concrete. When water seeps into the surface and freezes, it expands and causes the outer layer to flake off—a condition known as spalling. This weakens the concrete and opens the door for further deterioration. If the issue is caught early, resurfacing might be enough. But if the damage extends deeper, replacing the slab will be the better long-term solution.
4. Standing Water After Rain
If water pools on your concrete surface after a rainfall, it’s more than just a drainage concern. Pooling water often indicates that the slab is uneven or has developed low points due to settling or erosion. Left unaddressed, this moisture can penetrate the concrete, leading to cracking, mold growth, or base failure. In a climate like Raleigh’s—where heavy storms are common—proper grading is essential. Poor drainage may require slab replacement to restore correct slope and function.
5. Rust Stains or Exposed Rebar
If you spot rust stains bleeding through the surface of your concrete—or worse, see actual metal rebar showing—it means water has reached the steel reinforcement inside. As the steel corrodes, it expands, placing pressure on the surrounding concrete and causing cracks or surface bulging. This is a clear sign that the slab’s internal integrity has been compromised. In nearly all cases, this kind of damage calls for a full concrete replacement.
