Causes of Concrete Damage

Your concrete driveway, sidewalk, pool deck, and patio can sustain damage for many reasons. Learn what's behind it and what you can do to fix it.


Cracking, crumbling, and heaving concrete around your North Carolina home may seem like it came out of nowhere. While it certainly can feel this way, there are many elements at work that will cause your concrete to be damaged over time. Here, we’ll explore what is behind your concrete problems.

Common Causes of Concrete Damage  

soil washout and erosion


On average, North Carolina experiences 48 inches of rain per year, which is above the national average of 38 inches. An abundance of rain in any context can be detrimental to your concrete, as it can cause flaking and spalling, and of course, erode the soil supporting the concrete, too.  As the soil washes out, air pockets begin to form beneath your concrete. Since it is now lacking the support of the soil underneath, you may notice it collapsing or cracking over time and crumbling inward.  

shrinking soil


North Carolina also experiences periods of drought, which can exasperate cracking not only in your concrete sidewalks and driveways but your foundation as well. Drought tends to increase bush and tree root activity, as the roots in your yard will extend further and wider in search of water. This has caused concrete cracking as roots grow underneath concrete slabs, causing them to crack or lift.

Poor Installation

If contractors install your concrete poorly or on a bad weather day, your concrete damage will not work itself out over time. Too much water in a concrete mixture or even poor materials will render your concrete weaker and more susceptible to damage by the elements. Poor installation, like not tamping down the concrete enough or buckling interior concrete supports, can cause honeycombing or delamination to your concrete. Worst-case scenario, you may have to completely remove and re-lay the concrete. 

Tar Heel Basement Systems Is Your Concrete Expert 

Mudjacking as a traditional concrete repair method may be able to temporarily fix your damaged concrete, but it’s a messy and labor-intensive process that does not address the root cause of the problem. Polyurethane foam injections are more reliable solutions that not only lift your concrete but cure in just 15 minutes. Since the foam is so light, over time it won’t weigh down your concrete like mudjacking or even a full concrete replacement.
