Cracked Concrete

Are you noticing cracks along your driveway, sidewalk, and other concrete structures? These fissures can vary in size and cause, but we’ll let you know what’s behind them, what to look for, and how we can help.

Schedule Free Inspection

Have you ever seen a driveway with small fractures running up and down the concrete in various sections? Perhaps you’ve seen a sidewalk with massive gaps and collapsing concrete portions. Whether the fissures are huge or microscopic, they indicate a problem with the concrete. Here, we’ll go over all you need to know about cracked concrete.

Different Types of Concrete Cracks

Different types of cracks mean different things and can form from various sources, most notably the soil underneath concrete slabs. First, you must distinguish between concrete fractures that are actually threatening to your property and those that are simply evidence of earlier problems. 

Hairline Crack

Static, Hairline Cracks

Static cracks are ones that have already formed and stabilized. The majority of these are caused by a property’s natural settling process after construction, including concrete. This is not to be confused with foundation settlement, which is another type of foundation deterioration. Static cracks are no longer expanding and, unless they are extremely large or deep, represent no threat to the general structure of your home or concrete. The majority of static cracks generated by settling are hairline cracks, meaning they are small enough to fit a credit card through.

Active, Spreading Cracks

Active or spreading cracks, on the other hand, are cracks that are still forming. These are a symptom of active and ongoing pressure in a property, and their location, direction, and depth can aid in the diagnosis of difficulties. For example, these cracks can be accompanied by unevenness, especially in sidewalks, driveways, and other areas with a series of concrete slabs.

Deep Cracks and Gaps

Deep cracks and gaps in concrete slabs are similar to active, spreading cracks, but these appear to cut right through concrete. They, too, are accompanied by significant movement and unevenness, and are typically the result of shifting and unstable underlying soil. The type of soil varies throughout South Carolina and Georgia, ranging from sandy to expansive clay, and it often has problems with movement and stability. 


Small, hairline cracks are normal after cement has been poured to form concrete slabs. They usually show up during the concrete curing process or as the slabs settle into their positions in the ground, and they will not grow or change in size or appearance. Growing, deep cracks, however, are a bigger problem indicating issues with the underlying soil or the concrete when it was mixed and poured. 

Sometimes, there is a problem with the concrete mix, and other times nearby roots from trees and plants can be the culprit. Typically, the root cause of concrete cracks has to do with the soil underneath and around the concrete slabs. Excess precipitation can lead to soil washout and erosion during which soil particles are washed away and the soil’s structural integrity deteriorates. Soil also can shrink and dry out when there is a lack of moisture, as well as suffer from poor compaction. In all of these cases, soil that cannot properly support concrete can lead to the slabs sinking into the ground and cracking. 

Unfortunately, DIY cracked concrete repairs are not advised. Simply caulking over a crack may only cover up the cosmetic aspect and the problem can still occur and grow worse. Other installations may require the need for specialized tools. The best way to address cracking concrete is to contact local repair professionals for a free estimate. They will be able to get to the bottom of your concrete woes, recommend customized repairs, and install a state-of-the-art solution to lift, stabilize, and protect your concrete.
