Concrete Expert Matt Wallace Explains What to Know Before Repairing Concrete in HelloNation

The article explains why understanding the cause of concrete damage leads to more effective and longer-lasting repairs.

MADISON, Wis., Oct. 2, 2026 /PRNewswire/ -- What causes concrete cracks? A HelloNation article featuring insights from Concrete Expert Matt Wallace of The Concrete Company in Madison, Wisconsin, explains why identifying the source of damage is one of the most important steps before beginning any concrete repair.

The article explains that visible damage is not always the full story. A crack in a driveway or patio may appear to be a simple repair, but the underlying cause often determines whether the repair will last. Addressing only the surface without correcting the conditions beneath it can allow the same problem to return.

According to the article, concrete can crack for many different reasons. Normal settling, freeze and thaw cycles, heavy vehicle traffic, poor drainage, tree roots, and unstable soil can all contribute to damaged concrete. Because every situation is different, the article explains that the appropriate concrete repair depends on understanding what caused the damage in the first place.

The article notes that smaller imperfections such as shallow cracks, minor chips, and light surface wear are often good candidates for repair when the concrete beneath remains stable. Cosmetic repairs can improve appearance while helping reduce moisture intrusion. However, even small cracks deserve careful evaluation if they continue to grow or appear in several locations, as they may indicate a larger issue.

Larger cracks often require a more detailed assessment. The article explains that movement below the surface may be responsible when sections of a driveway or patio have settled or shifted. Simply filling the visible crack will not prevent additional movement if poor soil conditions, an unstable base, or water beneath the slab continue affecting the concrete. Understanding the condition of the foundation is just as important as evaluating the surface itself.

Drainage is another important factor discussed in the article. Water that repeatedly collects around concrete surfaces can gradually weaken the supporting soil and contribute to uneven settling. The article explains that correcting drainage problems before completing a concrete repair can improve long-term performance and reduce the likelihood of future damage. Without addressing drainage, the conditions that caused the original cracks may remain.

The article also explains that the age of the concrete should influence the decision between repair and replacement. A newer slab with isolated damage may respond well to professional repair when the surrounding concrete remains structurally sound. Older surfaces with widespread cracks, repeated repairs, or significant settlement may have reached the point where replacement provides a more dependable long-term solution.

Daily use also plays a role in selecting the right approach. According to the article, a patio that primarily supports outdoor seating experiences different stresses than a driveway that carries multiple vehicles every day. Considering how the surface is used helps determine whether a repair is likely to provide lasting performance or whether additional structural work may be necessary.

The article concludes that successful concrete repair depends on looking beyond the visible damage. Evaluating damaged concrete by considering cracks, drainage, soil conditions, age, and daily use helps homeowners make more informed decisions. Understanding the cause of the problem before beginning repairs increases the likelihood of achieving a durable result instead of a temporary fix.
