Concrete Cracks to Watch For This Summer in Atlanta

As temperatures rise, concrete cracks in Atlanta become more common. The region’s extreme summer heat and expansive clay soil can wreak havoc on driveways, patios, and foundations. Atlanta’s soil shrinks during dry spells and expands after heavy rains — this natural push-and-pull puts added stress on concrete surfaces.

But here’s the good news: Most summer concrete issues in Atlanta are common and completely fixable with expert concrete repair when caught early. Here’s what to look out for.

Atlanta’s clay-rich soil is highly reactive. In summer, it dries out and shrinks. When rain returns, it swells. This constant movement causes concrete cracking from heat Atlanta as slabs shift unevenly.

Long stretches of dry weather shrink the soil underneath your concrete. As the support weakens, slabs can sink or crack — leading to those serious summer concrete cracks Atlanta neighborhoods know all too well.

Without proper grading or compacted soil, water can wash away the ground beneath slabs. That void creates instability, increasing the risk of developing unsightly concrete cracks Atlanta homeowners dread.

Roots can push up from below, while poorly poured concrete might not hold up under Atlanta’s summer extremes. Both scenarios lead to surface stress and cracking, especially on sidewalks or other surfaces near trees.

• Driveways & Sidewalks: High traffic and exposure to the sun make them prime targets.
• Patios, Porches, and Pool Decks: Cracking here is often worsened by heat and water exposure.
• Basements and Garage Floors: Can show signs of foundation issues.
• Foundation Slab: Cracks here may signal deeper structural problems.

• Walk your property and inspect all concrete surfaces
• Look closely after long dry spells or major rainstorms
• Use a level or tape measure to spot sinking or shifting areas
• Check to see if existing cracks have expanded
• Notify experts if cracks worsen

Polyurethane Foam Injections

Polyurethane foam injections are the most advanced and effective solution for lifting and stabilizing sunken concrete in Atlanta. This modern method involves injecting lightweight, high-density foam beneath the slab, which expands to fill voids and raise the concrete quickly and precisely. It’s clean, fast-curing, and minimally invasive.

Mudjacking

Mudjacking is an older method that uses a cement-based slurry to lift sunken slabs. While it can provide temporary results, it’s less precise than polyurethane foam and much heavier, which can add stress to already unstable soil. The process also requires larger holes to be drilled into your concrete and typically takes longer to cure.

Concrete Replacement

Concrete replacement may be necessary when slabs are beyond repair. While this approach delivers a fresh start, it’s the most expensive and disruptive option. Full replacement requires demolition, curing time, and a larger investment of both time and money. For most cases of concrete cracking from heat in Atlanta, poly injections are a superior solution.
