When the ground beneath your driveway moves like that, the concrete above can't simply bend and flex to accommodate it. Instead, it cracks. It settles unevenly. Sometimes entire sections heave upward or sink down, creating those frustrating lips where your garage meets your driveway or where sections suddenly sit two inches higher than their neighbors.
Heat, UV, and Temperature Swings Beat Down From Above
While soil movement attacks from below, Dallas's climate hammers your driveway from above.
Summer high temperatures range from 94 to 98°F, and often push into triple digits. That sustained heat and UV-exposure accelerates surface deterioration and puts stress on control joints and edges where your driveway meets landscaping, sidewalks, or garage floors.
The UV index during these months averages 10, which steadily degrades sealers and surface treatments. Once those protective layers break down, moisture can infiltrate surface cracks more easily.
Then winter arrives with average lows around 39.9°F, a temperature swing of more than 55 degrees between seasonal extremes. When water that's seeped into those tiny cracks freezes, it expands. That's when you get spalling, that pitted, gravelly-looking surface deterioration that makes older driveways look like they're slowly disintegrating.
This is why properly mixed concrete for Dallas should include air-entrainment admixtures, which create microscopic air bubbles throughout the concrete that give freezing water room to expand without damaging the surface.
Add Dallas's 38.32 inches of annual rainfall to this equation, and you've got water constantly probing for weaknesses, finding cracks, and exploiting them during temperature swings.
This combination—expansive clay below, extreme thermal cycling above—means replacing a driveway in Dallas requires specific expertise. Standard installation methods that work fine in moderate climates with stable soils will fail here within a few years.
Is Your Driveway Telling You It's Time?
Given the forces working against concrete in Dallas, driveways here typically show their age faster than in gentler climates. While a properly installed driveway in moderate conditions might last 30 to 40 years, Dallas driveways often hit their limit sooner, particularly if the original installation didn't account for soil movement or thermal stress.
Watch for these signs that replacement can't wait:
- Alligator Cracking: You'll see multiple cracks intersecting to form alligator-skin patterns across your driveway. This appears after countless wet-dry soil cycles that stress the concrete above. Once you see this, the entire slab needs replacement.
- Settling and Heaving: Sections sitting more than an inch or two higher or lower than adjacent areas signal serious soil movement. This changes drainage patterns, creates trip hazards, is bad for your car and accelerates further cracking.
- Spalling: Surface pockmarks where concrete has popped out, exposing aggregate underneath. Once spalling affects more than 20 to 30 percent of your driveway, you need replacement rather than repair.
- Major Structural Cracks: Cracks wider than a quarter-inch indicate structural failure. These often appear near downspout discharge points, property lines, or mature trees where moisture levels vary or roots have grown under the slab.
- Standing Water: When sections settle unevenly, the designed slope (typically 1/8 inch per foot) disappears. Pooling water accelerates deterioration and may triggering more movement.

The Questions That Separate Experts From Amateurs
Any contractor can pour concrete. Not every contractor understands how to make it survive Dallas's unique challenges. These questions will reveal who actually knows what they're doing.
Soil Stabilization: Do They Even Recognize the Problem?
Ask directly: "How do you address expansive clay soils in your installation process?"
Listen carefully to the answer. You're looking for specific acknowledgment of the clay soil issue and concrete methods to address it. They should talk about proper base preparation with compacted aggregate, adequate slab thickness and reinforcement, or in severe cases, excavation and replacement with more stable fill material. Make sure they recognize expansive clay as a problem that requires special prep.

Thickness and Reinforcement: Are They Building for Your Conditions?
Standard driveway thickness might be four inches. On expansive soils in Dallas, that's not enough.
Ask: "What thickness and reinforcement do you recommend for my driveway, and why?"
The answer should reference at least five to six inches of thickness with steel reinforcement or fiber mesh throughout. But more important than the numbers is whether the contractor can explain why those specifications matter for your specific property—considering your drainage patterns, proximity to irrigation systems, and nearby trees.
Control Joints: Channeling the Inevitable Cracks
Concrete will crack. That's not a defect—it's the nature of the material. Control joints let you decide where those cracks happen.
Ask: "How will you handle control joints, and where will you place them?"
Proper spacing, typically every eight to ten feet in both directions, creates panels as square as possible. This allows the concrete to crack at the joints rather than randomly across the slab face. The contractor should explain how they'll position joints to accommodate soil movement patterns specific to your property.
Poor joint planning means cracks wandering across the middle of your driveway instead of hiding at the joints where they belong.
Understanding Your Driveway's Failure: What Went Wrong?
Your current driveway failed for specific reasons. A good contractor treats that failure as a diagnostic opportunity.
Ask: "Will you inspect my existing driveway to determine why it failed?"
The contractor should examine the failure pattern, including where cracks appeared, which sections settled, how water drains. This tells them whether the problem was inadequate thickness, poor base preparation, missing reinforcement, or soil issues that weren't addressed in the original installation.
A contractor who just says "we'll tear it out and pour a new one" is likely to repeat the same mistakes. One who studies what went wrong can design the replacement to avoid those specific failures.
For properties with severe or unusual damage patterns, reputable contractors may recommend geotechnical testing or soil boring to understand exactly what's happening beneath the surface before committing to a solution.

Mix Design and Curing: The Technical Details That Determine Longevity
Dallas's heat changes how concrete needs to be mixed and cured. This is where technical knowledge separates professionals from general laborers.
Ask: "What concrete mix design do you use, and how do you handle curing in Dallas's summer heat?"
You should hear specifics: minimum 3,500 to 4,000 psi strength, appropriate water-cement ratio, and detailed curing methods that prevent rapid moisture loss during hot weather. Some contractors use curing compounds, others use wet curing with water or wet burlap, and some apply specialized techniques for extreme heat.
What matters is that the contractor recognizes Dallas's heat affects curing and has a specific plan to address it. Concrete that cures too quickly won't reach its full strength and won't hold up to thermal cycling over the years.
Permits and Credentials: The Boring Stuff That Protects You
Dallas requires permits for driveway work that affects the right-of-way. That’s the section between your property line and the street.
Ask: "Do you handle all necessary permits, and can you provide proof of licensing and insurance?"
The contractor should know Dallas's permitting requirements and be willing to pull permits through the city's system. They should carry liability insurance and workers' compensation coverage. Ask to see current certificates.
Working without required permits creates headaches later, particularly when you sell your home and unpermitted work must be disclosed or corrected.
Warranties: What's Actually Covered?
Given Dallas's challenging conditions, understanding warranty terms matters more than just knowing the warranty exists.
Ask: "What warranty do you offer, and specifically what does it cover and exclude?"
Reputable contractors typically offer three to five years of warranty coverage. But the details matter. Most warranties exclude damage from soil movement beyond reasonable engineering standards. That means if your entire neighborhood is built on the same clay that shifts dramatically, that may not be covered.
Understanding these limits upfront prevents disputes later and gives you realistic expectations for what the contractor stands behind.
