Walk the parking lot of any commercial property along I-20 and US-67 in Duncanville, and you will see the same story. Cracks running through the concrete, sections that have settled unevenly, spalling along the edges of curbs and sidewalks. Dallas County clay soil expands and contracts with every wet and dry cycle, and that movement lifts and drops slabs over time. Add in the summer heat that pushes surface temperatures past 120 degrees, and concrete takes a beating year after year.
For concrete repair Duncanville TX commercial property owners have trusted since 1981, C & D Commercial Services is the contractor to call. We work on shopping centers near the Duncanville Fieldhouse and nearby Cedar Hill State Park, office buildings, apartment complexes, warehouses, and medical facilities throughout a mature Dallas County suburb with established commercial corridors. Property managers call us when they notice trip hazards forming in sidewalks, when loading dock aprons start cracking, or when parking lot curbs are crumbling apart. Whatever the damage looks like, we have seen it and repaired it before.
Every concrete repair job in Duncanville starts with a walk-through. We meet the property manager on-site, look at every section of damaged concrete, and figure out what is actually causing the problem. A crack in a sidewalk might be from tree roots pushing up from below. A settled slab in a parking lot might be from poor drainage washing away the base material underneath. Until you know the cause, you cannot pick the right repair.
We categorize the damage into three levels. Surface damage — minor spalling, small cracks, worn finish — can often be repaired with resurfacing or crack filling. Structural damage — settled slabs, wide cracks, broken corners — requires removing and replacing the affected sections. Drainage-related damage — concrete failing because water is undermining the base — needs both the concrete repair and a drainage fix to prevent the same problem from coming back.
On commercial properties near the Duncanville Fieldhouse and nearby Cedar Hill State Park and along I-20 and US-67, we see all three types regularly. Dallas County soil conditions make drainage-related damage especially common here. Our assessments always include checking the grade around the concrete to make sure water is moving away from the slab, not pooling underneath it.
Our concrete repair process follows the same steps on every Duncanville job, whether we are fixing a single sidewalk panel or rebuilding a parking lot entrance.
First, we mark out the work area and set up safety barricades. On active commercial properties, this means coordinating with the property manager on traffic flow and pedestrian routing. We never leave an open excavation unattended.
Second, we saw-cut the perimeter of the damaged concrete with a diamond blade. Clean cuts give the new concrete a straight edge to bond against and prevent the surrounding slabs from cracking further.
Third, we remove the old concrete and excavate to the proper depth. For parking lots, that typically means 6 inches of concrete over a compacted base. For sidewalks, 4 inches is standard. If the base material has washed out or degraded, we bring in new crushed limestone and compact it in lifts.
Fourth, we install reinforcement — usually #3 rebar on 24-inch centers or wire mesh, depending on the load requirements. Loading docks and dumpster pads get heavier reinforcement than standard sidewalks.
Fifth, we pour the new concrete, screed it level, apply the appropriate finish — broom finish for sidewalks, trowel finish for interior slabs — and let it cure. We return the next day to strip forms and clean up the site. Most repairs are traffic-ready within 24 to 72 hours depending on weather and concrete mix.
Once we have repaired the concrete on your Duncanville property, the goal is to keep it from failing again. The Dallas County climate is hard on concrete — the summer heat causes thermal expansion, and the clay soil underneath shifts with every rainfall. A few preventative steps go a long way.
Seal your concrete. A good concrete sealer applied every two to three years keeps water out of the surface and slows down the cracking process. This is especially important for parking lots along I-20 and US-67 where vehicles track in oils and chemicals that degrade the surface over time.
Keep expansion joints clean and sealed. When joints fill with debris and then water, that water works its way under the slab and erodes the base. We see this pattern constantly on properties near the Duncanville Fieldhouse and nearby Cedar Hill State Park — a failed joint leads to a settled slab leads to a full repair.
Watch the drainage. If water is pooling against a curb or running under a sidewalk after rain, that is a problem that will get worse. Small drainage fixes — regrading a swale, extending a downspout — cost a fraction of what a concrete replacement costs.
We offer annual inspections for Duncanville commercial properties. We walk the site, document any new cracking or settlement, and flag issues before they turn into trip hazards. Most property managers find that catching problems early keeps their concrete repair budget predictable.
We do not list prices on a website because every concrete repair is different. The extent of damage, the type of concrete, whether the issue is surface-level or structural, whether we need to address drainage or base issues underneath. What we can tell you is that we have been buying concrete and repair materials from the same DFW suppliers for over 40 years. Those relationships mean our material costs are lower than most competitors, and we pass that along. Property managers who compare our quotes typically find we come in lower.

How long should a concrete repair last?
A properly done concrete replacement should last 20 to 30 years. The key word is properly — if the base is compacted, the reinforcement is adequate, and the drainage is addressed, the new concrete will hold up. We have repairs we did 20 years ago on Duncanville properties that are still in good shape. Repairs done without fixing the underlying cause will fail much sooner.
What is the difference between concrete resurfacing and replacement?
Resurfacing applies a thin layer of new material over existing concrete that is structurally sound but cosmetically worn. It is good for surface spalling and minor cracking. Replacement means removing the old concrete entirely and pouring new. If the slab has settled, is structurally cracked, or has base failure underneath, resurfacing will not hold — you need replacement. We tell you which one applies after seeing the damage.
Do you handle sidewalk and ADA ramp repairs?
Yes. We repair and replace sidewalks and ADA ramps throughout Duncanville. This includes replacing tripped sidewalk panels, rebuilding curb ramps to current ADA slope requirements, and installing detectable warning surfaces. ADA compliance is something we take seriously — if a sidewalk or ramp on your property does not meet current standards, we can bring it up to code as part of the repair.
Can you fix sunken or uneven concrete slabs?
Yes. For slabs that have settled, we can either replace them outright or use mud jacking — pumping a grout mixture under the slab to lift it back to grade. Mud jacking works well for slabs that are structurally intact but have dropped. If the slab is also cracked, replacement is usually the better call. We evaluate each situation and recommend the method that will hold up long-term.
What happens if I ignore cracked concrete on my property?
It gets worse, and it gets more expensive. A crack lets water under the slab, which erodes the base, which causes more settlement and more cracking. A trip hazard that is half an inch today can be two inches next year. And if someone trips and gets injured, you are looking at a liability claim that costs far more than the repair would have. Addressing concrete damage early is always cheaper.
