Commercial slab repair covers structural concrete that has settled, cracked, or dropped under load, loading dock aprons, retail entryways, warehouse floor sections, and parking structure decks. Unlike a homeowner's driveway, commercial slabs carry forklift traffic, racking loads, and daily foot traffic, so a repair has to hold under repeated stress, not just look flat.
McKinney's rapid commercial growth means a lot of this flatwork sits on the same recently graded fill soil as the residential subdivisions around it, and it settles the same way.
What's included
What's Included with Commercial Slab Repair
Typically included: site assessment for load type and traffic, foam injection to fill the void and lift the slab, hole patching with a traffic-rated compound, and a post-lift level check.
Optional: joint resealing along expansion joints, soil stabilization injection for repeat-settlement areas, coordination around facility operating hours.
Customer prep: clear the work area of racking, pallets, or parked vehicles, and flag any underground utilities or conduit runs near the repair zone.

How Our Commercial Slab Repair Process Works
Step 1Site walkthrough
Assess slab condition, traffic type, and settlement pattern.
Step 2Load planning
Match foam density and injection pattern to expected traffic.
Step 3Marking injection points
Lay out drill locations around the settled area.
Step 4Drilling access holes
Small diameter holes placed for minimal disruption.
Step 5Foam injection
Expanding foam fills the void and lifts the slab section.
Step 6Lift monitoring
Track elevation with a laser level during injection.
Step 7Hole patching
Seal access points with a traffic-rated patch compound.
Step 8Final walkthrough
Confirm the slab is level and ready for full load.
Materials
Materials and Methods for Commercial Slab Repair
Commercial slabs need materials rated for continuous heavy loads, not just foot traffic, and McKinney's clay soil movement means the fix has to hold through wet and dry cycles without softening.
High-density structural polyurethane foam
rated for warehouse and loading dock loads, this foam expands to fill voids under thick commercial slabs without compressing under forklift or rack weight.
Traffic-rated patch compound
seals injection holes with a surface that matches the load rating of the surrounding slab, so patched spots don't become the next weak point.
Soil stabilization resin
injected into loose or fill soil beneath repeat-settlement zones to reduce future movement, especially useful on newer commercial pads built on graded ground.

DIY vs Hiring a Pro for Commercial Slab Repair
| DIY | Hire a pro |
|---|---|
| Surface patch products can fill small cracks temporarily | Injection equipment lifts the full settled section evenly under load conditions |
| Fine for cosmetic touch-ups on low-traffic areas | Foam density matched to actual traffic and load requirements |
| Doesn't address the soil void causing the settlement | Written estimate covers scope before any drilling starts |
| Risk of the repair failing under forklift or rack loads within months | Work scheduled around facility operating hours to limit downtime |

FAQs
Commercial Slab Repair FAQs
How much does commercial slab repair cost?
Cost depends on slab thickness, load rating, and the size of the settled area. Most jobs range from a few hundred dollars for a small dock apron section up to several thousand for a large warehouse floor repair. A site visit gives an accurate number.
Can commercial slab repair be done without closing the building?
Most foam injection jobs can be scheduled around business hours or during a slower shift, and the area is usually back in service the same day.
Is foam injection strong enough for forklift traffic?
High-density structural foam is rated for the same loads as the original slab when matched correctly to the traffic type.
How long does a commercial slab repair last?
A properly injected repair typically lasts as long as the surrounding slab, since it fills the void causing the settlement rather than just patching the surface.
Does insurance cover commercial slab repair?
Coverage depends on the cause and your policy. Settlement from soil movement is often not covered, but repair from a specific covered event might be. Check with your provider.
Do I need a structural engineer to sign off on the repair?
For most void-fill and lift jobs, no. If the repair involves foundation-connected structural elements, an engineer review may be recommended before work starts.
