Commercial Concrete Contractor
Commercial work around the lake has its own rhythm — restaurant and retail projects near Birkdale Village and the Exit 28 corridor in Cornelius, marina and club amenities on the water, office space along the I-77 exits. We self-perform site concrete and flatwork for those projects: walks and plaza space, dumpster pads, aprons, curb, ADA routes, and interior slabs. Crews pour to the engineer's drawings, keep the GC's schedule, and turn over closeout documentation without being chased. We hold the insurance coverage commercial contracts require, and our pricing comes from the plans fast enough to help your bid, not delay it.

A commercial pour is not a residential pour scaled up. The mix design is different, the thickness is different, the reinforcement layout is different, and the pour window is almost always different. A retail slab taking pallet-jack traffic and box-truck deliveries needs 4000 to 5000 PSI concrete on a compacted stone base, six to eight inches thick, with a rebar grid or dowel-bar detail that most residential shops never write. Cut those numbers and the slab starts map-cracking inside the first three years — a problem that surfaces long after final payment.
Local Concrete Charlotte handles commercial concrete across the Charlotte metro and the surrounding Piedmont — new pours, tear-out and replacements, and additions for retail, medical, restaurant, office, and light-industrial buildings from Airport West through Northlake, Steele Creek, University City, and out to the Concord Mills submarket. Every commercial job begins the same way a residential one does: a walk covering subgrade, drainage, existing tie-ins, and how the space is actually going to get used day to day. The walk becomes a written spec — mix design, slab thickness, joint layout, reinforcement, pour sequence, cure plan. Nothing owed up front — the invoice goes out after the pour is placed, walked, and signed off. The certificate of insurance lands on the property manager or GC's desk before we set the first form.
Our Commercial Concrete Services
Commercial concrete covers a wide range of work, and each variation shifts the spec on mix, thickness, joints, and how the pour has to be scheduled around a live building.
- Retail floor slabs and storefront interiors, tenant-improvement fit-outs included
- Medical office pads, entry ramp pours, and ADA-conforming walk paths
- Restaurant back-of-house floors, dishwashing areas, and kitchen service slabs
- Entry aprons at storefronts and transition sections tying into public sidewalk
- Walk pours fronting commercial properties, right-of-way work included
- Light-industrial floor pours for shops, warehouse bays, and service garages
- Truck-approach aprons, dumpster corrals, and dock-level pads
- Interior slab-on-grade with FF/FL flatness targets under racking or shelving systems
- Curb ramps, stoops, and outdoor stair landings at commercial doorways
- Tear-out and repour around existing buildings with no disruption to buried utilities
Commercial work often has to happen after hours or on weekends so a tenant can stay open through the pour. Tenant-improvement jobs across Airport West and TI-heavy office parks in University City routinely fall into this bucket. We work to the building's operating hours, coordinate staging with the GC or property manager, and phase the pour so half the parking lot or half the entryway remains usable while the fresh side cures.
What Makes Concrete Commercial
Commercial concrete separates from residential in five specific places on the spec sheet, and each one is driven by the load on the slab and the occupancy code the building has to satisfy.
- Mix — commercial pours generally call for 4000 to 5000 PSI where residential runs 3000 to 3500 PSI, because both wheel loads and cycle counts run higher
- Depth — six to eight inches on most commercial slabs where a residential drive runs four, with thickening at load bearing points and turnaround aprons
- Steel — a proper rebar grid (#4 or #5 bar at 12 to 18 inch spacing) or dowels transferring load across construction joints, versus fiber or mesh on residential
- Sawed joint pattern — control joints cut on tighter spacing (roughly 12 to 15 feet on center for a six-inch pour) with sealant filling every one
- Documentation — a certificate of insurance listing the property owner and GC as additional insured, contractor licensing paperwork, and often a full submittal package before mobilization
Commercial pours also carry a different liability picture. A slab failure at a retail entrance in Northlake or Concord Mills is a trip-and-fall claim; a failure at a medical building off Randolph or Providence is a worse conversation. That is the reason mix, thickness, and reinforcement all move up from residential baselines — the slab has to take more traffic, over more years, with less room for surface defects the tenant's customers will notice.

Spec Details: Mix, Reinforcement, and Joints
The written spec on a commercial pour lays out exactly what is going under the surface. Any commercial contractor worth working with should hand you these numbers before pour day, and every line represents a cost driver you can ask questions about.
- Mix — 4000 PSI is the working baseline for parking areas and walkways, 4500 to 5000 PSI on dock zones and heavy-truck lanes, and air-entrained at 5 to 7 percent for the freeze-thaw environment across the NC Piedmont
- Slab depth — 6 inches under passenger vehicles and light foot use, 7 inches under delivery vans and light trucks, 8 inches or greater under loaded semis, dumpster staging areas, or transformer pads
- Sub-base — 4 to 6 inches of ABC crusher-run compacted over a proof-rolled subgrade, with geotextile added where native ground is heavy Piedmont clay
- Steel — #4 bar at 18-inch spacing forms the standard grid; #5 at 12-inch spacing under truck approaches; dowel bars carrying load across construction joints
- Control joint layout — cut to a depth of one-quarter the slab thickness, spaced at roughly 24 times that thickness (a 6-inch pour therefore gets joints every 12 to 15 feet)
- Sealant — semi-rigid polyurea inside forklift-active floors, standard exterior sealant outside, refreshed on a 5 to 8 year cycle
- Curing — a wet cure or curing compound applied over the first 3 to 7 days, and a return-to-service schedule spelled out in the spec
None of this gets buried inside the quote. The mix ticket comes back to you after the pour and the joint plan is drawn on the site plan before pour day.
When to Replace, Not Repair
A commercial slab telegraphs its failure well before it goes. When several of the signs below stack up on the same slab, patching stops being economical and starts costing more than the replacement pour it is putting off.
- Broad map cracking or spider-web patterns across the field of the pour — indicates base failure or an under-spec mix, not a single localized problem
- Panels heaved or dropped out of plane by more than half an inch — trip-and-fall risk at a commercial entry sits in a different liability category than a residential driveway
- Surface spalling that has punched through the paste and revealed rebar or mesh — chlorides are now reaching the steel and the slab's clock has started
- Joint edges breaking down under wheel loads from forklifts or trucks — replacing sealant alone will not restore an edge that has lost its concrete
- Loading dock or apron pours that have pulled away from the main slab and dropped at the truck lane — a very common failure signature indicating base loss
- Water pooling in low areas of a slab that used to shed cleanly — the subgrade has moved and the pour has moved with it
- Cracks tracking the same pattern across every panel — the original joint layout was mismatched to the mix and thickness, and patching cannot rewrite that
Once two or three of these are showing on a slab past twenty years old, the replacement number almost always wins on ten-year math. We write both quotes — patch and replace — and set them next to each other so the owner or property manager can make the call on real figures.
Why Business Owners and Property Managers Work With Us
Local Concrete Charlotte runs residential and light commercial concrete across Mecklenburg, Union, Cabarrus, Gaston, and neighboring counties. A commercial job carries more coordination and more paperwork than a residential drive, and both get handled up front so the owner or PM is not chasing anything.
Here is how that shows up on your slab:
- No money down — billing comes after the pour is placed, cured to its return-to-service milestone, and walked with you or the GC
- Complimentary on-site estimates including the written spec: mix, thickness, steel, joint plan, cure schedule, and pour window
- Fully licensed with insurance — COI listing property owner and GC as additional insured, delivered before the first form is set (a required commercial item, not optional)
- Direct coordination with the GC, PM, or building operations team on pour timing so the tenant keeps operating
- Off-hours and weekend pours available for occupied premises, with return-to-service milestones committed to the schedule
- Actual jobsite photos from prior commercial pours across the metro — retail, medical, restaurant, light industrial — never stock imagery
- Honest breakdowns on what moves the price — slab depth, steel class, sub-base condition, demolition difficulty, pour window, and phased pour count — so the total is fully explainable
- One crew handling everything from subgrade prep through the last finish pass — no farming the finish out to whoever happens to be available
Still collecting commercial quotes? Ask each contractor what PSI they intend to pour, where the rebar spacing lands, and how the joints will be sawed. Those three answers separate a slab that runs three decades from one that starts breaking down inside its first five years — and they are the same three answers big-box tenants and their PMs already know to ask for.

FAQ
The questions North Carolina homeowners actually ask us about commercial concrete — slab thickness, Piedmont clay prep, cure-time realities, deposit terms, and what the difference is between a pour that lasts a decade and one that cracks the first winter.
Get Free QuoteWhat PSI do you pour for commercial slabs?
Standard exterior commercial slabs go in at 4000 PSI air-entrained, which handles freeze-thaw exposure across the NC Piedmont. Loading docks, dumpster pads, and heavy-truck approach lanes typically bump up to 4500 to 5000 PSI. Interior slabs on grade run 4000 PSI as a baseline, with higher strengths written in where forklift or racking loads justify them. The PSI number is set by the load, the exposure, and the return-to-service window — every commercial quote we write has the mix design listed on it in plain figures.
