Concrete Slab Installation in Charlotte, NC
Charlotte Concrete Services pours concrete slabs for garages, sheds, workshops, carports, HVAC units and standby generators, and replaces or levels slabs that have cracked or sunk.
Charlotte slabs face slow-draining red clay, about 43 inches of rain a year, humidity that pushes moisture up through concrete and termite pressure. Ours get a compacted GAB base, a vapor barrier where enclosed, thickened edges to Mecklenburg County's 12-inch footing depth, and steel throughout.
We pour from Steele Creek to University City and out to Matthews & more. Cure time is covered in how long before you can drive on new concrete in Charlotte.

Concrete Slab Services
Concrete Slab Installation
We compact the clay, lay a 4-inch GAB base, set rebar or wire on chairs and pour a level 4-inch slab, thicker where needed. Slabs run $7 to $15 per square foot installed, so a 12 by 16 shed pad is roughly $1,344 to $2,880.
Slab Replacement
A slab split into pieces or sunk at a corner is past patching. We break it out for $2 to $6 per square foot, rebuild the base and repour with fresh steel.
Garage & Carport Slabs
Garage floors that crack or hold water at the door lacked a base or a proper fall. We pour thickened, reinforced edges, a pitch to the door and isolation joints, to plans permitted through Mecklenburg County Code Enforcement.
HVAC & Generator Pads
Plastic AC pads sink into the clay and tilt your condenser. We pour level, reinforced pads for condensers, heat pumps and standby generators to the manufacturer's clearances.
Slab Repair & Leveling
If a slab is in one piece but has dropped, lifting beats replacing. Concrete leveling raises sunken slabs, and crack repairs run $3 to $8 per square foot.
Shed & Workshop Floors
A shed on blocks lets moisture and critters underneath. A poured floor with a vapor barrier keeps tools dry through humid summers, and larger buildings are poured to permitted setbacks.
How We Pour Your Slab
Plan the Slab
We confirm use, load, size and drainage, then quote thickness and reinforcement.
Excavate & Compact
After NC 811 locates, we dig to firm clay, compact the subgrade and place GAB in lifts.
Barrier, Steel & Forms
Enclosed slabs get a vapor barrier after termite pretreatment, then steel on chairs and forms set level or to pitch.
Pour, Finish & Cure
We pour, finish with broom or trowel, cut control joints and cure. Full strength comes at 28 days.
Slab Questions From Charlotte Customers
How much does a concrete slab cost in Charlotte?
Most slabs run $7 to $15 per square foot installed; a 24 by 24 garage slab is around $4,032 to $8,640.
How thick should my slab be?
Sheds, patios and HVAC pads do fine at 4 inches. Garages get 5 to 6 inches with thickened edges.
Why does my garage floor sweat in summer?
Humid air condenses on a cool slab, and moisture wicks up from wet clay without a vapor barrier.
Do I need a permit for a shed slab?
Small sheds often do not, larger buildings do. Rules differ between Charlotte and Cabarrus, Gaston or Union jurisdictions.
Can you pour on a sloped backyard?
Yes. We cut into the slope, build up with compacted fill and a turned-down edge, or add a short retaining wall.
When can I build on the new slab?
Light framing after three to seven days, vehicles after a week, design strength around day 28.
