Why Homeowners Hire Us for Concrete Slabs

A slab is only as good as what's underneath it. We grade, pack, and prep the base before any concrete goes down, so your finished slab won't crack, settle, or move with the cold weather we get here.

Whether it's a 100 sq ft shed pad or a 1,200 sq ft garage floor, we size the thickness and reinforcement to fit what you're putting on it. Hot tub, RV pad, shop floor, HVAC pad, we've poured them all.

How We Layer Every Slab

The order is what most installers shortcut. We pack a gravel base, lay a vapor barrier on top of it, then set the steel reinforcement on chairs above the barrier: gravel, then vapor barrier, then steel, then pour. The barrier keeps ground moisture from wicking up into your slab, and the steel sits where it'll actually carry the load.

Concrete Slab Types We Pour

Every concrete slab in Greenville SC is sized, reinforced, and prepped for what's going on top of it. A garage pad isn't the same as a shop slab, and we won't pour either one wrong.

Concrete Slabs Built for Upstate SC Red Clay

Upstate South Carolina sits on heavy red clay that shrinks in summer and swells in winter. A slab poured without proper base prep and a moisture barrier will show that movement as cracks within two seasons. We strip the topsoil, pack a stone base on top of the clay, and lay a heavy vapor barrier where the slab will be enclosed or insulated.

When your project calls for reinforcement (and most do), we size it to the load: a standard steel grid for residential garage pads, a heavier steel mat for shop slabs that hold equipment or vehicles, and fiber mixed into the concrete for smaller residential pads under 200 square feet.

Frequently Asked

Real Answers, Upstate SC Prices.

How thick should a concrete slab be in Greenville SC?
A residential garage or carport slab is typically 4 inches thick. Reinforcement isn't a default, but most residential slabs end up using #4 rebar on 18-inch centers. Shop slabs that hold equipment or vehicle work typically run 5 to 6 inches and most use rebar mat reinforcement. Generator and equipment pads are usually 6 inches with engineered rebar sized to the unit weight. We spec every slab during the on-site estimate.
Do concrete slabs in Upstate SC need rebar or is wire mesh enough?
Rebar isn't required by default, but most load-bearing slabs in Upstate SC's freeze-thaw climate end up using it. We recommend #4 rebar on a defined grid whenever the slab will carry vehicle weight, equipment, or a structure on top. Welded wire mesh is acceptable for very small residential pads under 100 square feet with no structural load.
How long does a concrete slab take to cure before I can use it?
A residential concrete slab in Greenville SC is walkable at 24 to 48 hours, ready for furniture or light equipment at 7 days, and fully cured to its 28-day design strength at four weeks. Heavy vehicle or equipment loading should wait until 14 to 28 days depending on slab spec. We provide a written cure schedule with every pour.
