How much does a concrete slab cost in Savannah?
Pads and slabs price to the load and the ground: reinforcement matched to the use, a base packed over a high tidal water table, and a grade that sheds water off. For an honest opening figure, most pads and slabs come in around $7 to $13 a square foot, with thickness and any vapor barrier nudging it. We size and price the pad against whatever it has to carry.
What reinforcement goes in a slab here?
On most residential pads we run structural fiber through the batch and welded wire mesh across the slab, which is routine coastal Georgia flatwork. When the load turns genuinely heavy or structural, a shop floor parking trucks or a pad near the port being the clear case, a steel rebar grid goes in, because hauling that kind of weight is the job rebar was made for. We match the reinforcement to the load in front of us instead of packing a light pad with steel that only feeds corrosion in coastal salt air.
How thick does my slab need to be?
That follows the load. A shed pad carries a fraction of the weight a garage or shop floor under vehicles and gear has to hold, so we match thickness and reinforcement to your actual use and account for the soft coastal ground and high water table below it.
Will a slab hold a hot tub, RV, or boat?
Yes. Those are heavy, concentrated loads, so we step up the thickness and the reinforcement and bring in rebar wherever the load truly asks for it. A boat or RV on Lowcountry ground also wants a level base that will not shift as the soil wets and dries with the tide, which makes drainage count every bit as much as the steel. Name the boat, RV, or rig and we build the pad to carry it.
Do I need a vapor barrier under the slab?
For enclosed or conditioned slabs, usually yes, since a high tidal water table and damp coastal ground drive moisture up through concrete. We make that call based on how the slab will be used.
Does a concrete slab require a permit?
Some do, depending on size, placement, and use, and the rules differ across the City of Savannah, Chatham County, and the smaller jurisdictions nearby, with extra review common inside the flood plain and the historic district. We call out when a permit looks likely so it gets handled early instead of surfacing mid-job.
