Concrete Slab Installation in Tampa, FL
Tampa Precision Concrete pours slabs for sheds, detached garages, workshops, generators and equipment pads across Tampa. We build each one for the load it will carry and the ground it sits on, then finish it to the height your permit and flood zone require.
Slab work around Tampa Bay starts with two questions: how high does it need to sit, and what is buried under it? A slab in a FEMA flood zone may need to meet a set elevation, and a backyard that was once a low spot may hide soft organic soil that will settle under a heavy shed.
Slab customers call us from Riverview, Brandon, Plant City, Wesley Chapel, Lutz, Oldsmar, Town 'n' Country and Citrus Park, and from the rest of Hillsborough and Pasco & more. We time every slab around the summer storms, and our notes on pouring concrete in Tampa heat and rain explain how.
Why Choose Tampa Precision Concrete
Concrete Slab Services
Concrete Slab Installation
We excavate organic topsoil, compact the sand beneath in lifts and pour a slab sized to the job, typically 4 inches for light use and thicker with turned-down edges where walls or heavy equipment will bear.
On flatwoods sands such as Myakka, Florida's state soil, the water table can rise to within 10 inches of the surface for months at a time. We keep the slab high enough and compact the base dry enough that it doesn't sit in standing water every summer.
Plain broom-finish slabs typically run $6 to $9 per square foot. A 12 by 16-foot shed pad at that rate is about $1,150 to $1,730, though small slabs may fall under our minimum of $600 to $1,500.
Generator & AC Pads
After a hurricane season like 2024, when Milton made the closest landfall to Tampa Bay since 1921, many homeowners added standby generators. We pour those pads level, at the elevation the installer specifies, with anchor points for the unit.
We also set the pad above surrounding grade so the generator isn't sitting in rainwater after a tropical storm, which is exactly when you need it to run.
Shed & Workshop Slabs
Prefab sheds in Florida have to be tied down for wind. We pour thickened edges or set embeds where the anchors go, so the building and the slab work as one piece in a storm.
Garage & Carport Slabs
Detached garages and carports carry vehicles and post loads. We use thicker sections at the posts, reinforce for the vehicle weight, and slope the floor toward the door so water tracked in during a storm drains out.
We also set the slab edge so that a garage door seals against it. A low spot at the door lets wind-driven rain in during a summer squall.
Flood-Zone Elevation Work
Tampa homes in A zones fall under a Florida Building Code rule of lowest floor at least one foot above base flood elevation. For accessory buildings and additions, we form and fill to the elevation shown on your survey or plans instead of guessing.
Keeping slabs above grade also helps keep termites, mildew and stormwater out of whatever you store inside.
Slab Replacement
Old slabs that cracked into pieces or sank over buried debris come out at $2 to $5 per square foot. We dig past the problem material and rebuild the base before pouring.
From Bare Ground to Finished Slab
Measure & Check Elevations
We confirm the footprint and look up the flood zone. If your project needs a survey with NAVD 88 elevations, we tell you upfront so it doesn't hold up the permit.
Permit, Locates & Dig
We file with the City of Tampa or Hillsborough County, call Sunshine 811, then strip vegetation and probe for muck or construction debris.
Base, Forms & Steel
Sand is compacted in lifts, a vapor barrier goes down where the slab will be enclosed, and rebar or mesh goes in on chairs along with any anchor embeds.
Pour & Wet Cure
Bay Area ready-mix runs about $145 to $195 per cubic yard, so we order to the yard and pour early in the day. The slab stays damp during curing to resist heat cracking.
Concrete Slab Questions in Tampa
How thick should a shed slab be in Tampa?
Four inches with thickened edges suits most sheds. Workshops, garages and heavy equipment call for more. We size it to the load and the anchoring the shed manufacturer requires.
Do I need a permit for a slab?
Most slabs do. Tampa files them under residential site permits, and Hillsborough County handles unincorporated addresses through HillsGovHub. We take care of either one.
Why is the price higher than a slab up north?
It may not be. Our plain slabs start at $6 per square foot. What can add cost is extra fill to reach a flood elevation, or digging out muck. Our 10 to 15 percent debris cushion covers that and only gets billed if used.
Can you pour a slab in a flood zone?
Yes. We build to the elevation your permit requires and keep drainage moving around the slab rather than trapping water against a neighbor's yard.
For larger slabs, ask us whether your subdivision's stormwater plan or HOA limits impervious area. Some neighborhoods cap how much of the lot can be paved.
What happens if it rains during the pour?
We start early and watch the radar. If a storm pops up, we cover the slab and finish once it passes, which is routine here from June through September.
Can you build footings for an addition too?
Yes. For anything carrying walls or a roof, see our foundations and footings work, which is built to engineered plans.
