Concrete Foundations & Footings in Tampa, FL
Tampa Precision Concrete forms and pours foundations and footings for home additions, garages, lanais and small new builds across Tampa. We build to the engineer's drawings, coordinate inspections, and treat the ground under your project as the first part of the job.
Foundations here sit on sand over limestone in one of the most sinkhole-prone corners of Florida, and Hillsborough, Pasco and Hernando are often grouped together as Sinkhole Alley. Add a water table that rises in the summer rainy season and a building code written around hurricane winds, and you can see why we don't pour footings off a sketch.
Foundation and footing work takes us to Valrico, Lutz, Apollo Beach, Carrollwood, Westchase, Zephyrhills, Brandon, Temple Terrace and Land O' Lakes & more.
Why Choose Tampa Precision Concrete
Foundation & Footing Services
Concrete Foundation Pours
Most Tampa homes sit on a monolithic slab, where the floor and the thickened perimeter footing are poured in one shot. We excavate the footing trench to the depth on the plans, set rebar on chairs with the cover the engineer calls for, and place the vapor retarder before the pour.
For additions, we drill and epoxy dowels into the existing foundation so the new slab and the old house move together instead of cracking apart at the seam.
Stem Wall Foundations
When a lot sits in a FEMA A zone, the finished floor generally has to be at least one foot above base flood elevation under the Florida Building Code. A block stem wall on a continuous footing, backfilled with compacted sand, is the usual way to get that height without pilings.
In coastal VE zones near the bay, fill can't support the structure, so those projects move to piles designed by an engineer. We'll tell you plainly if your project is in that category.
Soft Soil & Muck Correction
Organic muck and buried construction debris compress under load. When a soil test or our excavation finds them, we dig them out and replace them with clean, compacted fill before any steel goes in, and we price that as a line item so you can see it.
Around Tampa, low spots that were filled decades ago, old ditch lines and former citrus or pasture ground in the eastern county are the usual places we find it. A probe rod and a few test holes before forming tell us a lot.
Wind-Load Anchoring
Florida's wind provisions follow the load path from the roof down into the footing. We set anchor bolts, straps and hold-down embeds exactly where the plans show, because a strap that misses its mark by a few inches can fail inspection.
We also photograph every embed before the pour. If an inspector or engineer has questions later, the record shows where each anchor went.
Footings for Lanais & Carports
Screen rooms, pergolas and carports need isolated pier footings or a thickened slab edge sized for uplift as well as weight. We pour those to the engineered size even when the structure looks light, since it is the wind, not the weight, that usually pulls these structures loose.
Crack Assessment & Repair
Hairline cracks in a slab foundation are common and usually harmless. Stair-step cracking, doors that suddenly stick or a floor that tilts are different. We repair shrinkage cracks ourselves and refer settlement that points to deeper ground movement to a geotechnical engineer, since sinkhole repair often involves grouting the soil well below the slab.
How a Foundation Job Runs
Plans & Soil Review
We start from your engineer's drawings and any soil report. If none exists and the site looks suspect, we recommend borings before we price the work, which costs far less than a cracked addition.
Permit & Utility Locates
Your permit goes through the City of Tampa or Hillsborough County, and we call Sunshine 811 two full business days ahead of digging.
Excavate, Compact & Inspect
Footings are dug, the bearing soil is compacted, steel and embeds go in, and the building department inspects before any concrete is ordered.
Pour & Cure
We place concrete early in the day, vibrate it around the steel and keep it moist while it cures. Framing can typically follow within days.
Foundation Questions From Tampa Homeowners
Do Tampa foundations need a soil test?
For new homes and large additions, the engineer usually requires one. For a small lanai footing it may not be required, but if we see muck or soft spots we'll recommend it.
In the Plant City area, freeze-protection pumping in January 2010 dropped the aquifer sharply and was followed by dozens of sinkholes, so we take soil questions on the eastern side of the county seriously.
Can you build on a lot in a flood zone?
Yes. The foundation is designed to put the floor at or above the required elevation, usually with a stem wall in A zones and pilings in VE zones.
Does my insurance cover sinkhole damage?
Florida law requires insurers to cover catastrophic ground cover collapse, but broader sinkhole coverage is optional and costs extra. Check your policy before you plan a big addition.
How much does a foundation cost?
Foundations are priced from the engineered plans, since steel, depth and fill vary widely. Concrete runs about $145 to $195 per cubic yard here, and we'll give you a written estimate with each part listed.
What about my old slab under the addition?
We tie into it with doweled connections and match elevations. If the old slab has settled, we'll address that first.
Do you pour slabs for sheds and garages too?
Yes. Lighter work without walls is covered under our concrete slab installation service.
