The short answer

Concrete Barn Slabs Polk County is a concrete contractor for metal building companies, pole barn builders and dealers selling into Polk County. We pour slabs and foundations to your engineer's sealed drawings and anchor-bolt plan, check square and level before the trucks roll, and send a written quote within 48 hours of the site visit.

A metal building concrete subcontractor you can hand the slab to

Search for a steel building in Polk County and you get page after page of building sellers. Who pours the slab is a question that lands on you.

That's the job we want. Concrete Barn Slabs Polk County works as the concrete contractor for metal building companies, erectors and post-frame builders across Polk County. We also handle concrete for metal building dealers and kit sellers who need one name to give their buyers. Slabs and foundations for buildings are our focus.

What we pour for building companies: metal and steel building foundations, pole barn slabs, barndominium foundations, detached garage and workshop slabs, aircraft hangar slabs, warehouse and commercial slabs, storage building slabs and RV, boat and carport pads.

We pour to your sealed foundation drawings and anchor-bolt layout

Your engineer designed the foundation. Our job is to build exactly that, to the letter.

  • The drawings set the spec, not our habits. Thickness, thickened edges, footings, steel and concrete strength all come off your sheets. If the site doesn't match the drawing, we call you and the engineer.
  • Anchor bolts set from your bolt plan. We build templates off your anchor-bolt layout so the pattern matches your column base plates. Embedment and projection follow the drawing, and we check spacing against the column lines before the pour.
  • Square and level checked before the trucks come. We pull diagonals on the forms and shoot grade, and we hold to the tolerances on your drawings. If the drawings don't list a tolerance, we ask your engineer rather than guess.
  • Door openings where your plans put them. Door locations get laid out from your plans so the slab lines up with your framing.
  • Fill handled the way the code reads. When a foundation bears on compacted fill deeper than 12 inches, the Florida Building Code (1803.5.8) calls for a geotechnical investigation with field density testing. If your engineer calls for density tests, they happen before we set steel.

Why the bolts matter: Florida sets design wind speeds from ASCE 7 maps by risk category (FBC 1609.3), and Florida's residential code calls for a continuous load path from roof to foundation. The anchor bolts are where that path meets the concrete. Your engineer sets the wind number. We put the steel where the drawing says. FBC wind design section.

What It Costs

Drawings, fill, access and pump needs move the number on every job. Your job gets a free written estimate after we see the site.

Scheduling so your erection crew isn't waiting on concrete

A slab that slips a week throws off your whole board. Here's how we keep you in the loop.

  • Free on-site estimate, then a written quote within 48 hours.
  • A target pour date once the permit and site are ready, and a pour-day confirmation the day before.
  • A date for when your crew can start, based on the mix and the engineer's notes.
  • Photos at each stage: forms and grade, steel and bolts, pour day, finished slab.

Weather is the wild card. The National Weather Service puts West Central Florida's rainy season at May 25 to October 10, peaking July through early September. In summer we pour early, since ACI caps concrete temperature at discharge at 95F for general building work. If a storm pushes a pour, you hear it from us as soon as we know.

How the Job Goes

  1. Send the drawings

    Call (863) 000-0000 or send your sealed foundation drawings, bolt plan and site address. A partial set is fine.

  2. Free site visit

    We walk the site for access, grade, drainage and fill.

  3. Written quote in 48 hours

    Priced to your drawings, within 48 hours of the visit.

  4. Set the terms

    We agree on permits, billing and your crew's target date.

  5. Prep and pre-pour check

    Forms, steel and bolts go in per plan. We check square, level and bolt layout, with photos.

  6. Pour day

    We confirm the day before and pour once the required inspection has passed.

  7. Handoff to your crew

    You get finished-slab photos and a start date for your crew.

Permits, inspections and who pulls what

Every permit office handles this differently, so we settle the permit question with you in writing before anything gets scheduled. Some builders pull it for the whole building. Some customers go owner-builder. Here's what local offices ask for.

  • Polk County: any building regardless of size needs a permit, and so do concrete slabs meant to support a structure. All slabs must meet setbacks from property lines and easements. The permit package includes a site plan and a foundation plan. Polk County permitting.
  • City of Lakeland: all accessory buildings need a permit, and a Notice of Commencement is needed when the job is over $5,000.
  • City of Auburndale: slabs on grade over 100 sq ft within 10 feet of the principal structure, or meant to carry a building, need a permit.
  • City of Lake Wales: new buildings, storage buildings included, need a permit from the Building Division.

We don't pour until the inspection the permit calls for has passed, and you get the photos.

Ag exemption: what it means for your customers' slabs

Plenty of pole barns here go on farms. Florida Statute 604.50 exempts nonresidential farm buildings on land used for bona fide agricultural purposes from the Florida Building Code and county or city codes and fees, except floodplain rules. Read s. 604.50.

  • Polk's ag exemption affidavit is valid only with an issued permit, and using the building as a home is a code violation. Barndominiums don't qualify.
  • Polk's permitting guide lists a non-residential farm building under miscellaneous permits, with scaled plans, a site plan and the parcel ID. Polk permitting guide.
  • The affidavit is notarized, and a false statement on it is a second-degree misdemeanor.
  • Auburndale still requires a farm building permit for land use and fire code.

An exempt building still needs a slab that fits it, so we pour ag jobs to the same engineered drawings.

Customer handoff, billing and referrals

There's more than one way to set this up. Let's talk through what fits your business.

  • Customer pays us directly. You send the customer our way, we quote them, and they contract and pay us for the concrete.
  • We bill through you. You roll the slab into your package and we work as your sub on that job.
  • Referral setup. If you'd rather just pass leads along, tell us how you want those tracked and we'll talk terms.

We don't sell buildings, so there's nothing for us to pitch your customer.

What to send us for a steel building slab quote

  • Sealed foundation drawings and the anchor-bolt plan from your engineer or building supplier
  • Site address or parcel ID
  • Building size and layout
  • Overhead and walk door locations and sizes
  • Slab thickness, concrete strength and reinforcement spec
  • Survey or site plan, if you have it
  • Your target date for the erection crew
  • How you want billing handled, and whether the customer is filing an ag exemption

Where we pour: our Polk County service area

We work across Polk County, all within about an hour of Wahneta. That takes in Lakeland, Winter Haven, Bartow, Auburndale, Haines City, Lake Wales and Davenport. See the full service area.

The ground changes inside the county. On flatwoods soils like Myakka and Immokalee, the seasonal high water table can sit half a foot to a foot and a half down for about four months a year. Up on the ridge sands like Candler and Astatula, it's more than six feet down. The region also sits on sinkhole-prone limestone. That's why we see every site before we price it.

Questions We Get

Do you pour to our engineer's drawings or your own spec?
Your drawings, every time. Thickness, footings, steel, concrete strength and bolt layout all come from your sealed plans, not from our habits. If the site doesn't match the drawing, we stop and call you and the engineer before we change anything on the slab.
Can you set our anchor bolts?
Yes. We build templates from your anchor-bolt plan, set embedment and projection to the drawing, and check spacing against your column lines before the pour. You get photos of the bolts in place before your crew shows up, so nobody finds a problem with a base plate in the air.
Who pulls the permit on a metal building job?
It depends on the job and the county, so we settle it with you in writing before scheduling. Some builders pull the permit for the whole building, and some customers go owner-builder. In Polk County, slabs meant to support a structure need a permit, and the package includes a foundation plan.
How soon can our crew start erecting after the pour?
We give you a date on each job based on the mix and your engineer's notes. NRMCA says curing should run about 3 to 7 days, and we plan the handoff around that. You'll know the date before pour day.
Does our customer pay you directly or go through us?
Either can work. One option: your customer contracts and pays us directly for the concrete. The other: you bill the slab through your own package and we work as your sub. Tell us how you run your jobs and we'll put the setup in writing before the first pour.
Do ag-exempt farm buildings still need a proper slab?
Yes. Florida Statute 604.50 exempts nonresidential farm buildings from the building code, but the building still needs a foundation that fits it. We pour ag jobs to the same engineered drawings. The exemption doesn't apply to anything used as a home, so barndominiums don't qualify.
What part of Polk County do you cover?
All of Polk County, within about an hour of Wahneta, from Lakeland and Auburndale to Bartow, Lake Wales and Haines City. Cities like Lakeland, Winter Haven and Bartow run their own permit offices, so we check the office for your site before we schedule anything. Not sure a site is in range? Call and ask.
