A slab foundation that's square before it's poured

A slab foundation is a concrete floor poured on the ground, with the house's water and drain lines run underneath it. The price moves with the size, the grading and the steel inside, and the schedule turns on the permit and the weather. Once it's poured, you can usually walk on it within 48 hours and put heavier loads on after about a week. I'll give you your figure on site.

Plumbing goes under a slab once, so we make sure it's laid out and bedded in sand before concrete covers it, because a broken drain line down there means jackhammering the floor. Before we schedule, we check whether the City of Columbia or Maury County Building and Zoning covers your address, then handle the permit or tell you plainly what to file. Other foundation types fall under our foundation installation work.

Ways to build your slab

Get a quote
  1. Monolithic pour

    The footings and the slab go in together in one pour, which suits most house slabs on a lot that's graded and ready.

  2. Footings, then slab

    Footings are poured first and the slab after. Where a Tennessee state permit program applies, a slab under living space poured this way carries an extra slab inspection fee.

  3. Shop or garage slab

    A slab that carries trucks or equipment needs more thickness and steel, the same planning that goes into our concrete parking lot building work.

  4. Vapor retarder underneath

    A plastic sheet that slows ground moisture coming up into the floor. One maker says to check for damage well before the pour, while there's time to fix it.

Why people call us for slabs

  • I give the estimate myself

    I come out to look at the lot and give you the estimate, then I'm on the job running our crew when the slab goes in.

  • Grade and forms come first

    I framed houses on too many slabs that weren't square, so I learned flatwork and started this business in 2021. We'll spend the extra hour on grade and forms.

  • Paperwork the county asks for

    We're fully licensed and insured. For a Maury County building permit, the contractor has to show a Tennessee state contractor's license and a county business license, so ask whoever you hire.
