Concrete floor installation in Sioux City IA - a slab built for the flooring you want
Old floor cracked, uneven or letting moisture into your flooring? We pour a new slab on a packed base, planned around what goes on top.
Concrete floor installation means pouring a new slab indoors, in a basement, garage, shop or addition, over a base that's been dug out and packed. Around Sioux City most calls start with an old floor that's cracked, sunk at one corner or keeping the carpet damp. Usually the trouble started underneath. A poorly prepared base settles, leaves the slab thin in spots and drains badly, and all three lead to cracks.
I'll ask what flooring is going on top before I price anything, because carpet, tile or wood changes what goes under the slab. Size, thickness and that under-slab work move the price. The weather and any permit move the schedule, and the estimate is where I measure and write up your number. Floors are the indoor version of our concrete steps and pool decks, with the same base-first work and a roof over them.
What our concrete floor installation includes
- I'm there from look to pour. I come out to look at the job myself, and I'm on site running the crew when we pour. We've been in business since 2021, five years now.
- Base dug out and packed. We dig out and pack the subgrade, the ground the slab sits on. It's the first place people want to save money and the last place I would.
- Reinforcement shown before the pour. We'll show you how your floor is reinforced, usually with rebar, the steel laid inside the slab, before any concrete goes in.
- Fully licensed and insured. Iowa requires contractors earning $2,000 or more a year from construction to register with the state. Owners doing work only on their own property don't have to.
What goes wrong with concrete floors
| Problem | What it looks like | Usual fix |
|---|---|---|
| Settled base | What it looks like: Floor dips, or one corner sits lower than the rest | Usual fix: Tear out, dig out and pack the base, repour |
| Moisture under flooring | What it looks like: Damp carpet, cupped wood or tile coming loose over the slab | Usual fix: New slab with moisture protection underneath |
| Random cracks | What it looks like: Wandering cracks that open a little wider each year | Usual fix: Repour with joints cut early to guide cracks |
| Dusty, weak surface | What it looks like: Top layer powders, chips or wears through under foot traffic | Usual fix: Replace, poured outside the midday heat |
Patch it, replace a section or repour
- Fill the cracks. Suits a floor with a few tight cracks and no sinking, where the base underneath is still doing its job. If that's all you need, I'll tell you.
- Replace a section. When one area has sunk or broken up, we handle cutting the old slab out, fix the base under it and pour that piece back.
- A full new floor. Makes sense when cracks and dips run across the whole floor, or when the flooring you want needs moisture protection the old slab never had.
How a floor job runs
- Call or send a message. Call (712) 202-0664 or use the form, and tell us the floor size, the flooring you plan on and when you'd like it done.
- I come out and measure. I look at the spot, listen to what you want and go over the job with you, then leave you a written estimate.
- Permit and inspections. If you go ahead, we check with the city or county office where the job is, pull any permit it needs and book the inspections ourselves.
- Pick the pour date. Another state's trade guide treats air at 40°F or colder as cold weather for concrete, and early fall and late spring nights can get there, so we plan for it.
- Pour, finish, walk through. We prep the ground, pour and finish the floor, then I walk it with you before we call the job done.
What keeps a new floor in good shape
Most of a floor's life is settled before anyone sees it, in the base, the reinforcement and the joints. After that, keep water from sitting on it, and call us if a crack starts opening wider instead of staying tight, because that usually means something underneath moved.
We're based in Sioux City and pour floors for homeowners, plus some small business owners and builders, here and across the cities around it, including Sergeant Bluff and South Sioux City. If you've got a floor to replace or a new space to fill, ask for an estimate.

Concrete floor questions we hear
Does a new concrete floor need moisture protection under it?
Yes, if it's getting carpet, tile, wood or vinyl, because a national concrete industry group says protection from moisture below is required for those. The group calls a vapor retarder, a sheet that slows moisture coming up, sensible under every indoor slab. Concrete on one can show minor cracks, which the group rates a smaller risk than failed flooring.
Will my new concrete floor in Sioux City crack?
Probably a little, because a national concrete floor guide says some random cracking should always be expected and reinforcement won't prevent it. Reinforcement sized and placed right keeps those cracks tightly closed, and a packed base cuts the settling that opens bigger ones. Ask any contractor how they'll reinforce your slab, and I'll show you ours.
How much does a concrete floor cost in Sioux City?
A 200 sq ft poured concrete slab in Sioux City usually costs about $800 to $2,000 per job. Size, thickness, how much base work the spot needs and moisture protection for a covered floor move it within that. I measure and price yours on site, and the work is backed by our satisfaction guarantee.
Which Sioux City office handles permits for a concrete floor?
The city's Inspections and Permit Services takes building permit applications, and you can reach it at 712-224-5216. The city's engineering permit list names sidewalks and driveways but not floors, so a floor needs checking with that office. If you hire us, we do that checking and pull any permit the job needs.
Does radon matter for a new concrete floor in Iowa?
Yes, because a state survey found Iowa has the largest share of homes over the EPA radon action level, and by the EPA's count at least half are above it. State health guidance puts clean gravel under the slab so soil gas moves, with plastic sheeting on top to help keep it out. That sheet sits where moisture protection goes, so we plan both together.
