Concrete Floor Installation in Sioux Falls SD - a slab built for what goes on top
Floor cracked, dusty or uneven, or a new room still sitting on dirt? We pour a flat, solid slab you can finish however you like.
What goes into a new concrete floor, and what sets the price?
Concrete floor installation in Sioux Falls, SD means placing a concrete slab and then finishing, jointing and curing it so it becomes the floor you walk on, and getting those steps timed right is what helps it resist cracking, dusting and high or low spots.
Most floor calls I get are about a basement that's still gravel, a shop or outbuilding going up, an addition, or an old floor that's cracked, dusty or out of level. If it's a garage, our garage floor concrete page covers that job. The first questions I ask are how you'll use the room and how you'll heat it, because those answers shape the choices that follow.
The price moves mostly with the floor's size, whether an old slab has to be broken out, what goes under the new one and the steel or fiber inside it. The schedule turns on the weather, since a cold-month pour needs extra protection, and on any permit the job needs. I'll give you your own figure once I've seen the space. We're licensed and fully insured, and because the Sioux Falls city code sets license, bond and insurance rules for residential building contractors, it's fair to ask anyone bidding your floor about all three.
- Breaking out and hauling off an old cracked or uneven floor before the new one goes in.
- Floors for basements, shops, additions and outbuildings, finished for flooring or left bare.
- An under-slab sheet when the floor will be covered, plus the steel or fiber it calls for.
What happens after you call us about a concrete floor?
Here's how a floor goes from your first call to a slab you can walk on. I'm the one you'll see at the estimate, and I'm on site while our crew does the work.
Call or send the form
Call (605) 305-1165 or send the form and tell us a little about the space. We'll set a time for me to come out and see it.
I walk the space with you
I look at the site, listen to what you want and walk you through the choices, like what goes under the slab and which reinforcement fits. The estimate spells out what's included, so you can compare it line by line with other bids.
We plan, form and pour
Once you say yes, we line up any permit and set the pour date around the forecast. Our crew forms, pours and finishes the slab with me there.
We go over care together
Before we leave, we walk you through caring for the new concrete while it cures. That's the stretch when it's still gaining strength, so it's worth knowing what to keep off it.

(605) 305-1165Questions people ask about concrete floors in Sioux Falls
These are the questions I hear most when someone's planning a new floor. If yours isn't here, ask me at the estimate, since I'd rather answer it before the pour than after.
How much does a concrete floor cost in Sioux Falls?
A concrete slab in Sioux Falls usually costs about $6 to $11 per square foot, and that's the going rate for slab work around here, not a price from us. A floor lands lower or higher in that range mostly on its size, the prep it needs and what goes under and inside the slab. Our work is backed by our satisfaction guarantee.
Does a concrete floor need a vapor barrier under it?
If the floor will be covered with carpet, tile, wood or vinyl, industry guidance says yes, the slab needs protection from moisture rising from below. Water vapor working up through the slab can make flooring glue let go and damage the floor, so tell me what's going down before we pour. Today's under-slab sheets are tougher and tighter than the thin plastic that used to be common, so it's fair to ask what material a quote includes.
Can you pour a concrete floor in winter in Sioux Falls?
Yes, a concrete floor can go in during winter as long as the job is planned for the cold. Fresh concrete freezes once its own temperature drops below about 25°F, which can cut its potential strength by more than half, so it has to be kept from freezing until about two days after the pour. Before pouring, snow and ice get cleared and the ground under the slab has to be above freezing, which can mean insulating or heating it ahead of time and adds steps to the job.
What is the best way to reinforce a concrete floor?
Steel bars, called rebar, or welded wire add strength and help keep cracks tight, while fibers mixed into the concrete cut down on cracking but don't count as structural reinforcement. They do different jobs, so ask any bidder which one their quote includes and what it's meant to do for your floor. Two quotes that look alike can carry very different reinforcement.
How do I keep a new concrete floor from cracking like the old one?
You keep cracks under control with a firm base and control joints cut on time, because concrete shrinks as it dries and the joints give it a straight line to crack along. The sawing usually happens within about 4 to 12 hours after the pour, depending on the temperature and the mix. When you compare bids, ask how the base will be prepared and when the joints get cut.
Does a new basement floor help keep radon out in Sioux Falls?
It can, because industry guidance says a membrane under the slab that lets very little through, used with sealed joints, also blocks radon from getting into enclosed spaces where it's present. The state's environment agency puts eastern South Dakota, Sioux Falls included, in radon Zone 1 and the rest of the state in Zone 2, but it says those maps don't replace an actual test. A radon test shows your home's real level, so it's worth having before we plan what goes under the slab.
