Concrete floor installation in Fort Dodge IA - a dry slab that keeps soil gas out
Finishing a basement or adding a room? We set the gravel and plastic right so your floor stays dry and your flooring lasts.
What goes into putting in a new concrete floor?
Concrete floor installation in Fort Dodge means pouring a new indoor slab for a basement, an addition or a garage over a packed gravel base and a plastic sheet, which keep soil gas and moisture from coming up into your house.
Most people who call about a floor are finishing a basement, building an addition or turning a dirt or gravel space into a usable room, and some want a new garage floor along with it. The price mostly comes down to the size of the floor, how much digging and base work the ground needs, how easily we can get concrete to the spot and whether a cold-season pour needs protection. The schedule turns on the weather, the rest of your project and any permit the city asks for. When budgets get tight, people often want to trim the base first because nobody sees it once the slab is down, and I'll steer you the other way, since a nice finish over a weak base still fails. When I come out, I write the estimate up so you can see exactly what's included.
How we handle concrete floor installation
When I first look at the space, I check where the floor goes, how water moves around it and how we'll get concrete to it. On pour day our crew digs out the soft dirt and packs the subgrade, the ground the slab sits on, so the floor doesn't settle along with loose fill. Then we spread clean gravel, lay the plastic sheet over it and set the forms, and we keep that sheet whole until the concrete covers it, because the gravel and plastic are what keep soil gas and moisture out of your house. We pour when the weather lets the concrete set up properly. Then we finish the surface for the way you'll use the room and cut control joints, shallow saw lines that give the slab a straight place to crack instead of a random one. We clean up before we leave.
A floor often brings work on the outside too. A new addition or a raised doorway usually needs concrete steps, and we can pour them while our crew and forms are already there. If the new room opens onto a pool, we build concrete pool decks as well.
Smooth floor for flooring on top
A steel-troweled smooth finish suits a basement or an addition where you'll put down tile, vinyl or carpet later, because the flooring needs a flat, tight surface under it. It's the usual choice for living space.
Broom finish for garages and shops
For a broom finish we drag a stiff broom across the wet surface, and the fine ridges it leaves give tires and boots grip when the floor gets wet or snowy. It suits a garage, a shop or a utility room where traction matters more than looks.
Floor for a new addition
An addition usually starts on fresh ground, so more of the job goes into digging out and packing the base before any concrete arrives. It also ties into a bigger project, so we plan the pour around your builder's schedule.
Concrete floor installation in Fort Dodge and nearby cities
Fort Dodge's permit table says concrete within your property line doesn't require a permit, but a new home, an addition or a new garage does. Whether your floor falls under one of those depends on the project, so we don't guess. Before we start, we work out with the city which office handles your project, and if a permit is needed, we take care of the application or help you with yours. If you'd like to check on your own first, the city asks you to call the Inspections Department at 515-576-4551 x1251, and its permits page lays out the list. The city's code enforcement office also tests and licenses contractors and inspects work done under a permit.
Iowa has the largest share of homes above the EPA's radon action level, and the EPA puts the whole state in its highest zone, where at least half the homes are above that level, so the gravel and plastic under a floor matter more here than in a lot of places. We see the same basements, additions and garage conversions on jobs in Fort Dodge, Webster City and the cities around them, and the base gets the same care at each one.

Why call us for a concrete floor
I write your estimate myself
I come out to look at the space and write the estimate, and I'm on the job with our crew when we pour. The person who answered your questions is the one making sure the base goes in the way we talked about.
Learned the trade on local jobs
Before I started on my own in 2023, I spent years as the right hand to another concrete contractor here, setting forms, running pours and fixing jobs other people rushed. Fixing those rushed jobs is why I won't cut corners on the base under your floor.
Licensed and insured in Iowa
We're licensed and insured. The state licensing department requires anyone earning at least $2,000 a year from construction to register, and that's a fair thing to ask any contractor about before you hire them.
Under any indoor floor, the base and that plastic sheet decide how the room holds up, so I'd like to see your space before anything gets poured. Send us your project or call (515) 417-2702.
(515) 417-2702Get a written estimate for your concrete floor
We reply within one business day and set a time for me to come look at the space. The estimate is free and comes with no obligation, and I write it up so you can see what's included. It helps to tell us the floor's size, what the room is for and when you'd like it poured.
Concrete floor questions in Fort Dodge
How much does a concrete floor cost in Fort Dodge, Iowa?
Concrete in Iowa usually costs about $6 to $11 per square foot installed, material and labor included. That's a statewide figure, so treat it as a guide for Fort Dodge. Your floor's size, the base work the ground needs, access and the season decide where yours lands, and I'll price it in writing after I've seen the space.
Can a concrete floor be poured in winter in Fort Dodge?
Yes, but only with protection, because new concrete that freezes early can be destroyed or left permanently weakened. One trade guide says to pour only on ground that isn't frozen, and only when no freezing temperatures are expected within 48 hours. Blankets, tarps and heaters add cost, so if your pour falls in a cold stretch, we'll help you weigh that against waiting for milder days.
Why does the plastic under a concrete slab matter?
It's the layer that keeps water vapor and soil gas from coming up through your floor. One maker's white paper says even small holes in it can significantly increase the vapor coming through, which can lead to failed floor coverings and delays. That's why we guard the sheet through the pour, so the flooring you add later has a sound slab under it.
What is the best way to keep radon out from under a new concrete floor?
State radon guidance puts a gas-permeable layer under the slab, often clean gravel, so soil gas can move freely beneath the house. The plastic sheet goes on top of that layer, so the base you choose also helps keep soil gas out. We build both into the floor.
Does a new home in Iowa have to be built with radon protection?
One Iowa law directs the state building code commissioner to require a passive method for reducing radon in new single-family and two-family homes. It applies only to homes started after the rule is adopted, so if you're building new, ask your builder how your plans handle it. We'll pour to whatever those plans call for under the slab.
How do I know if my new garage floor in Fort Dodge needs footings?
The city says a new garage needs footings based on the details of the project, so the answer comes from your plans and the city rather than a general rule. We'll go over your plans with you before any forms go up, and if yours need them, we pour concrete footings too.

Call (515) 417-2702 while your addition is still on paper, so the pour date can be planned around the weather and your builder.
