What goes into a slab foundation, from soil and drains to the pour?
A slab foundation is a concrete floor poured right on the ground, with a footing around its edge that's either thickened concrete or a short wall. When we build one in Fayetteville, the soil, the plumbing drains and the gravel underneath all get settled before any concrete shows up, because once it's poured, everything under it stays put.
Most people who call about a slab have a lot and a set of plans, and they want to know what it'll cost and when the framers can start. The price mostly moves with the size of the slab, how much the lot slopes, which type of slab it needs and what the soil is like, while the schedule turns on the permit, the plumber's rough-in and the weather on pour day. I'll measure your lot and send a written estimate with your own figure, and before we set a date I check with the city's building office so any permit and inspections come in the right order.
How do you know it's time to plan a slab foundation?
Plans calling for a slab
Your house or addition drawings show a slab on grade, and nobody has marked where the drains go yet. That's the time to sit down together, because a drain decided after the pour means breaking concrete, and waiting usually pushes back the framing date.
A lot that falls away
You stand where the house will go and the ground drops toward one corner or the street. That usually means more fill, more forming or a different type of slab, and it's better to know that before the bids come in than after.
Puddles that hang around
Water sits on the building spot for a day after a good rain, or runs toward where the house will be. That tells us the grade and drainage need work before the slab goes in, because water that gets under a foundation keeps causing trouble for years.
Work that often goes with a slab
Foundation installation
When your lot or house plan calls for something other than a slab on grade, like a crawlspace or deeper walls, this is where we start.
Concrete parking lot building
Building a shop or small commercial building? The lot around it often needs the same ground prep and drainage plan, and it's easier to plan both at once.
How we handle slab foundation building
I start with the soil, because a soils report tells everyone what the slab will sit on, and it means every bid you get starts from the same place. Next comes the drain layout. Moving a drain after a house slab is poured is a real headache, so we settle every drain spot with you and your plumber before the gravel goes down. Then our crew digs out and packs the subgrade, the ground the slab rests on, spreads the gravel and sets the rebar, steel bars that tie the slab together and hold any crack tight. We build the forms, and I check them and the grade before the truck rolls, since once concrete's in there, that's where your house is. After the pour we finish the surface and let it cure, the slow hardening that gives concrete its strength. If the budget gets tight, spend it on the ground and the drains before anything else, because a slab looks the same on day one either way and you only find out years later.
A couple of things go in under the slab that are easy to forget. Concrete industry guidance calls a vapor retarder, a plastic sheet that keeps ground moisture out of the floor, sensible planning under every interior slab, and housing researchers call a passive radon vent stack best practice in new homes, since construction is the easiest time to put one in. If your plans need deeper walls or a crawlspace, that's our foundation installation work, and if a shop or small commercial building needs paving around it, we plan concrete parking lot building together with the slab so the water has one place to go.
Slab for a new house
This suits builders and owners starting from a bare lot, and it takes the most planning up front. Drains, moisture and radon all get decided before the pour, since there's no going back under it later.
Slab for an addition
This suits owners adding a room or wing onto a house that's already standing. The trick is matching the floor height and getting the new drains to meet the old lines, so we work that out with your plumber first.
Shop or outbuilding slab
This suits a detached garage, workshop or barn that won't have much plumbing. There are fewer drains to settle, but door openings and any floor drain still get placed before the concrete goes in.

Call (479) 598-4435Why Fayetteville homeowners and builders call us for slabs
I come out and run it
I walk the lot myself before there's an estimate, and I'm on site running the job while our crew preps, forms, pours and finishes. You're talking to the person who measured your slab, not passing messages down a line.
Learned on a city crew
I learned concrete on a city public works crew, pouring sidewalks, curbs and the odd wall, and I started this business in 2020. That's where the habit comes from of working out the ground and drainage before a truck ever shows up.
Licensed and fully insured
We're licensed and fully insured. Ask that of anyone who'll be digging and pouring on your lot, because a foundation crew brings heavy trucks and a lot of weight onto your property.
City plans checked before forms
Fayetteville builds to Arkansas state building standards with its own additions, and the city's building office reviews plans for code compliance and flags issues before construction starts. When a permit's needed, we handle the paperwork and inspections, so problems come up while they're still on paper.
On a slab, the part that matters most is the part you'll never see again once it's poured, so bring every question you've got. Send us your project details or call (479) 598-4435 and I'll come take a look.
What happens after you call about a slab foundation?
Call or send the form
Tell us where the lot is and what's going on it, and we'll set a time for me to come out. Builders can send plans ahead so I've read them before I get there.
I walk the lot with you
I measure, look at the slope and where water runs, and talk through slab type and drain spots with you. Then I send a written estimate you can take your time with, so the price is on paper before you decide anything.
We check in, then prep
Once you say go, I check with the city and we line up any inspections so they fall in the right order. Our crew digs out, packs the base, spreads gravel, sets the steel around your plumber's drains and builds the forms.
We pour, finish and walk it
On pour day I check the forms and grade one last time, then we pour and finish the slab. When we're done, I walk it with you so you know exactly what your house is sitting on.
Common questions
What type of slab foundation is best for a sloped lot?
A stem-wall slab usually fits a sloped lot better, while a monolithic slab, where the footing and floor go in as one pour, suits level lots in mild climates. As general practice goes, the monolithic slab takes less labor, and the stem-wall slab takes more steps but handles slopes. I'll tell you which one I'd pick once I've stood on your lot.
How much does a slab foundation cost in Fayetteville, AR?
A reinforced concrete slab in Fayetteville usually costs about $7 to $11 per square foot, as a going rate across the area, not a price of ours. Where your slab lands in that range comes down to slope, slab type, soil and drains, the things covered up top. The written estimate after I've walked your lot gives you the number for your job.
Who issues building permits for a slab foundation in Fayetteville?
Fayetteville's building official issues permits to build or alter buildings and structures, and the city's list of exempt work names things like painting, playground equipment and flooring, not slab foundations. The city also makes field inspections on all construction, additions and repairs included. If you'd like to ask yourself, Fayetteville Building Safety asks people with questions to call 479-575-8238 and talk to an inspector.
How long does a new concrete slab need to cure before building starts?
A slab should be walkable within about 48 hours, and waiting a week before heavier loads is the safe choice, though concrete takes 28 to 30 days to fully cure. That's worth building into your schedule, so talk with your builder before stacking lumber or bringing in heavy deliveries that first week.
How do I keep water from getting under a slab foundation?
Send water away from the foundation with site grading, gutters and downspouts, and put gravel under the slab, which is what housing researchers advise. They add a drain tile, a perforated pipe that carries water off, where the soil calls for one. We set the grade around your slab so water runs away from it, and I'll tell you if I think your lot needs more.
What causes a new concrete slab to crack?
Most early cracks start with the ground underneath, usually a base that was raked level instead of dug out and packed, so it settles along with the dirt. On expansive clay, the choice is a slab engineered for that soil or a slab that moves, which is why I want the soils report first. Pouring in midday heat can also leave a weak, dusty top, so we plan pour times around the heat.
