What goes into building a slab foundation for a new home or addition?
A slab foundation is a concrete foundation that sits right on the ground and carries your house, and in Dixon we build it by prepping the ground, laying the moisture layer, then forming, pouring and finishing the slab, often along with footings and drainage work around it.
Most people who call about a slab are building a new home, an addition, a garage or a shop, or they're replacing an old slab that cracked and settled. The price moves with the slab's size and thickness, whether it's a standard slab or a post-tensioned one, how much dirt has to come out and get packed back in, and how easy it is to get a concrete truck to the spot. The schedule turns on getting the soils input and the design settled, then the permit and the inspections. If the job needs a permit, we pull it and set up the inspections. The estimate is where you get your own figure.
How do you know it's time for a new slab foundation?
Cracks running across floors
A crack that runs through several rooms, or one with one side higher than the other, usually means the ground moved under the old slab. Waiting lets water get into the crack and the soil below, and the repair gets bigger every wet season.
Damp floors or lifting flooring
Flooring that cups, peels or smells musty often means moisture is coming up through the slab because the layer under it is missing or torn. Left alone, it keeps ruining new flooring and can lead to mold.
Doors that stick and gaps open
Doors that start rubbing, and gaps opening at baseboards or around windows, can mean the slab is moving with the clay. The longer it goes, the more of the house above it gets pulled out of square.
Work that often goes with a slab
Foundation installation
Some lots and house plans call for a raised foundation or stem walls instead of a slab on the ground, and we can talk through which fits yours.
Concrete parking lot building
A new shop or small commercial building on a slab usually needs paved parking too, and planning both together keeps the grading and water flow working as one.
How we handle slab foundation building
We start by checking where water runs across the lot, then dig out the subgrade, the soil the slab sits on, down to firm ground and pack it so it won't settle later. We set the forms, lay the moisture layer and patch every hole in it before anything else goes in, because a small tear under a slab lets water vapor come up through your floors for years. Then the rebar, the steel that holds the concrete together, or the cables for a post-tensioned slab go in to the design, and we pour early in the day so the heat doesn't leave a weak, dusty top. If you're leaning toward post-tensioning, I want the soils input early so the design isn't rushed. And if the budget has to give somewhere, I'd rather keep the money in the base than in the finish, because nobody sees the base on day one and it's the one part you can't redo.
A slab often comes with other concrete work. If your plans or your lot point to a raised floor or stem walls, our foundation installation work covers that instead. Small property owners putting up a shop or office often pair the slab with concrete parking lot building, so the paving and the building drain the same way.
Conventional slab with rebar
This suits most additions, garages and shops on steadier ground, with the steel grid inside holding the concrete together if it cracks. It's the simpler build, and the thickness and steel come from your plans.
Post-tensioned slab
Steel cables run through the slab and get pulled tight after the pour, squeezing the concrete so cracks stay closed. It's the one to ask about on clay that moves a lot, and it needs an engineered design, so we bring it up early.
Replacing an old slab
This is for a house or building whose slab has cracked and settled past repair, and it means breaking out the old concrete and starting the base over. It's structural work, so it takes more planning than a new pour on open ground.

I look at every job myself
I come out to see every site, and I'm there running our crew on the day the work gets done. The person who planned your slab is the one standing there when the truck shows up.
Licensed and insured for concrete
We're licensed and insured. You can check any contractor's license with the state licensing board before you sign anything, ours included.
Water planned away from the slab
On Solano County clay, keeping water off the ground is the biggest thing you control, so we look at grading and where your downspouts drop before we set a form. A slab that sheds water away from the house gives the clay under it less reason to swell.
Back in concrete since 2023
I poured flatwork, the slabs, drives and walks, when I was young, then came back to concrete and started this business in Dixon in 2023. We're known for quick replies and straight answers, including what concrete can and can't do.

Call (707) 640-8084 or use the form, and tell us where the property is and what you're building. We get back to you and set a time for me to come out.
I walk the site with you
I look at the ground and where the water goes, and I ask how you'll use the building. Then you get an estimate for your slab, with what moves the price laid out plainly.
Permits, prep and the pour
If the job needs a permit, we pull it and set up the inspections, and Dixon inspections run Monday through Thursday, 8 AM to 3:30 PM, so we time the prep and the pour around those days. Then we dig out, pack the base, set the moisture layer and pour.
Curing walkthrough before we leave
Curing is the wait while the concrete gains strength, and loading it too soon can weaken it. Before we leave, I walk you through what to do and when the next trade can start.
Common questions
How much does a slab foundation cost in Dixon, CA?
The price comes down to the slab's size and thickness, the slab type, and how much ground work your lot needs before the pour. A post-tensioned design, engineering, a lot of dirt to haul and a tight spot for the truck all push it up, while a simple shape on firm, open ground keeps it down. I give you a figure after I've seen the site.
What type of slab foundation is best for clay soil in Dixon?
On shrink-swell clay, the clay that swells when wet and shrinks when dry, a post-tensioned slab is worth asking about. One post-tensioning trade group calls it a cost-efficient choice for homes on that kind of soil and says it cracks less and keeps any cracks tight, which helps keep water and bugs out. About half the soil in Solano County is that kind of clay, so the ground under your lot should drive the choice.
Do I need a soils report for a slab foundation in Dixon?
For a post-tensioned slab, plan on one, because a geotechnical engineer, a soils specialist, supplies the soil numbers the design is built on. Whether the city needs a report or engineered plans for your particular slab is something we sort out at the consult. If we're not sure, we ask the city or county before we start.
How do I submit a building permit in Dixon, and what fees apply?
The City of Dixon takes permits through its online permit system, Dixon Civic Access, unless special arrangements are made ahead of time. On top of the permit fee there may be state fees and a city surcharge, and new construction may also carry city and Solano County impact fees, so budget beyond the base fee. When your job needs a permit, we pull it for you.
What license should a slab foundation contractor have in California?
Look for the board's C-8 concrete class, which covers forming, pouring, placing and finishing concrete. If you're going post-tensioned, ask who handles the tensioning, since that work falls under a separate D-6 class that leaves out installing the rebar. If you're replacing a slab under an existing house, ask which class the contractor holds, because a residential remodeling contractor can't contract for structural foundation work.
How do I keep moisture from damaging new floors over a slab?
Protect the moisture layer under the slab, because one maker of these layers found that even small holes can greatly raise the water vapor coming through the floor. That can mean failed flooring and delays before it can go down. Ask any crew how they keep that layer whole while the steel goes in and the pour crew walks on it.
