Slab foundation building in Davis CA - built for the soil your house sits on
Planned around your soil, from base to pour
Slab foundation building means pouring the concrete floor your house sits on, right on the ground. Most calls come from people putting up a new home, an addition or an ADU in Davis or the cities around it. I walk the lot first, then we build the slab to fit your soil and your plans.

Why a slab foundation makes sense for your build
A slab foundation is one pour of concrete that sits on the ground and carries the house. We grade and pack the subgrade, which is the dirt the slab rests on, set the forms and steel, then pour and finish. If your plans call for a raised floor, that's foundation installation instead.
The price moves with the square footage, the slab type and what your soil calls for. The schedule depends on permits, the weather and the cure. You get your own number when I walk the lot.
Best for
- New single-story homes
- Additions and ADUs
- Lots with shrink-swell soil
Floor and foundation in one
The slab is your foundation and your ground floor at once, so there's no crawl space to vent, check on or keep critters out of.
Steel that holds it together
Rebar is the steel grid set inside the concrete, and it holds the slab together when the ground moves or the concrete shrinks as it dries.
Water runs away from it
We set the pad high and grade the dirt around it to fall away, so rain doesn't sit against the edge of your house.
Ready for the framers
Once the concrete sets up, the framers get a flat, square deck to build on, with the under-slab plumbing already in place below it.

What keeps a slab foundation flat and tight for years
- Our crew lead runs the site, I do the walk-through, and I'm there for the pours, which we start early to stay ahead of the midday heat.
- Years running crews taught me that the trouble starts before the truck arrives, so we dig out and pack the base as if it were going under a parking lot.
- We're licensed and fully insured, and the state licensing board licenses concrete contractors in California, so check anyone who bids on your slab.
Choosing the slab that fits your lot
I go over whether a post-tensioned slab or a conventional one fits your lot, and if there's a soil report, we build to what it says.
Post-tensioned slab
Steel cables pulled tight after the pour squeeze the concrete together, and they're worth a look on soil that shrinks and swells.
Conventional rebar slab
A grid of rebar tied in before the pour suits steadier ground and straightforward plans.
Monolithic slab
The edge footings and the floor go in as one pour, which suits smaller buildings like ADUs, shops and garages.
Stem wall and slab
A short concrete wall goes in first and the slab is poured inside it, which helps on a sloped lot or with a floor set higher.

Slab foundation questions we hear
How much does a slab foundation cost near Davis, CA?
A slab foundation in the Sacramento area usually costs about $6 to $22 per square foot installed. That's the going rate in the region, not our price. Where yours lands depends on size, slab type, site grading and what any soil report calls for, and I'll price your lot when I walk it.
When can I walk on a new concrete slab foundation?
You can usually walk on it within 48 hours, though concrete takes 28 to 30 days to fully cure, the slow stretch where it keeps gaining strength. Waiting a week before putting heavier loads on it may be safer, so plan lumber drops and equipment for after that.
Will my new slab foundation crack?
Yes, a few cracks are normal on every slab, even with the best design and careful building. Our job is keeping them tight, which is why we pack the base, place the steel right and time the finishing. The Post-Tensioning Institute says post-tensioning reduces cracking and keeps cracks tight, which helps keep water and bugs away from your flooring.
Is a post-tensioned slab right for my lot in Davis?
It's worth asking about if your soil shrinks and swells, because the Post-Tensioning Institute calls post-tensioned slabs a cost-efficient, high-performance answer for home foundations on that kind of ground. They can often go in faster than a comparable rebar slab, too. I'll tell you which one I'd pick for your lot at the walk-through.
Do I need a soil report for a slab foundation in Yolo County?
You do if your lot is in a subdivision under Yolo County's rules where the soils report found critically expansive soil or other problems. Each lot then needs a soil investigation by a state-registered civil or geotechnical engineer, and the county requires later building permits to follow the fixes it recommends. We check with the city or county for your address and take care of any permit the job needs.
