Concrete Foundations and Stem Walls in Modesto, CA

Foundations · Modesto, CA

Footings and stem walls poured to your engineer's plans

Concrete Solutions pours concrete foundations for homes and buildings around Modesto. We form and pour concrete footings, stem walls and slab-on-grade foundations for new homes, additions, ADUs and garages. Your engineer or building designer draws the foundation. We build what those plans show, formed square and set to grade.

Most foundation jobs start when a homeowner, a builder or a general contractor hands us a plan set. We read the footing and rebar details, lay out the forms and pour. We also pour a slab or pad for a shop or shed on the same job. Call or text (209) 606-9904 for a free estimate on your plans.

Concrete footings and stem walls for homes, additions and ADUs

A stem wall foundation starts with a trench for the footing. We dig and form that footing, then set the rebar your plans call for. Short concrete walls rise off the footing and carry the floor framing above the dirt. That leaves a crawl space under the house for plumbing and ducting.

Additions, ADUs, detached garages and shops use the same parts at a smaller size. We pour the footing, form the stem wall and pour again, or pour both together when the plans allow it. Anchor bolts and hold-downs go in before the concrete sets up. Then the forms come off and your framer can start.

The structural design is not our work. Footing sizes, rebar and depth come from your engineer or building designer. We read the drawings and build what they show. The same goes on commercial jobs, where we pour footings and pads on commercial sites to the project drawings.

Stem wall foundation or slab foundation: what the difference is

A slab foundation, often called slab-on-grade, puts the floor right on the ground. The outside edges get a thickened footing, and the slab and footing pour as one piece. The finished floor ends up close to grade, and the slab itself is the floor.

A stem wall foundation sits the footing down in the ground. Concrete walls come up off that footing to carry the floor framing. The floor ends up higher, with a crawl space underneath. Builders use it where the plans call for a raised floor or where the lot slopes.

Your engineer picks the system from the soil report, the lot and the house design. Cost follows how much digging and concrete the design takes on your lot. We can talk through both at the estimate, then pour whichever one your plans show.

What Central Valley ground means for a house foundation in Modesto

The valley floor around Modesto is deep soil washed down from the Sierra. USDA soil records for the San Joaquin Valley list loams and clay loams on flat alluvial fans. Some nearby soils carry a cemented hardpan about 20 to 40 inches down. Your soils engineer tests the lot, and the plans reflect what the test finds.

Foundations are structural, so the job takes a building permit. In the city that runs through the City of Modesto Building Safety Division. Unincorporated ground nearby goes through the Stanislaus County Building Permits Division. Each of the other towns we drive to has its own building office.

Modesto's Building Safety Division says a project has to be inspected before any work is covered up. On a foundation that means the forms and the steel get looked at before concrete goes in. We set the pour after that inspection passes, and we start early through the hot months. Confirm the current permit and inspection steps with the office that covers your address.

How We Work

How a Job With Concrete Solutions Runs

From the first call or text to the cured, finished concrete, here is how it goes.

1

Call or text

Call or text (209) 606-9904 and tell us what you want poured. You can send photos of the area if you have them.

2

Site visit and measurements

We come out to look at the job, measure it and check the slope and the existing surface. This is where questions about thickness, joints and finish get answered.

3

Written estimate

You get a written estimate. It lists the area, the thickness, the finish and what the price covers.

4

Prep and pour

We form the job, grade and compact the base, set rebar or mesh, then pour and finish. Control joints get cut so the slab cracks where it should.

5

Cure and clean-up

We clean up the site and tell you how to look after the new concrete. That covers when you can walk on it, when you can drive on it and when to reseal.

FAQ

Foundations Questions, Answered

Common questions about foundations across Modesto and the Central Valley. If yours is not here, call or text and ask.

Call (209) 606-9904

What drives the cost of a concrete foundation?
Size is the biggest piece, since more square feet means more steel and more concrete. After that comes the dirt work. A sloped lot, deep footings, hardpan in the trench or tight truck access all add to it. We price from your plans at a free estimate, so call or text (209) 606-9904.
Do you repair or level an existing foundation?
No. We pour new foundations, and we do not do repair, lifting, piers or crack injection. A settling or cracked house foundation is a different trade that starts with an engineer. If flatwork is the problem, a cracked driveway can be torn out and poured new.
Do I need engineered plans before you pour a foundation?
Yes. A new home, addition, ADU or garage foundation gets designed and stamped before anyone pours. Your engineer or building designer sets the footing sizes, the rebar and the depth. Bring us that plan set and we will form and pour to it.
How long does a new foundation take to cure?
Concrete keeps gaining strength for about 28 days, and most of that strength shows up in the first week. We strip the forms once the concrete has set up enough to hold its edges. When framing starts depends on the inspection and your builder's schedule.
Does Modesto summer heat change how you pour a foundation?
Yes. Hot dry days pull water out of fresh concrete fast, which can weaken the surface and cause cracking. We start early, wet down the base and the forms, and keep the concrete damp or use a curing compound. In winter we wait out rain and cold nights instead.
Can you pour the flatwork once the house is framed?
Yes. We are a concrete contractor in Modesto that pours all phases. The same company can come back for the driveway and the walkways. Ask about the flatwork at the estimate and we will price it with the foundation.
