What goes into building a slab foundation in Fontana?

Slab foundation building in Fontana means forming, pouring and finishing a concrete slab on prepared ground so it carries a new home, addition or building, and at Precision Fontana Concrete Company most of the work happens in the planning and digging before any concrete shows up.

Most folks who call us about a slab are building something new and have drawings in hand or close to it. Small business owners call too, sometimes for a building pad next to a new concrete parking lot. If your plans call for footings and stem walls instead of a slab, our page on foundation installation covers that work.

The price moves with the slab's size and thickness, how deep the soils report says we have to dig, whether the slab is post-tensioned or tied with rebar so steel inside holds it together, and how close a truck can get. The schedule mostly runs on paperwork, because we line up the plans, the soils report and the grading permit under our license before we talk about a pour date. Your written estimate spells out what's included.

What shapes a slab foundation before the pour

A lot of a slab's life gets decided before the concrete truck pulls up, so these are the things I go over with you while the plans are still on paper.

  • The soils report comes first

    An engineer's soils report tells us what's under your lot, and that decides how deep we dig, how the slab gets reinforced and which kind of slab makes sense.

  • Digging below the footings

    The city's standard grading notes call for digging at least 24 inches below the footings, or deeper to firm native soil or bedrock, unless an approved soils report says otherwise.

  • Post-tensioned or rebar

    One trade group says post-tensioned slabs, squeezed tight by steel cables after the pour, are used on stable soil to reduce cracking and cut down on control joints, the planned cuts that guide cracks.

  • Base before the finish

    The subgrade, the packed ground the slab sits on, is hidden on day one, so it's the first thing people want to trim, but I'd cut finish work before I'd cut the base.

Slab foundation questions we hear

What does a slab foundation cost near Fontana?

A reinforced concrete slab in nearby San Bernardino usually costs about $8 to $13 per square foot. Where yours lands depends on how deep the soils report says we dig, whether the slab is post-tensioned, how thick it is and how easy the spot is to reach. Your written estimate spells out what's included so you know what you're paying for.

Who issues grading permits in Fontana?

The city's Engineering Department issues grading permits in Fontana, and grading needs one before work starts unless the building code exempts it. When a job needs a permit, we pull it under our license and work with the office ourselves. That matters, because the city warns that an owner who pulls the permit for a contractor's work takes on the project's liability, including taxes and personal injury.

What causes a new concrete slab to crack?

Most early cracks on a new slab come from a base that was raked flat instead of dug out and packed, or from control joints that were cut late or skipped. Pouring in the midday heat can also leave a weak, dusty top. We dig out and pack the ground under the slab and plan the pour around the heat, because those steps decide how the slab behaves later.

Will my slab foundation move on expansive soil?

Some, probably, because even a slab that's designed and built right on expansive soils can show a little movement and cosmetic cracking. Building one with no movement at all on that kind of soil would cost more than anyone would pay and likely couldn't be done. I'd rather tell you that before we pour than after.

How do I check if my property is in an earthquake hazard zone in California?

Type your address into the state's EQ Zapp lookup, which shows whether your lot sits in a mapped earthquake hazard zone or whether the area hasn't been evaluated yet. The state's hazard zone requirements exempt a single family frame home up to two stories that isn't part of a development of four or more units, though the city or county can be stricter. It's easier to know that before the plans are final.

Can my general contractor pour the slab foundation for my house?

Yes, a general building contractor can take the main contract if they hold the concrete license themselves or hire a properly licensed concrete contractor to do it. If you're hiring one builder for the whole house, ask them which license covers the concrete work.
