When your plans call for a slab foundation, a concrete slab resting on the ground that the house, addition or garage sits on, everything built afterward depends on it. It has to be flat, square and dry, and it's the one pour in a building you can't easily redo.

Our crew digs out and packs the subgrade, the ground the slab sits on, then sets straight forms and places the steel before the truck arrives. When budgets get tight, the base is the first thing people want to cut because nobody sees it, but I'd rather trim elsewhere, since a slab only holds steady if what's under it does.

The price mostly follows the slab's size and thickness, how much digging the lot needs, the steel and whether a vapor retarder goes in. The schedule turns on the city permit, which we prepare and file for our part of the work, and on a pour date that suits your site. Your written estimate spells out what's included.

You can count on straight forms, finished prep and plain answers before any concrete shows up, so please call (424) 452-9329 with your questions.

Slab foundations we form and pour

We fit the slab to the building on it and the ground under it. A raised floor on perimeter walls is foundation installation, and paving a lot is concrete parking lot building.

  • Reinforced slab on grade

    This is the common slab, poured on packed ground with rebar, steel bars tied in a grid so the concrete holds together under load. We thicken the edges where walls bear.

  • Post-tensioned slab

    Steel cables run through the slab and are pulled tight once the concrete has gained strength, squeezing it together. It's often chosen for ground that moves, as the questions below explain.

  • Vapor retarder underneath

    A vapor retarder is a sheet laid under the slab to cut down the water vapor rising through it from the ground. Not every bid includes one, so please ask each contractor.

Why owners choose Manhattan Beach Concretefor the slab under their home

Working with us is plain and steady. I explain what concrete normally does, what we'll do about it and what comes next, so nothing about your slab comes as a surprise.

  • The owner sees it through

    I come out to look at the job and give the estimate myself, and I stay involved until your slab is finished, so you're never passed along to someone new.

  • Our own crew on your pour

    The people forming, pouring and finishing your slab are our own crew, so the care we put into the prep carries straight through to the finish.

  • Straight forms since 2020

    I learned under an old-school boss who made me pull and reset forms until they were straight, and I've run this business the same way since 2020.

  • Joints and moisture in writing

    We talk through how the joints will be laid out and whether a vapor retarder goes under the slab, then spell both out in the estimate, so you know what you're paying for.

  • Licensed and fully insured

    California's Contractors State License Board licenses concrete contractors for forming, pouring, placing and finishing, so please ask every bidder about theirs. Our promise is simple. Your satisfaction, guaranteed.

How your slab job runsfrom first call to walkthrough

We keep it simple by putting everything in a written estimate first, so you can see what's included and decide before anything is ordered or dug.

  1. You call or send the form

    Call (424) 452-9329 or send the form with your address and what you're planning to build. We'll set a time for me to come out and see the lot.

  2. I look and listen

    I walk the site and hear what you need before I take a single measurement. Then you get a written estimate that says exactly what's included.

  3. Permit and ground prep

    Once you say yes, we file the permit for our part and wait for it, because the city allows no work until it's approved and issued. Then we dig out, pack the base and set forms.

  4. The pour and finish

    Our crew pours and finishes the slab while I check it as it goes. The city's usual construction hours are weekdays 7:30 AM to 6:00 PM and Saturdays 9:00 AM to 6:00 PM, with none on Sundays or city holidays.

  5. Walkthrough and curing

    We walk the finished slab with you before we pack up. Then it needs time to cure, the slow hardening that gives concrete its strength, before framing goes on it.

Slab foundation questions

How much does a slab foundation cost in the Los Angeles area?

A concrete foundation or reinforced concrete slab in the Los Angeles area usually costs about $5 to $14 per square foot. That's the going rate around the area, not our quote, and where your slab lands depends on its size and thickness, the digging and base work, the steel and whether a vapor retarder goes in. Your written estimate gives your own figure.

Does a slab foundation in Manhattan Beach need a permit?

The city's Building and Safety office issues permits for all construction work, and while its list names decks, pools and most excavation rather than slab foundations, it's the place to confirm what your slab needs. We prepare and file the permit for our part of the work. Plan for the city's recycling rule too, since new homes, additions that add size and all demolition must recycle at least 65% of their waste.

Will my new concrete slab crack?

Some cracking is normal, because cracks in concrete can't be prevented entirely, but well-planned control joints, grooves cut so the slab cracks along lines we choose, keep them in check. Wire mesh won't stop cracks either, though it tends to keep cracks and joints from opening up. That's why we lay out the joints with you before the pour.

What is the best slab type for soil that shrinks and swells?

The Post-Tensioning Institute, a trade group, calls post-tensioned slabs a cost-efficient, high-performance choice for homes on shrink-swell soils. If your ground swells when wet and shrinks when dry, it's worth asking whether that slab type fits your lot, and we're glad to talk it through at the estimate.

What causes a new slab foundation to settle or crack early?

Usually it's the base, when the ground is raked level instead of dug out and packed, so the slab settles with the dirt under it. Joints cut late or skipped, a pour in midday heat and water running toward the house cause trouble too, which is why we plan all of it before the truck comes.

How do I know if I need a coastal permit in Manhattan Beach?

You need one if your lot is in the city's Coastal Zone, because all projects there must get a coastal permit unless they're exempted or excluded. Please check your address on the city's planning permits page and add that step to your plans before you pick a pour date.
