What Torrance homes need from their concrete

We're a concrete contractor in Hawthorne, CA, a short drive north of Torrance, and most of the calls we get from here are about slabs that have been down a long time. It's usually a driveway that has cracked or settled, a backyard patio that holds water, or a front walk that's lifted enough to catch a toe, which is where our concrete sidewalk building work comes in. We do the same jobs in Del Aire and Redondo Beach, but the ground in Torrance asks a little more of us.

The City of Torrance has made its foundation rules stricter because of expansive soil, the kind that swells when it's wet and shrinks as it dries. For a driveway or a patio, that puts most of the weight of the job on the subgrade, what the slab sits on, so that's the first thing I look at when I come out to write your estimate.

What we fix on Torrance driveways and patios

  • Soil that moves under slabs

    When the ground under a driveway swells and settles, the slab cracks and pieces end up at different heights. We pack a firm base and add rebar, steel that holds the slab together.

  • Bases that were never packed

    A lot of the sinking slabs we see were poured on dirt that was raked level instead of dug out and compacted. The dirt settled, and the concrete went with it.

  • Water running toward the house

    Some older patios and driveways were poured flat or tipped back toward the house, so water pools against the wall. We check where water runs before forming anything and slope the slab away.

  • Hillside lots and sloped yards

    Parts of Torrance are hillside, and a patio or a set of steps on a slope needs the ground cut and held back before any slab goes in. Sometimes that means a retaining wall.

Should you repair or replace a cracked Torrance driveway?

If the cracks are thin and the pieces still sit level with each other, a repair usually makes sense, because the base underneath is still doing its job. Once sections have sunk or tipped, the trouble is under the concrete, and patching the top won't stop it moving. Then I'll recommend taking it out, rebuilding the base and cutting control joints, shallow grooves that give the slab a planned place to crack.

If the budget is tight, the base is usually the first thing people want to trim, because nobody sees it once the concrete is down. I'd rather you save on the finish. A plain broom finish, the light texture that gives shoes and tires some grip, over a well-packed base usually holds up better than a decorative surface poured on loose dirt, and your written estimate spells out the base work so you can see what's included.

Questions from Torrance homeowners

  • How much does a concrete driveway cost in Torrance?

    The price of a Torrance driveway comes down to its size and thickness, how much old concrete has to come out, how much digging and base work the ground needs, and the finish you choose. The schedule turns on whether the job needs a permit and on curing, the wait while new concrete hardens before you can walk on it and then drive on it. I'll come out, look at the job and give you a written estimate that lists what's included and what isn't.

  • How do I get a permit for a concrete driveway or patio in Torrance?

    Construction permits in Torrance come from the city's Building and Safety Division, and I'll tell you at the estimate whether your job needs one. If it does, we handle the application with that office and arrange the inspections. The city asks for zoning clearance before the application goes in and takes all permit submittals electronically, and you can follow the status on its online citizen portal.

  • What work is exempt from a building permit in Torrance?

    A draft city ordinance lists some exempt work, such as small one-story detached sheds and playhouses, low fences, and finish work like painting, tiling, cabinets and counter tops. The examples it gives don't include driveways, patios or slabs, so it doesn't settle whether your concrete job needs a permit. The city has also said it's making the exempt list stricter to fit local conditions, which is why I check each job instead of assuming.

  • When does a concrete contractor need a license in California?

    Under the Contractors State License Board's guidance, a contractor needs a license when the project requires a building permit, uses any additional workers, or the labor and materials on one or more contracts add up to $1,000 or more. A bigger job can't be broken into smaller contracts to stay under that $1,000 mark. We're fully licensed and insured.

  • Does a contractor need a Torrance business license to work in the city?

    Yes, Torrance requires a business license for any company located in the city or that will physically work there. That includes contractors based in other cities, and it also covers anyone delivering into Torrance in their own vehicles.

  • How do I check if my Torrance home is in an earthquake hazard zone?

    You can enter your address in the California Geological Survey's EQ Zapp map, which shows whether it lies within any mapped earthquake hazard zone. It also tells you if the survey hasn't evaluated your area yet. The city ties its stricter soil investigation rules partly to the faults nearby, which bears most on foundation and slab work.
