Slab foundation
A slab puts the house on one solid pour sitting right on the prepared ground, so the floor stays close to the yard and there's no crawlspace to look after. It usually suits a level lot and an owner who wants the simpler build.
Planning a new home, an addition or a replacement? We help you pick a slab or raised foundation that suits your lot, then build it.

Foundation installation in Torrance means either pouring a concrete slab for the house to sit on or building a raised foundation that lifts the floor over a crawlspace, and we help you pick the one that fits your lot before we build it.
Most people who call about a foundation are building a new home, putting on an addition or replacing one that's failing, and the first decision is which kind to build, because it shapes everything after it. The price moves with that choice and with how your lot slopes, what the soil needs, the size of the footprint and how easily our crew and the concrete truck can reach the spot. The schedule mostly turns on any review the city calls for, the weather and what we find once the ground is open. I come out, look at the lot and write the estimate, so you see your own figure and what each part of it pays for. If you already know it's a slab, our slab foundation building page goes deeper on that pour.
The person who walks your lot is me, the owner, and I'm on the job alongside our crew when your foundation goes in. Nothing you told me at the estimate gets lost on its way to someone else, and you always know who to ask.
Before I started our company in Torrance in 2023, I spent years as another contractor's right hand, running the crew and sorting out the jobs that didn't go by the book. That's why we're the ones people call for tight access and awkward lots.
We're licensed and fully insured. Foundation work means deep digging, heavy trucks and a lot of concrete close to your house and your neighbor's, so it matters that the contractor on your property is covered. Ask about it when I come out to look.
I want you to understand what each part of the price pays for before we start, so nothing surprises you halfway through. Satisfaction guaranteed. When you're ready to talk about your lot, call (424) 318-3115 or send the form on this page.
We reply within one business day, and the on-site estimate is free with no obligation. Once you send this, we'll set a time for me to come out, walk your lot and write the estimate, so it helps to have the lot's slope, any soils report and whether it's a new home, an addition or a replacement handy.
Permits here go through the City of Torrance Permit Center, where applicants first get Zoning Clearance from the city's Planning or Environmental Division. We don't guess at what your job needs, because before we schedule anything we check with the city or county office for your address, and if a permit is called for, we handle the paperwork with you. The city only takes plans as digital files now, not paper, so ask whoever draws your plans for digital copies from the start.
Soil is the other thing that shapes a foundation here. The city publishes Expansive Soil Guidelines and a document on footings in its Expansive Soil Study Zone, plus an expansive soil report for the Southwood Riviera Tract, so ask early whether your property sits in that zone. The state's earthquake hazard map also marks areas where the ground may liquefy in a strong quake, and projects in one of those zones may be required to investigate that and deal with it during permitting. We're based in Torrance and work across the cities around it, including Redondo Beach and Gardena, where a lot of our foundation calls are older homes getting an addition and the first question is what the existing house is sitting on.
Start with how your lot sits, because a level lot usually points toward a slab and a sloped one toward a raised foundation. One structural engineering firm notes that raised foundations handle sloping lots without big retaining walls or hauling dirt away, and that the crawlspace keeps plumbing, mechanical and electrical lines reachable for later remodels or repairs. On a sloped lot, or a house you expect to remodel, those gains can outweigh a slab's lower starting cost.
We price each foundation after seeing the lot, since the type, the slope, the soil and the size of the footprint all change the number. The same engineering firm says slabs are economical on flat sites, and that post-tensioned slabs, which use steel cables pulled tight inside the concrete, take less labor and formwork than deep raised foundations, so the first building cost stays lower. For a level lot where the budget leads, a slab is the natural place to start comparing.
A regular slab poured right on expansive soil can move unevenly, and national engineering guidance says owners should expect it. A structural slab built over void forms, which leave an empty gap between the soil and the concrete, essentially eliminates that movement as long as the gap is kept big enough. That's why on this kind of soil the floor design gets settled first.
Roots pulling moisture out of the soil under the slab make cracking worse. It matters most where a slab goes on expansive soil, so if that's your plan, think about what you plant close to the house.
The state contractors board has a concrete contractor class for firms that form, pour, place, finish and install concrete, from mass and flat work to pavement. When you're comparing bids for a foundation, it's fair to ask each contractor what license they carry.
