Concrete floor installation in Redondo Beach CA - a slab ready for your flooring
Old slab cracked, or a new room waiting on a floor? We build the base and moisture barrier around the flooring you'll put down.
What goes into pouring a new concrete floor?
Concrete floor installation in Redondo Beach means our crew preps the ground, lays moisture protection, then pours and finishes a slab that can take carpet, tile or wood later, or stay bare concrete.
Most people who call about an indoor floor are adding a room, converting a garage or replacing an old slab that's cracked or sinking, and if it's the garage slab itself you need, our garage floor concrete page covers that work. Redondo Beach Concrete Company is based in Redondo Beach and works across the South Bay and the cities around it. The price moves with the size of the floor, how much digging out and base work the ground needs, whether the slab carries steel and how hard it is to get concrete into the room. The schedule turns on that prep, the curing wait and a moisture test before any flooring goes down. When I come out, I measure and write down what's included, so you're working from your own number instead of a guess.
How we handle a concrete floor installation
Before I plan anything, I ask what flooring goes on top, because tile, wood, carpet or bare concrete each change how we build the base and where the moisture barrier sits. Then our crew digs out the soft dirt and packs the subgrade, the ground the slab rests on, so the floor doesn't settle along with loose fill. We lay the vapor retarder, a heavy plastic sheet that slows moisture coming up from the ground, and we work carefully around it because a torn sheet lets that moisture right back in. Steel goes in where the slab calls for it, then we place the concrete, finish the surface flat and cut control joints, shallow cuts that give the slab a straight place to crack instead of a random one. The base is the part you never see again and the first thing people want to trim from a budget, and I won't trim it, because a nice finish on a poor base still cracks and sinks.
A floor job often connects to work just outside the room. If the new room opens toward the pool, we can plan concrete pool decks on the same visit, and if the floor sits higher than the yard, concrete steps construction gets you in and out without a big step down.
Slab poured on a granular base
Finishers like concrete on a layer of gravel because it soaks up some of the mix water, so finishing can start sooner. It usually suits a floor that will stay bare concrete.
Slab poured right on the vapor retarder
Flooring installers prefer this setup when tile, wood or carpet goes on top. It's a choice we settle with you before the pour, because it can't be changed once the concrete is down.
What Redondo Beach houses mean for concrete floor installation
A lot of the indoor slabs we pour around Redondo Beach go into garage conversions, room additions and back rooms on narrow lots, where a truck can't pull up to the door. So we plan the route before pour day, whether that's a pump line over the side yard or wheelbarrows through a gate, because concrete stuck on a slow route starts to set before we can finish it. We see the same tight lots on jobs in Hermosa Beach and Manhattan Beach.
Before your estimate, it's worth a minute on the state's earthquake hazard map, which lets you check from a phone or computer whether your lot sits in an earthquake hazard zone. If yours does, tell me when I come out so we can talk it through with the rest of the job.
Concrete floors and slab work
Why call us for your concrete floor
I come out, then I pour
I come out to look at every job myself, in Redondo Beach and across the South Bay, measure it and write down what's included, and I work alongside our crew on the pour. The person who planned your base and barrier is the one standing there while the concrete goes in.
Licensed and insured for your job
Redondo Beach Concrete Company is licensed and insured. An indoor floor means a crew working inside your house, and you should know who stands behind that work before anyone starts.
Trained on city public works crews
I learned concrete on a city public works crew, pouring sidewalks and curbs and cutting out slabs that had cracked or lifted. I started this business in 2023, and the ground work still gets most of my attention, because that's where slabs fail first.
On a floor that gets covered later, the work under the slab is what decides how it holds up, so call (424) 402-3940 or send us the details and I'll come take a look.
(424) 402-3940Tell us about the floor you need poured
Send the size of the floor, whether it's indoors and what flooring will go on top. We'll reply within one business day to set a time, then I'll come out, measure and write down what's included, with a free on-site estimate and no obligation.
Questions about concrete floors in Redondo Beach
How much does a concrete floor cost near Redondo Beach?
A concrete slab in the Los Angeles area usually costs about $7 to $14 per square foot. Reinforced slabs, with rebar, the steel that holds the concrete together, cost somewhat more per square foot there than unreinforced pads. Your own number depends on the size, the base work and how we get concrete into the room, and I write it down when I measure.
Will my new concrete floor crack like the old one?
Some small cracks are likely, and that's normal. National guidance on floor building says some cracking and curling, where slab edges lift a little, happens on every project even with the best design and proper construction. A wetter mix shrinks more as it hardens, and the control joints we cut give the cracks that do show up a straight line to follow.
Do I need a vapor retarder under an indoor concrete slab?
For an indoor floor, industry guidance says yes. It calls a vapor retarder sensible under every interior slab and treats it as required under covered floors, while outdoor slabs generally go without, so if you might add flooring later, put it in now. One maker's white paper says even small holes in it can greatly raise the moisture coming through, which can delay new flooring or make it fail.
How long before I can walk on a new concrete floor?
A new slab should be walkable within 48 hours. Concrete takes a month to fully cure, the slow hardening that gives it strength, so you may want to wait a week before moving heavier loads onto it.
How long does new concrete need before flooring can go down?
Until it passes a moisture test, since flooring makers generally require one before they install over concrete. Too much moisture left in the slab can make a finished floor come loose, peak, break down or grow microbes. Build the test into your schedule before you book the flooring crew.
What does a concrete contractor license cover in California?
It covers forming, pouring, placing and finishing flat concrete work, which is how the state licensing board defines a concrete contractor. An indoor floor slab is that kind of work, so it's worth asking any crew for their license before they start.
