Garage floor concrete in Atherton CA - a floor built for the weight it carries
Garage floor cracked, sinking or chipping? We pack a solid base, plan the joints with you and pour a slab built to carry your cars.
What does a new garage floor in Atherton involve?
Garage floor concrete in Atherton is the flat slab our crew forms, pours and finishes as the floor of your garage. It sits on a packed base and is built thick enough to carry your cars day after day.
Most calls start with a garage floor that's cracked, sinking at one corner or dusting and chipping on top, or with a new garage that needs its floor. The job is mostly ground work. We dig down, pack the base and set the forms and steel, then pour, finish and cut the joints. If you'd like color or polish on top, that's where decorative concrete comes in.
The price moves with the size of the garage, how thick the slab needs to be, how much base work the ground calls for, the reinforcement and any prep for a coating. The schedule turns on whether a permit is needed, the weather around pour day and the wait before you can park on the new floor. Your own number comes from the written estimate I give you after walking the garage.
What a good garage floor slab needs
Most of what decides how a garage floor holds up happens before the concrete truck shows up, so here's what I'd want you to know going in.
The base underneath
The subgrade, the ground the slab rests on, should be packed firm and drain well. It's hidden once the concrete is poured, so it's the first thing people cut and the last thing I would.
Thickness for the weight
Home floors around the Bay Area usually run four to six inches thick, and garage slabs sit at the thicker end because they carry cars every day.
Steel or fiber inside
Rebar, which is steel bars set inside the slab, and welded wire both reinforce the concrete. Fibers mixed into the concrete reduce cracking but add no structural strength.
Where the water goes
The floor should fall toward the door and away from the house so water off wet tires runs out. If your garage sits below a slope, concrete retaining walls may belong in the plan.
Garage floor questions we hear
How much does a new garage floor slab cost in the Bay Area?
A reinforced concrete slab in the Bay Area usually costs about $9 to $16 per square foot, before any staining or stamping. That's the going rate for the area, not our price, and where your floor lands depends on the size, thickness and base work it needs. I'll give you your own number in writing after I walk the garage.
Will my new garage floor crack?
Some cracking over time is normal, because nobody can stop concrete from cracking entirely. Control joints are planned lines cut into the slab, and they decide where cracks form and keep them small. Wire mesh won't prevent cracks, but it tends to keep them from opening up, so ask any contractor where the joints will go before the pour.
How long does a new garage floor take before I can walk and park on it?
You can usually walk on it within 48 hours, but give it a week before you park a car on it. Curing, the slow hardening that gives concrete its strength, takes about a month in full, so plan somewhere else to park for that first week.
Who issues building permits in Atherton, CA?
The Atherton Building Department issues permits for building, altering, demolishing and moving buildings and structures, and it inspects the work it permits. We look into whether your floor needs a permit before we quote. When it does, we handle the application and meet the inspector on site.
What is the best way to prep a new garage floor for an epoxy coating?
Tell your contractor before the pour, because water vapor coming up through a slab can make epoxy and other moisture-sensitive coatings or adhesives fail. Knowing early changes how we prep, so the floor is ready for the coating from the start.
Do I need a licensed contractor to pour a garage floor in California?
In most cases, yes. The state's contractor licensing board describes a concrete contractor as one who forms, pours, places and finishes flat concrete work. California's exemption for unlicensed work stops at $1,000, and it applies only when the job needs no permit and the person doing it employs no one on the project.
