Garage floor concrete problems we fix

At Riverside Concrete Company, we find most garage floor trouble in Riverside starts in the ground underneath, and catching it early keeps a crack from becoming a new floor.

  • Cracks across the floor

    Wandering cracks usually mean the ground shifted or nobody cut control joints, the grooves that give concrete a planned place to crack. We handle both on a new floor.

  • A corner that's sinking

    A floor that drops or tilts usually sits on dirt that was raked level instead of dug out and packed. We dig to firm soil and compact it first.

  • Chipping or a dusty top

    A top that flakes or dusts often came from a midday pour that dried too fast. We plan when we pour and keep it moist while it cures and hardens.

  • Water pooling inside

    Puddles on the floor or water running toward the walls mean the slab wasn't sloped right. We check where water goes and set the floor to drain out the door.

Fix the floor or pour a new one?

I'll tell you on site which one your floor needs, because the ground underneath, the size and what the garage will hold decide the job, its price and how long it takes.

  • A repair is enough when:

    • Cracks are thin and few
    • The floor hasn't sunk or tilted
    • Both sides of a crack sit level
    • Water still drains out the door
    • You're parking the same cars as before

  • A new slab is better when:

    • A section has sunk or tilted
    • Cracks keep widening or shifting
    • Water pools or runs toward the walls
    • The top is chipping all over
    • You're adding an RV, a lift or heavy tools

  3. Your written estimate

    You get it in writing, with what's in it and what isn't spelled out plainly, and we agree on who handles anything the city requires.

  4. Ground work and forms

    Our crew digs out the subgrade, the ground the slab sits on, packs it firm and sets the forms and steel the load calls for.

  5. Pour day and walk-through

    Our lead finisher runs the crew, I'm on site for the pour, and we walk the finished floor with you before we clean up and pack out.

What our garage floor concrete work includes

  1. Layout and heights

    We mark the edges and set heights so the new floor meets the driveway and the house door evenly.

  2. Digging to firm ground

    We dig out loose fill down to firm subgrade rather than raking dirt level and pouring over it.

  3. A compacted base

    We pack the base in even layers so the whole slab rests on ground that's firm from edge to edge.

  4. Forms and rebar

    We set the forms and place rebar, the steel bars that tie the slab together, sized for what the garage will hold.

  5. Pour and finish

    We place and level the concrete, then trowel it smooth or give it a broom finish, a light texture for grip.

  6. Control joints and clean-up

    We cut the control joints soon after the pour, then haul off our waste and leave your garage swept.

What sets the price of a garage floor?

Size and what the floor has to hold set most of the price, because an RV, a lift or heavy tools call for a thicker slab with more steel. The ground work counts too, and if the garage is cut into a slope, a concrete retaining wall may be part of the job. Color or a pattern from our decorative concrete work adds to it. The schedule turns on the ground work, city steps and the cure.

When money's tight, the base is the first thing people want to trim, because nobody sees it once the concrete is down. I'd rather you skip the color than skimp underneath, since a finish can be added later but bad ground under a slab means starting over.

Why Riverside homeowners trust us with garage floors

I learned concrete on a city public works crew, pouring sidewalks, curbs and ramps to a written spec with an inspector watching, and I started this business in Riverside in 2013 to bring that same care to homes. We're best known for driveways, patios and other flatwork, the flat slabs that have to sit right and shed water.

On a garage, I ask what it'll hold, like an RV, a lift or heavy tools, before I price it, because that changes the slab. Then we put as much care into the ground underneath as into the concrete on top, and if a specialist would serve you better, I'll say so. Please call (951) 631-9520 or use the form when you're ready.

Questions about garage floors in Riverside

How much does a concrete garage floor cost in Riverside?

A concrete slab in Riverside usually costs about $7 to $14 per square foot, which is the going rate for slab work in the area, not a quote from us. Reinforced concrete runs a little more per square foot than a plain pad, and staining or stamping falls outside that range. Your written estimate spells out what's in your floor's price and what isn't.

How long before I can walk or park on a new garage floor?

You can usually walk on a new slab within 48 hours, and it takes about a month to fully cure. One guide suggests waiting a week before heavier loads, so plan on about a week with heavy loads kept off the new floor. We'll talk through your timing before the pour so the garage isn't tied up by surprise.

Do I need a permit for a new garage floor in Riverside?

Check with the city before we pour, because Riverside's building official issues permits for most construction and the city's exempt list names driveways and sidewalks, not garage floors. You apply at the Permit Services counter in the One Stop Shop, and some projects need drawings for plan check review. Many city permits can go to the owner, the owner's agent or a licensed contractor, so we agree with you up front on who applies, and when it's us, we bring our license paperwork.

Does an RV or a car lift change how a garage slab is built?

Yes, a garage slab for RV storage or heavy workshop equipment is typically built thicker, with reinforcement, beyond the basic code minimum. That use shapes the whole slab design, so it needs to be settled before the pour, not after. One guide recommends a structural engineer for a slab under a vehicle lift or large stored loads, and I'll tell you plainly if I think yours calls for one.

How do I check a concrete contractor's license in California?

Look the contractor up with the California Contractors State Licensing Board, since the state licenses contractors for flat concrete work. An unlicensed worker can only take small jobs within the state's $1,000 limit, and only when the work needs no permit and they employ no one. In Riverside, a contractor also needs a current City of Riverside business license. We're licensed and fully insured, and happy to show you our paperwork.

What causes a new concrete garage floor to crack?

Uneven ground is the usual cause, because soil that isn't evenly packed settles under the slab and cracks it no matter how thick or strong the concrete is. That's why the ground work deserves as much attention in a quote as the concrete itself. Wire mesh adds little strength to a thin slab, but it holds crack edges together so a crack stays narrower.
