A garage floor slab built from the base up

A garage floor is a concrete slab. Bay Area home slabs run four to six inches thick, and garages sit at the thicker end. Most people call us when the old floor has cracked, sunk or gone dusty. Your price turns on the size, the thickness, the steel and the base work your ground needs, and the written estimate spells it out.

I start with what you won't see. We dig out and pack the base, because much of Sonoma County's soil shrinks in long dry spells and can pull support away from slab edges. We cut control joints, grooves that give cracks a place to land, and we keep the floor separate from the walls and driveway so each moves on its own. The schedule turns on the weather, any permit and the cure.

Choices for your new garage floor

Get a quote
  1. Mesh-reinforced slab

    Wire mesh won't stop a slab from cracking, but it tends to keep cracks and joints from opening up, which suits cars and everyday garage use.

  2. Rebar-reinforced slab

    Rebar, steel bars tied in a grid inside the slab, makes sense for a heavy truck, a workshop full of tools or anything that parks in one spot.

  3. Broom or smooth finish

    A broom finish, fine lines dragged across the wet top, gives grip where rain tracks in, and for color or polish we also do decorative concrete.

  4. Hillside garage

    When the garage is cut into a slope, the dirt behind it needs holding back, so we can pour concrete retaining walls along with the floor.

Why homeowners hire us for garage floors

  • The owner at estimate and pour

    I come out to every estimate and I'm on site on pour day, so the person who planned your joints is there when the concrete goes in.

  • Years on crews before 2021

    I poured and finished on other people's crews for years before starting this business in Santa Rosa in 2021, and I've seen what skipped base work does later.

  • Licensed, insured, permits handled

    We're licensed and fully insured. The city requires a building permit unless the code exempts the work, so we check first, then apply and meet the inspector when one's needed.
