Garage Floors & Slabs

Concrete Garage Floor for Columbus, OH

Every winter your car parks a bucket's worth of salty slush on the garage floor and leaves it there to melt. Over the years that brine eats at the surface, and the floor starts to pit, flake and crack, usually worst right where the tires sit. Add a floor that never had much base under it, or one that settled because the clay got wet, and you end up with puddles that never drain and a crack that keeps growing. Replacing the floor fixes all of it at once.

A new garage floor means the old slab is broken out and hauled away, the ground firmed up, and a compacted gravel base put back. The new floor slopes slightly toward the overhead door so meltwater runs out instead of pooling. It is typically 4 inches thick for cars, heavier if you park a truck or keep a workshop. We also pour new slabs for detached garages and sheds, and once the floor has cured, a penetrating sealer makes the next round of salty winters a lot easier on it.

What's included

What goes into garage floors and slabs

  • 01

    Break-out and haul-away

    The old floor is cut free at the walls, broken up and carted off.

  • 02

    Base under the floor

    Firmed subgrade and compacted gravel so the new slab has even support.

  • 03

    Slope to the door

    A gentle fall so meltwater and wash water run out of the garage.

  • 04

    Right thickness

    Typically 4 inches for cars, more where trucks, lifts or heavy tool benches sit.

  • 05

    Smooth, sweepable finish

    A troweled surface that is easy to sweep and ready for a penetrating sealer after it cures.

  • 06

    New garage and shed slabs

    Slabs for new detached garages and sheds, with thickened edges where the walls bear.

How it works

Garage Floors & Slabs, step by step

  1. 1

    Empty and measure

    You clear the garage, and we check the door threshold and how water moves now.

  2. 2

    Break out

    The old floor is cut, broken up and removed, and the base is rebuilt and compacted.

  3. 3

    Pour and trowel

    Mesh or rebar goes in, then the slab is poured, sloped to the door and troweled smooth.

  4. 4

    Cure and seal

    Cars stay out for about a week, and the sealer goes on once the floor is ready.

Questions

Garage Floors & Slabs questions

Why is my garage floor flaking where the car parks?

Salt. The slush that drips off your car is loaded with road salt, and as it soaks in and freezes, it pops off the surface layer bit by bit. A penetrating sealer on a sound floor slows it down, and a badly scaled floor is best replaced.

What affects the cost of a new garage floor?

Size, thickness, how hard the old floor is to break out and haul, and how much base needs rebuilding. A one-car floor and a three-car floor with a workshop are very different jobs. The quote lays out each piece.

Do I have to empty the garage first?

Yes, completely, including shelves along the walls that could get dusty. For a brand-new detached garage slab, a building permit is usually involved, so check with your city or township, and 811 is called before any digging.

Can you match the new floor to the garage apron?

Yes. The new floor can meet the existing apron at a joint, at the same height, so nothing catches the tires. If the apron is cracked or tipped too, replacing both at once gives you one clean line at the door.

How long until I can park in the garage again?

Walk in after a day or two, but give it about a week before the car rolls back in, longer for a heavy truck. Concrete keeps getting stronger for about a month, so hold off on anything really heavy until then.
