Garage Slabs
Garage Slab for Columbus, OH
A garage slab is a driveway that lives indoors, with three differences. It needs isolation joints wherever it meets a foundation wall, column or step, so it can move without cracking against them. It is usually finished smoother than a driveway so it sweeps clean, with a light broom near the door for traction. And its slope runs toward the overhead door, typically an eighth inch per foot, or to a floor drain if there is one. Thickness is commonly 4 inches, more for a car lift, a heavy truck or a workshop.
For a detached garage, the slab is often part of a foundation package: frost footings set roughly 32 inches down, under the local frost line, with the slab poured inside them or monolithically with a thickened edge, depending on the plans and local building rules. Inside an attached garage, the slab rests on backfill that has to be compacted in layers, because a floor poured on loose fill sinks along the walls. A two-car floor of about 24 by 24 feet is usually jointed into four roughly square panels.

Questions
Garage Slabs questions
Does a garage slab need to go below the frost line?
The slab itself does not; the footings around a detached garage do, at about 32 inches in central Ohio. A floating slab on compacted stone can work for small structures where local rules allow it, but frost heave on wet clay is the risk. The plans and the local building department decide which applies.
What goes into a garage slab quote?
Square footage, thickness, reinforcement, base depth, whether footings are included, the finish, and whether an old floor has to come out first. A detached garage slab with footings is a bigger scope than a floor inside an existing garage. Each part appears as its own line in the quote.
Does a new garage slab need a permit?
A slab for a new garage is usually part of a building permit, and the building department may inspect footings before the pour. Replacing a floor inside an existing garage may not need one, but rules vary between communities. 811 is called before any digging.
Should a garage slab have a vapor retarder?
For an attached garage, a polyethylene vapor retarder under the slab is common and cuts down on moisture coming up through the floor. Detached garages vary. It goes over the compacted stone, and the plans or building rules may call for it.
How thick should a slab be for a car lift?
Thicker than standard, often 5 to 6 inches or more under the lift posts with heavier steel, and the lift's installation instructions set the minimum. Decide on the lift location before the pour so that area can be built for it.
