Garage Foundations
Garage Foundation for Columbus, OH
A garage looks simple until you have to set it on Central Ohio ground. It still needs to stay put through winters that freeze and thaw all season, and its slab has to carry cars, trucks and whatever ends up on the workbench. We build garage foundations for detached garages, attached garages on new homes and garage workshops around Columbus. Depending on the plans and the local building department, that means footings below the frost line with a short frost wall and the slab inside, or a slab with thickened edges.
The details are where garages go right or wrong. The frost wall top has to be level so the framer's sill sits flat, and anchor bolts land where the plans put them, with the door openings left clear. The slab gets a compacted gravel base and reinforcement, and it falls toward the big door so meltwater runs out. The apron at the door is poured thick enough for vehicles and joined to the slab at a joint. Get those right and the framer has a clean start.

Questions
Garage Foundations questions
Why does a garage need footings below the frost line?
Because frost heave lifts anything resting on soil that freezes. In Central Ohio the ground can freeze about 32 inches down, so footings that stop short can rise and drop each winter, cracking the slab and racking the walls. Some building departments allow a thickened-edge slab for smaller detached garages, so check what yours requires.
What sets the price of a garage foundation?
Size, the foundation type on the plans, footing and wall dimensions, slab thickness and reinforcement, the apron and how easy it is to get a truck to the spot. A detached garage at the back of a lot may need a pump. The quote lists each part.
Do I need a permit for a detached garage foundation?
Almost always. It rides on the garage's building permit, issued by the local city, village or township, and many HOAs ask to see garage plans too. The footing inspection happens before the pour. 811 is called before any digging.
How thick should a garage slab be?
Typically 4 inches for cars on a compacted gravel base, more for heavy trucks, lifts or equipment, and whatever the plans specify. Thickened edges or a frost wall carry the walls themselves.
Can the slab be poured at the same time as the footings?
Sometimes. A thickened-edge slab is poured in one go. With footings and frost walls, the slab usually comes after the walls and any inspections, once the gravel inside is compacted.
