Garagenboden Betonleitfaden

Garage floors need 4–6 inch thick concrete at 3,500–4,000 PSI. Slope the floor ⅛–¼ inch per foot toward the garage door for drainage. Add control joints every 10–12 feet. Consider a vapor barrier on the sub-base if moisture is a concern. A standard 20×20 ft two-car garage at 5 inches needs about 6.2 cubic yards.
