Answer: 4-5 inches
Explanation: Code
Sams Construction LLC
Answer: 4-5 inches
Explanation: While our driveways are typically poured no less than 5” thick, we typically pour the concrete slab the same as the rest of the house, 4”-5” thick. Reason being, garages poured with the house have deeper footings that match the house as well as more steel to be able to withstand the weight of the house and to further minimize risk of settling/movement of your slab. Also, vehicles, that are parked inside of a garage, are typically smaller/lighter cars, while driveways have a much wider range of vehicles(some larger/heavier) that may drive on them. Such as a friend or family member just visiting or someone lost using your driveway to turn around.
Christian Campbell
Answer: 4-5 inches
Explanation: The standard slab thickness for a residential concrete garage floor is typically 4-6 inches. This range provides sufficient strength to support the weight of vehicles and withstand the additional stresses associated with garage use, such as the movement of cars, light trucks, and occasional heavy loads. A 4-inch slab is generally adequate for standard passenger vehicles, while a 6-inch slab is recommended for heavier vehicles or more frequent use. Proper reinforcement with rebar or wire mesh, along with well-prepared subgrade and proper drainage, ensures the garage floor's durability and longevity.
