For most domestic garages, a six-inch slab of concrete will be sufficient. It is only when a space will see constant traffic from much heavier vehicles that a concrete slab of more than six inches would be needed.
How Thick Should a Concrete Slab Be for a Garage?
Having a garage is a great way to store your belongings, park your car, or even use as a workshop. When constructing a garage, one of the most important components of the structure is the floor.
A concrete slab makes for a durable and reliable option for a garage floor, but how thick should a concrete slab be for a garage? A concrete slab is a flat layer of concrete that is laid on the ground to give a level surface.
Concrete slabs are usually between two and four inches thick, although the exact thickness depends on the purpose of the slab and the soil beneath it. When it comes to a garage, the concrete slab should be at least four inches thick.
Four inches is the minimum thickness for a concrete slab that will be supporting a car. This ensures that the weight of the car is evenly distributed and that the slab will not crack or break when the car drives over it.
The thickness of the slab should also be increased if the garage will be used for storage, as the additional weight of the items stored could cause the slab to crack or break.
In addition to the thickness of the concrete slab, the type of concrete used is also important. Ideally, the concrete should be a mix of Portland cement and aggregate
