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 Does Concrete Need to Be for a Garage?
Most garages are made of concrete, and for good reason. Concrete is one of the most durable building materials available, and it can withstand a lot of wear and tear.
But how thick does concrete need to be for a garage? The thickness of concrete for a garage depends on a few factors, such as the climate, the weight of the vehicles that will be parked in the garage, and the size of the garage.
In general, however, concrete for a garage should be at least four inches thick. If you live in an area with a cold climate, you may need to pour concrete that is five or six inches thick.
This is because concrete can crack in cold weather if it is not thick enough. If you are going to park heavy vehicles in your garage, such as RVs or trucks, you will need to pour concrete that is at least six inches thick.
The heavier the vehicles, the thicker the concrete will need to be. Finally, the size of your garage will also affect the thickness of the concrete. If you have a small garage, you can get away with concrete that is four inches thick.
But if you have a large garage, you will need to pour concrete that is six or eight inches thick
