How thick should a monolithic slab be?
How thick should a monolithic slab be?
12 to 18 inches thick
A familiar monolithic slab foundation is 12 to 18 inches thick at the footing and 4 to 6 thick for the slab. Proper site preparation and reinforcement of the concrete using rebar and wire are required to construct a monolithic foundation.
How thick does a concrete slab need to be for garage?
The concrete slab should be four inches thick at least; it needs to be thicker if heavy equipment will rest on it. Building codes offer requirements for the concrete mix, which vary by region.
How thick does a garage foundation need to be?
Choosing The Right Foundation Mixture The garage foundation should be a minimum of four inches thick when placed on good soil. It may need to be thicker if the garage will be home to unusually heavy equipment.
How thick do you pour a garage floor?
Thickness of Garage Floor Slab
- Light Loads – For one to two light cars or trucks, the concrete should be at least four inches thick.
- Medium Loads – If the garage is used for average-sized vehicles and/or medium to heavy trucks, the concrete needs to be six inches thick.
Do monolithic slabs crack?
They tend to crack along the thickened perimeter when significant weight loads are used, like block exterior walls.
How large can a monolithic slab be?
Some specifers limit the single-placement area of concrete slabs-on-ground to 2,000 to 5,000 square feet, but specifications sometimes place a very stringent single-placement limit of 900 square feet (a 30×30-foot panel).
Does a garage slab need rebar?
A garage slab or the garage concrete floor does not need rebars, provided it is 4” or less in thickness. Other forms of concrete reinforcement will however reduce cracks. Rebar is certainly required if the garage slab is 6” or thicker. This is the short & sweet answer.
Does a garage slab need footings?
A footing will almost always be required when building a garage with a second floor. Generally, you pour perimeter footings to support the weight of the framing and roof. The footing is there solely to support the structure. You then pour the garage slab separately.
What kind of foundation do I need for a garage?

Does a garage floor need rebar?
How long does a monolithic slab last?
DURABILITY. Despite the simplicity, a monolithic slab foundation will last around 50 years if properly constructed. Because of the absence of complex elements, there’s little to go wrong with the slab itself.
