How thick should a garage slab be?
How thick should a garage slab be? 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. The standards are expressed in terms of “compressive strength,” which boils down to the amount of water used in the mix.
Do you need rebar in a garage slab?
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.
What’s better rebar or wire mesh?
Considering the support constraint, rebar is undoubtedly stronger than wire mesh. Several constructors consider rebar for domestic jobs. For thicker driveways and locations that involve greater traffic, rebar is always a good option to consider.
Is thicker concrete less likely to crack?
Why? Concrete of a thickness of less than 5″ is more prone to cracking, unfortunately this includes nearly all the poured slabs out there. Slabs 4″ thick are twice as resistant to fractures (heavy loads from above as well as lifting from below) than are 3″ slabs.
