Not a Home Improvement Question?

Question

I am building a small work shop behind the house I want to use a concrete slab foundation. How thick should the slab be, what size re-bar and how do I space the re-bar. If it makes any different I am building in south Georgia near the coast. Is there a general rule of thumb? Respectfully Mr. Perron

Hi XXXXX

It depends on the size of your shop. You could build a modest sized shop on a 4" or 5" thick slab with just re-wire ( no re-bar) on good solid undisturbed soil. If you are building a larger structure you could pour a mono-lithic slab which is a 4" slab with a perimeter that's 1' thick ~2' wide. Re-bar would only be necessary if the soil was questionable. Questionable soil would be soil over any filled land or over peat. You need to remove any live soil (loam) whatever you do.
I'm assuming frost (in the ground) is not an issue in southern Georgia.

As long as this is a single story structure you should be fine with a 4" or 5" slab and re-wire.

Another expert has informed me that you are likely in a hurricane zone. So if you are pulling permits for this you would be subject to uplift requirements. This would entail anchoring the slab with piers at the corners tied into the slab pour and tie downs at the slab up through and including roof rafters,
