Is a 4" - 5" patio slab thick enough to support a deck? The slab is 13'x29' and I want to center a 12'x27' deck over it. I plan to attach to the house and support the deck with four post. Do think the slab will support this? Thanks for any info.

I'm assuming it's a landscape deck under 30" high... if not you will need proper footings.

In most areas, at that lower height, you would be able to place the piers on the slab (if it's that thick), but check with your local building dept. first.

Check the 2 level wheelchair access deck on my deck site for some pictures of how to do that.

I put 2 rebars into the existing slab then used tube forms for the piers and the post bases into that. You have to be careful not to let the rebar touch the dirt below, so place a little hydraulic in there then the rebar that will stop the moisture mitigation.
