My mother in law is in the process of converting a summer room in Fla. into a bedroom. Part of the renovation includes a new slab on top of the old slab. The new slab will be 17’x17′ and between 6 to 8 inches deep with 6×6 welded wire mesh. It’s being poured into the block shell of the old room, using the block walls as the outer forms. I’m worried about possible sinkage as well as cracking, or possible even expansion pushing the block walls out. It seems like a heck of a lot of weight as well as a large surface with no room for expansion and contraction. The contractor says because it’s in a moderate climate (Florida), it won’t be a problem. Am I just being paranoid? Any thoughts on this would be greatly appreciated. Thanks, Brian
