Hi everyone, im hoping for some of your advice, ive just moved into a new build house and the previous owner as put a 15ft long by 9ft wide slab down, Its a 4" thick slab with a sectional garage sitting on it, Ive dug round the edges to see if there are any footings and there is not, he put down 2 tonne of hardcore then wacker plated it down before pouring the slab down , there is no rebar in the slab He told me that the garage is approx 3 tonnnes in weight and the slab is holding fine, My question is, I want to build a brick in the same brick as the house in place as i dont like the look of t
