building on existing slab

[ziggyboy]

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 the pre fab garage,

Will the slab take the weight of the new brick garage with apex roof?

Cheers

I think the best advice would be to get an engineer to look at it. It should take the weight, but I don't think anyone is likely to give you a definitive yes or no.
