OK, I have an existing small Hardieplank and framing pump house that houses the pressure tank and softener system for our well water. The well is next to it, outside. It seems to be a quality little slab, about 6' x 6' The guy who built our place did good work, but he died in 2014 so I can't ask him if it has rebar in it or what.
I wonder if it is feasible to pour a larger slab directly adjacent, so the old slab is on the corner of the new slab. I guess I'd have to drill into the old slab sides and sink some rebar in there with cement, so the new slab could hold on to that rebar.
Just wondering if this idea is worth a crap, or if it stinks. The goal is to have a larger slab with an above ground water tank on it, under a metal building.
