Howdy all,
Been a member here for 10 years or so, but usually get my answers from searching the archives. Still check in almost daily.....
Anyway, bought an old farm with a wood barn, center section is 15x40 with a REALLY rough slab poured in there probably 50 years ago. Didn't float or screed any of it, and I can't roll around toolboxes or anything else with wheels. Had several people mention pouring a new 4" slab over the old one, existing concrete "walls" are about 6" tall all the way around so we could pour right up to it.
Questions are, is it a good idea? Can't cut out the old one, and some of the old timers say I'll have to pin the new to the old. They say epoxy some 4" rebar "ells" 2" down in the old slab, then they will be up 2" into the new 4" slab.
Whatcha think? Any and all opinions appreciated!
Scott
