Hi Everyone, Blg. Dept. total PITA - won't answer ANY questions. Anyone have actual experience retro fitting C. Block foundation to support 2nd Story Addition? My present foundation is 2 coarses hollow 6" CMU on a 7x12" NOT reinforced concrete footing. How can I make it support a 2nd story? I only need to do about 20 - 30' of it. (I would tear it out completely but those bstrds won't let me do it right). I have thought of carefully busting away most of the block except the back 1" then I could pour an 8" thick concrete wall against them. That doesn't fix the un-reinforced footer though. Maybe if the new wall was 10" thick I could sort of add an off-set footer next to the old with lots of re-bar? Should I blow out sections every 6' and put in a big footer for a wood post OR maybe a concrete sono-tube post? This is just so retarded. If the BO would spend 1/2 as much time helping me as he does saying "I'm not going to design it for you" I would be out of his hair. But he won't.......... Ideas anyone? Thanks.
