Hey Fellas, I am putting an addition onto my garage. Five courses of 8'' block, My question is; what are the demensions of the footing? Do I need rebar?and where. I live in NJ. I believe the depth of the footing is 36'' at the bottom of the footer. Any help would be appreciated! Thanks, Lou. Edited 5/4/2007 9:04 pm ET by loucarabasi
