I'm looking to expand my buisness into concrete forming. We've been doing a lot of underpinning and foundation work lately including pouring a few addition and garage foundations with shop built 2x4 and plywood panels. They work good but there heaving and I want something to go in faster. I've been looking at advance concrete forms and I like the system. Most of the formers use them around here or a similiar system. What are the pro's and cons. Should I get a 4 bar, 5 bar or 6 bar system. What are the setup costs? What are you guys using. Cheers Kyle.
