Nah, I hired those guys to finish the concrete for me. We're masons, not concrete finishers. I'm 6 weeks away from having power with the permits and scheduling with the power company to install new service. I bet you would like that truck. I will be purchasing one this year to add to some various demands we have. I'll have a roll off truck for less than $20k.
Floor is 5-6" thick with 5' piers under it for support. Concrete is 3500psi and 1/2" rebar 24" OC.
