hi!
I am planning a Pole Barn, part of which will be with a heated concrete floor. I will be asking questions to get the consensus expertise. Please stick to the topic, I will be asking several, and could easily miss your pearl of wisdom if you start crossing threads!
thanks!
Project Barn Q1, depth of the floating concrete

The shop/garage area will be on concrete, with vapor barrier and insulation below it..
How deep for a heavy truck?
does a metal concrete grid I see in the lumber yard work 4 x 12 feet?
Any special type of concrete?
