Yeah, my logic is all messed up on this problem you present. I'd also have to question what is needed for water proofing, obviously concrete will have to be, what about the lego block pour? Same thing, or does it require a tar and a wrap of sorts?

I have no real data to help you here.

Just curious more than anything. We did a traditional pour here about 10 years ago. Seemed like a hassle, a lot of labor with forms, more so than some foam blocks would be.

a. setup blocks, pour, walk away.
b. setup forms, install wire, pour, wait, remove forms.
