We had to fix a huge mess before we could pour concrete in this pole barn.

There was some serious problems with the way the builder of this pole barn prepared the sub grade. Normally all the clay dirt and stumps would be boxed out and removed and replaced with gravel prior to the barn being built but not on this one. They just put a little gravel over the stumps and clay dirt and built the barn. Good thing we dug down and caught this or his floor would have froze underneith and heaved. The mushrooms growing in the inside of the barn gave it away though. LOL
