Sealing the basement areas

[larryweikart]

Thanks for all the great input. I've decided to cut out the old and replace with an "insert" I just don't have enough old material left to do anything else.I will try to post pics along the way. If I were to weld the insert in, is it necessary to remove the battery cables or is using the disconnects enough to protect the ddec? I've also thought about using J-B Weld to secure the insert. Any thoughts on those 2 items before I get started? This project will keep me at our storage building, where I like to be anyway, tinkering!
