 So it's about water control on the outside of the home. But having said that, Ed, and this is what I'm trying to encourage you to do, having said that, if you've got a block foundation and the block is bowing, it's shifting, got a hole in it, you can see outside, that's a structural problem. You're really going to have to get a waterproofing company in there to really assess the situation or a structural engineer.
