Hey thanks for your input, ConcreteMasonry. I am also myself looking forward to remodeling a basement for some friends. They got flooding in their basement from an adjacent area under a sunroom installed off the main house, which houses a pool pump. They had a sump pump installed and that company cut a grroved channel all the way around that room to prevent futujre flooding into the main basement area, which they want to refinish for a children's playroom. That sunroom should have been constructed differently, but anyway we hope the main area should always be dry now, no matter what happens in that other room. BUt we would like to have more piece of mind; I scanned the terrain around the house to see if it was graded properly away from the house; would painting the cement walls with what you mentioned provide some protection in the occassional bad weatherstorm to come in the future? We are afraid of water from other places. do you have any othe advice? The cement foundation/basement wall is nearly entirely underground.
