Basement Waterproofing - Around 7 inches of water in the flooded basement

On the right edge of this picture to can see that someone has stored extra panels of drywall which are now ruined. The main focus is the watermark on the concrete wall. Concrete blocks don't such up water as much as paper, drywall, or wood. Basically if you see a line in the wall, the water has been very close to that point.
