If anyone is worried about a water source upstairs flooding your basement layout, use metal roofing for your basement ceiling. Also use the recommended screws that have the hex head with the rubber washer. Your drop down furring strips only need to be 4 feet apart and it can be ordered pre-cut to any length you want, so installation goes really fast. This was a great concern for myself since there was so much plumbing above. Now if we have a leak or over flow a sink or tub, the water will run in the ribs of the roofing to the walls. At the base of my walls into is a sump pump trench that leads to the sump pump chamber. I only wish I would have went with the black to get that museum look.
