You generally won't find wash basins attached to the walls in modern basements. Also, the large cast iron pipes on the floor are a sign of older construction. These things present a slight challenge when designing a waterproofing system. This photo was from the day of the initial inspection. The stains on the concrete blocks let the inspector know that water has been high enough to leave a dirt ring behind. It is clear evidence of a major water problem.
