In this picture, you can see where a homeowner attempted to frame in interior walls and start finishing the basement. Unfortunately, the pink fiberglass insulation is not a viable solution because 1. it is exposed to a leaking wall and 2. this insulation when wet, molds.
The Healthy Spaces team removed the pink insulation and installed an r11 insulation board that will not mold and installed an interior waterproofing drainage system called Waterguard to keep the basement dry ALL the time so it can be finished.
