Here we have a window that is partially sub-subterranean as you can see by looking at the lower right side of the window. This window is an entry point for outside air and water and will be included in the basement waterproofing. When we waterproof your basement, they do not do all four walls floor to ceiling if that is not what is needed, they only treat the infected areas which will save you a lot of money. In this house's particular case the all four walls were problematic and floor to ceiling was underground so the entire basement was treated.
