The lower portions of the Sheetrock have been removed because they have been damaged by water infiltration. Removing the sheetrock also allows us access to install the WaterGuard Drainage System as well as a 20-mil CleanSpace vapor barrier. The heavy-duty vapor barrier will help protect the basement from future outside moisture infiltration. It is mechanically fastened to the interior walls six to eight inches above outside grade, giving more protection to the basement.
