Using our FlexiSpan Wall Crack Repair System, we have used a sealant that is placed in the crack. The crack is then covered with the FlexiSpan Foam Drain Strip and covered with a sealant overlay. After that, we add a sheet of BrightWall to cover the crack and give that area a cleaner look. The BrightWall panels can be placed around the entire basement if the homeowner would like a fresh, clean look throughout.
