Not only does this give the wall a bright white clean look, it helps to direct water down the wall into the drain tile and creates a sealed waterproof system for the home. Waterproofing a home in this way means eliminates the need to dig up around the outside of the home to waterproof the area in an effective but typically more costly way.
