Basement Waterproofing - Checking the style of the wall

There are two types of basement walls, the monolithic and the standard. In a monolithic foundation the walls are built directly on top of the floor. In this type of construction the bottom seam of the wall is clearly visible, so the screwdriver in this photo wouldn't be in the crack. In a standard foundation the footer is poured, then the wall, and last the floor. It creates three separate pieces. Therefore, the bottom block on the wall is only partially seen. All of this tells the inspector which type of drainage system is appropriate for your basement.
