ABSTRACT:
A hollow concrete building block is provided having physical characteristics which diverts water penetrating inside the block away from the interior of the building. The block comprises parallel interior and exterior walls and at least one transverse vertical web spanning between the walls to form a unitary block with an interior cavity. The webs have notches on the top and bottom surfaces which divert any infiltrating water into the cavities. The notches span the length of the top and bottom surfaces of the web. The apex of the top notch is proximate to the exterior wall of the block while the apex of the bottom notch is proximate to the interior wall. Once in the cavities, the water drops to the lowermost block where conventional flashing and weep holes convey the water to the exterior.
