Building block transverse having asymmetric notches promote movement of water away from exterior wall

摘要

A hollow concrete building block includes transverse walls 13. The top and bottom edges of the transverse walls have asymmetric notches 26. The notches are in the form of an asymmetric "V". The apex 27 of the notch on the upper edge is adjacent one side wall 14 of the block, while the apex 29 of the notch on the bottom wall is adjacent the other wall. The blocks are arranged so that the apexes 27 are adjacent the outer wall of the structure formed by the blocks. Any water that enters the interior of the blocks is directed towards the apexes 27 and away from the interior wall of the block.
