  BlockFlash® is an embeddable flashing pan for exterior single wythe CMU wall  

  systems. It collects moisture that infiltrates the wall and flows down the vertical cores and 

  diverts it to the exterior. BlockFlash® is a single wythe CMU flashing system that is

  useful at all flashing/weep hole locations including base of wall, above door and window

  openings, above bond beams, in parapet walls, basements and any other locations where

  flashing is necessary.
