ABSTRACT:
A flashing and drainage system for use in cavity wall construction, including a flashing member is sized and shaped to be received within a cavity of the wall and over a base member. The flashing member includes a lower flashing portion, which is oriented generally horizontally when atop a foundation portion of the wall, and an upper flashing portion, which is oriented generally vertically within the cavity of the wall. A plurality of weep tabs are positioned on the lower flashing portion and spaced apart to correspond to weep holes formed through the wall and a plurality of porous bodies are positioned on the upper flashing portion. Each of the plurality of porous bodies have a porosity sufficient to permit water to pass therethrough but substantially insufficient to permit mortar and debris to pass therethrough, each of the plurality of porous bodies being positioned to protect a corresponding one of the plurality of weep tabs.
