Patent attributes
A system for venting moisture from wall and building structures, especially masonry walls constructed from masonry elements such as of brick, block, stone, faux stone or the like, without weakening the wall or building structure, utilizes open matrix weep vent members that are fabricated, for example from a mass of intertwined and intertangled polymeric filaments that are bonded at a plurality of intersections thereby to form one-piece or unit-handled weep vent members that preferably are inserted in place of mortar at spaced locations along horizontally extending mortar joints between rows of bricks, blocks or other masonry wall elements. Weep vent members that embody the present invention have wider portions at their rearward or intake end regions, and narrower portions at their forward or discharge end regions, with a preferred form characterized by a generally trapezoidal shape that helps to retain the weep vent members in their associated mortar joints, and that provide a funnel-like ducting of moisture from their relatively wider rear end regions toward their relatively narrower forward end regions.
