A masonry weep hole insert for placement into a weep hole in a masonry wall, the weep hole being defined by a space without mortar between two adjacent bricks on a lower level of bricks for draining moisture and venting air from an airspace behind said masonry wall. The insert is so dimensioned so that a portion of the insert substantially fills the space between the two adjacent bricks which form the weep hole, and so that another portion extends rearwardly and upwardly above the weep hole into the airspace behind the bricks. In one embodiment, the insert, made from a porous material which is permeable to air and water but not mortar, is designed so that at least a portion of the porous material remains exposed to the airspace behind the brick veneer even in the event that mortar or other debris happens to fall into the airspace. The porous material thereby provides a passageway for draining moisture and venting air which will not become inadvertently blocked by excess mortar or debris. In the second embodiment, the insert, made from any easily formed rigid material, includes longitudinal slots that act as a passageway to connect the airspace to the outside environment.

[ I claim:] [1.] A device insertable into a weep hole in a brick wall of a building and designed for use in preventing mortar and debris from blocking said weep hole said weep hole defined by a space without mortar between two adjacent bricks for draining moisture from an airspace behind said brick wall to the exterior of said building, said brick wall being composed of a plurality of substantially rectangular shaped bricks with each brick having a substantially uniform length L, height H and depth D, said weep hole having a height h substantially equivalent to the uniform height H of said bricks, a width w equivalent to the distance of the space without mortar between two adjacent bricks and a depth d substantially equivalent to the uniform depth D of said bricks, said insertable device comprising:a substantially flat L-shaped body having a first portion and a second portion;said first portion having a height h', width w' and depth d' substantially equivalent to the height h, width w and depth d, respectively, of said weep hole for placement of said first portion into said space, said first portion including a front wall surface exposed to the exterior of said buildings;said second portion extending rearwardly from said first portion into said airspace and extending upwardly above said height of said first portion, said second portion including first and second vertical surfaces exposed to the airspace behind the brick wall; and,said L-shaped body being made from a porous material, said porous material being permeable to air and water but impermeable to mortar, said body thereby comprising a multiplicity of air and water passageways extending from the vertical surfaces on the second portion to the exposed front wall surface on the first portion;whereby moisture from said airspace may drain through said porous material and out through said weep hole to the exterior of the building.
