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. |

DETAILED DESCRIPTION The present invention of a weep hole insert for masonry walls is comprised of a substantially L-shaped body in which one portion fits within the space between two adjacent bricks which define the weep hole, and a second portion which extends behind and above the weep hole in the airspace between the back side of the brick veneer and the interior wall.
In one embodiment, a porous weep hole insert for preventing mortar and debris from blocking a weep hole in a brick wall is disclosed.
The device is made from a porous material which will not absorb mortar, but will allow water and air to pass through it.
In a second embodiment, a molded weep hole insert for preventing mortar and debris from blocking a weep hole in a brick well is disclosed.
Rather than utilizing porous characteristics to allow the flow of air and water to flow through it, the second embodiment contains slots that extend transversely between the airspace and the exterior of the brick wall.
Moisture and air flow through the slots from the airspace to the exterior of the brick wall.
The two disclosed embodiments of the weep hole inserts presented herein are so dimensioned such that, even if mortar unintentionally falls behind the brick wall into the airspace, at least a portion of the device will remain exposed to the airspace and thereby provide a passage through either the porous material or the slots for draining water and moisture from the airspace behind the brick wall to the exterior of the building, and also to vent air between the airspace and outside atmosphere.
Consequently, the primary objects of the invention are to provide a device for preventing mortar and debris from blocking a weep hole in a brick wall; to provide a device which fits within a weep hole defined by a space between two adjacent bricks for draining moisture from behind the brick wall to the exterior of the building; to provide a device that is impermeable to mortar while permitting air and water to flow through it; and to provide a device which is small and easy to use during the construction of a brick wall in order to ensure that the wall provides proper drainage of moisture and venting of air
