Mortar and debris collection device and system

DETAILED DESCRIPTION Accordingly, it is a principal objective of this invention to provide a mortar and debris collection device that can rest on the base of the wall cavity to cover and protect one or more weep holes preventing mortar or debris of any significant size from reaching a weep hole and thereby blocking the holes.
In addition, a related objective is to provide such a collection device which can be placed at different heights within the cavity without the use of any fixation device or special adaptation of the collection device.
Another objective is to provide a surface configuration for such a collection device which facilitates adequate dispersal of debris thereon to assure a water path remains to the collection device.
To the foregoing and other ends, the improved mortar and debris collection device of this invention comprises, in one aspect of the invention, a water-permeable body formed with circuitous (non-linear) pathways therethrough, which body can be readily placed within a cavity wall construction.
The inventive collection device can preferably be a non-absorbent water-permeable fibrous block having a porosity sufficient to permit water to pass therethrough, but insufficient to permit mortar or other debris of appreciable size to pass therethrough.
Another embodiment contemplates laterally extending projections formed on a supporting board which form the circuitous path.
The collection device is intended to be placed on the wall base within the cavity to cover up and block one or more weep hole openings from mortar and debris.
Water can migrate through the porous mass to a drain outlet, such as the weep holes, but mortar and debris cannot.
It is furthermore contemplated that the collection device may also be placed on existing supports, such as ties, along the walls.
No special fixation means for emplacement of the collection device is therefore required, and the collection device need not be specifically adapted for the particular application.
A preferred form of the collection device has upwardly extending protrusions, such as protrusions defining overhangs as well as steps, which serve to break up mortar and debris falling on top of the collection device
