A mesh device for retaining mortar and other debris within a mortar-cavity-wall so as to prevent such material from falling in front of and hence blocking the "weep holes" placed at the bottom of such a wall to permit the egress of moisture condensate that forms within this type of wall. The device of the present invention is a rectangle of thin, openly woven mesh of basically a planar shape but with "bumps" distributed across the plane in such manner that when the device is placed upright within the cavity the bumps form barriers to the dropping of mortar and other debris. The bumps themselves, being made of the same material as the rest of the device, are fully permeable to moisture working its way down the cavity. Furthermore, there is an offset of the bumps in one row from those in the next so as to further reduce the possibility of a blockage occurring, say by debris accumulated on the bumps. Finally, the bumps on one side of the planar surface are matched by "dimples" on the other side. This permits nesting of the individual devices, thus reducing the space that the units take up during transportation and storage. |

DETAILED DESCRIPTION The mesh device of the present invention is inexpensive to manufacture, requires no installation steps beyond dropping it into the masonry wall cavity, is of such a shape that a smaller mass of mesh can accomplish the same debris-blocking task of earlier "full-width" mesh blocks.
Furthermore, it is of a nestable shape so that an unlimited number of the individual mesh units may be nested together for shipping and storage.
The device of the present invention is made up of thin sheets of non-degradable, non-absorbent fiber mesh screen.
The essence of the invention is the manner in which these sheets are shaped.
Basically planar, the sheets have arrayed over their entire surface blisters that create convex nodes on one side of the sheet and concave dimples on the other side.
Viewed from the node-side, one of these sheets looks like a plane with an array of isolated mounds.
The device of the present invention utilizes a mesh density--defined in terms of the average space between fibers--that is sufficiently large to permit the free passage of moisture condensate and air while being sufficiently small to prevent penetration by falling mortar and other construction debris large that could obstruct the cavity weep holes.
The fiber-mesh screen is fabricated into sheets preferably 9 to 18 inches wide and in lengths to meet standard construction needs--e.
g.
, four and eight feet.
On a given sheet, the nodes all extend to the same distance "above" the plane of the sheet, the distance being chosen to equal the depth of the air-space cavity in which the screen sheets are to be used.
Preferably, the nodes are molded so as to be integral impressions in the fiber-mesh sheet; thus, an advantage of the present invention is ease of fabrication.
The described nodes are made large enough and structurally strong enough to effectively block and collect drops of extruded wet mortar and of other construction debris large enough obstruct a cavity wall weep hole.
They are arranged in a pattern such that, with the sheet installed vertically within a masonry cavity wall, debris falling within the cavity where the sheet is installed must encounter at least one node
