Masonry Cavity Drainage Device
Keene Building Products
Keene Building Products is manufacturing a masonry cavity drainage device, the KeeneStone Cut, a three-dimensional, geometric patterned core with a high loft fabric laminated to one side. The highly compressible fabric is able to slightly compress to fill the cavity, allowing it to change thickness up to one-half inch to prevent any mortar blockage. This product is designed to catch and hold mortar dropping, while allowing moisture to pass through, and keep the weep holes open. The KeeneStone Cut is placed in a strip horizontally in a masonry cavity wall requiring no mechanical fasteners, and is manufactured to be 10 inches in height within the cavity.
