Moisture Drainage - BlockNet®

BlockNet® is the perfect flashing system for exterior single wythe C.M.U. walls designed with a visible stainless steel drip edge. Stainless steel drainage sections collect moisture and channel it to the exterior of the building through the integrated drainage mesh weep tabs. 7" x 7" vertical mesh elements install in the C.M.U. block cells above the drainage sections to allow moisture to flow around mortar droppings to the weep tabs.

Used wherever flashing is necessary, including at the base of the wall, in parapet walls and over wall openings and bond beams. It may be used in reinforced or unreinforced 8", 10", and 12" walls, and in unreinforced 6" walls. It may be used in new construction and is also ideal for restoration or rehab projects.
