The BlockNet CMU single wythe flashing solution reliably protects CMU walls from water infiltration damage by enabling moisture to easily drain from the block cell interiors to the building exterior. Water in the block cells flows down the inside of the face of the cells through the BlockNet vertical mesh component and onto the horizontal stainless steel drainage section, which channels water out of the wall through the integrated horizontal drainage mesh element and drainage tabs.
