Weep-Net™ is a free-draining polymer mesh designed to prevent mortar droppings and construction debris from clogging weep vents in masonry cavity walls. Installed at the base of the cavity, the mesh provides a clear pathway for water to reach the weeps while promoting airflow through the wall assembly.

Its dovetailed configuration helps prevent mortar from forming a continuous bridge across the cavity and provides the structural strength needed to support typical mortar loads. The polymer strands will not degrade within the cavity and are compatible with common cavity-wall components.
