Mortar dropping collection device slims down

39 Wall 400Developer of moisture management solutions for masonry walls has added a 0.4-in.-thick size to its WallDefender line. Originally available in 1- and 2-in. thicknesses, the product helps curtail moisture damage to masonry cavity walls by preventing mortar droppings from blocking weep holes. It suspends droppings above flashing on two levels of its trapezoidal-shaped, open-weave mesh, while allowing water to flow through the mesh and exit the cavity.

The new WallDefender size suits smaller wall cavities typical in residential and light commercial construction. Clean and non-toxic, it will not oxidize or react with common materials. Affords moisture management throughout the life of the wall. — Mortar Net Solutions, Burns Harbor, Ind.;
