Over 20 Years of installations.  Thousands of walls.  
Not a single wall failure.

MortarNet helps prevent moisture damage to masonry cavity walls by preventing mortar droppings from blocking the weep holes and by providing hundreds of clear drainage pathways that allow moisture to flow to the weeps.  Its open mesh also allows air movement to help equalize pressure and dry the cavity.
