WallDefender™ | Helps Keep Cavity Walls Dry and Flashings Functioning Properly

Mortar dropping device that helps prevent mortar droppings from blocking the weeps.

In masonry cavity walls, mortar collection above the flashing and weep hole levels is vital for proper masonry wall performance and to prevent water damage.  WallDefender suspends mortar droppings above the flashing and weeps so they stay clear and unobstructed.  Its 90% open mesh allows moisture to flow to the weeps and air to move within the cavity to promote drying.  By using WallDefender for mortar suspension and collection, cavity walls perform the way they're designed and walls stay dry and trouble-free.
