In residential masonry cavity walls, mortar collection above the flashing and weep hole levels is vital for proper masonry cavity wall performance and to prevent water damage.  HouseNet 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 HouseNet for mortar suspension and collection, residential cavity walls perform the way they’re designed and walls stay dry and trouble-free.
