Since the block and the stem wall are flush with one another and the surface bond is applied over that joint for a waterproof and airtight seal. There is literally no structural place for either termites or pests to enter the home. The code requires weepscreeds because they allow for easy detection where termites usually enter the home.
Termites are extremely prevalent in the Valley and unfortunately are here to stay.
Historically, chemical treatment has kept termites under control. Utilizing our insulated masonry system practically eliminates the need for chemical termite treatment after initial code mandated pre-slab application. The requirement of weepscreeds cause a protrusion of foam and stucco usually 1 to 2 inches out from the stem wall. This area becomes an excellent nesting area for a variety of insects and spiders. By eliminating this nesting area, you greatly reduce the potential for pest infiltration into the building.
