This detail illustrates a base of wall condition for adhered brick veneer over concrete masonry (CMU) backing. A continuous air/moisture/vapor barrier (WRB) over the CMU includes a transition membrane at the control joint, and provides resistance to air and moisture. Continuous insulation provides thermal control to supplement the natural thermal mass of the masonry backing. Used as a rainscreen device, the drainage mat with protective filter fabric allows moisture to escape the wall via the corrosion resistant perforated weep screed at the horizontal termination. The WRB is applied over the weep screed in shingle fashion. A self-furring lath embedded in a scratch coat of mortar reinforces the veneer system. The veneer is adhered to the reinforced scratch coat with a bond coat of polymer modified mortar. The joints between the units may be pointed in using a masonry mortar.
