01.070.0301 Base of wall | Adhered brick veneer, CMU backing

International Masonry Institute
This detail illustrates a base conditions at an adhered veneer wall with CMU backing. A vertical control joint in the CMU is treated with transition membrane which engages with the air/moisture/vapor barrier in the field of the wall providing continuous resistance to air and moisture. Continuous insulation offers excellent thermal control, and a drainage mat collects moisture that may penetrate the veneer and diverts it out through the perforated weep screed below the veneer. Self-furring lath is screwed through the drainage and insulation into the CMU with approved fasteners at required spacing and is embedded in the scratch coat. Casing beads engage with the lath to form terminations and brick expansion joints as required. The thin brick veneer is adhered to the scratch coat with a modified bonding mortar per design.
