What should be placed below the bottom of the sheathing and framing at the brick course?

• A. Drip edge
• B. Weep screed
• C. Flashing
• D. Cladding

Answer: (C)

The correct choice is flashing, which is a critical component in building construction, especially when dealing with walls that have brick cladding. Flashing is installed to prevent water from penetrating behind the brick veneer and into the sheathing and framing of the structure. By directing water that seeps through the brick or condensation away from critical structural elements, flashing helps protect against moisture damage, mold growth, and potential decay in the building materials. It is often placed below the brick course and extends out past the sheathing, guiding any water that comes down to the exterior surface. This provides a barrier that is essential in maintaining the longevity and integrity of the building. In contrast, the other options have different functions and applications. A drip edge is used primarily on roofing to direct water away from the fascia and prevent water from running underneath shingles or other roofing materials. Weep screed is a horizontal piece that allows moisture to escape from the wall system but does not serve the same protective function as flashing directly. Cladding refers to the exterior layer of materials (like brick) that offer aesthetic and weather-resistant properties, but it does not provide the water diversion necessary to protect the framing and sheathing.
