For solid masonry units, what is the minimum embedment depth for a wire wall tie embedded in mortar?

• A. 1 inch
• B. 1-1/4 inch
• C. 1-1/2 inch
• D. 1-3/4 inch

Answer: (C)

The main idea is ensuring the wire wall tie is anchored deep enough in the mortar to develop its strength and transfer loads reliably. For solid masonry units, the minimum embedment into the mortar is 1-1/2 inches. This depth provides enough mortar bond length to resist pull-out and shear forces; embedding less—like 1 inch or 1-1/4 inch—weakens the connection and increases the risk of failure. Embedding 1-3/4 inch would meet and exceed the minimum, but the question asks for the minimum, which is 1-1/2 inches.
