Which option lists the minimum embedment depth for wire wall ties in solid masonry units?

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

Answer: (B)

Embedment depth is how far the wire wall tie must penetrate into the solid masonry backing to develop the tie’s strength and transfer loads safely. For solid masonry units, the minimum depth required is 1-1/2 inches, providing enough material to resist pullout and shear. Depths smaller than this would not give proper anchorage, while a deeper depth isn’t required by the minimum specification.
