The embedded depth requirement for wire wall ties in solid masonry units is at least how many inches?

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

Answer: (B)

Minimum embedment depth for a wire wall tie in solid masonry is 1-1/2 inches. This depth ensures there’s enough masonry around the tie to grip properly and to transfer lateral loads between wythes, reducing the risk of pull-out or failure under wind, seismic, or thermal movement. Embedding less would weaken the connection, while this 1-1/2 inch requirement strikes the right balance for reliable anchorage in solid masonry.
