In solid masonry construction, wire wall ties must be embedded to a minimum of how many inches?

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

Answer: (C)

Wire wall ties need enough depth in masonry to develop a solid bond and transfer loads without pulling out. In solid masonry, the minimum embedment depth for these ties is 1-1/2 inches, which provides sufficient mortar contact and anchorage. Embedment is measured into the masonry from the wall’s face, so anything less than 1-1/2 inches risks inadequate grip and reduced tie performance. While deeper embedment (for example, 1-3/4 inches) would also work, the smallest acceptable depth per code/standard is 1-1/2 inches.
