Wall ties should be placed how far from the exposed edge of a masonry unit?

• A. 5/8 inch
• B. 3/8 inch
• C. 1/4 inch
• D. 1/2 inch

Answer: (A)

Wall ties must sit back from the exposed face enough to protect the brick edge and ensure solid mortar coverage around the tie. Setting the ties 5/8 inch from the exposed edge provides a safe clearance that aligns with typical mortar joint thickness and the brick’s face shell, allowing the tie to be fully embedded in mortar and resistant to spalling or edge crushing. If the ties are placed closer to the edge, the brick edge can be damaged and mortar coverage around the tie can be insufficient, weakening the bond. If they’re placed farther back, the tie may not engage properly with the veneer and could compromise attachment. Hence, the required distance is 5/8 inch.
