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

The guideline for placing wall ties in masonry construction specifies a distance of 1/2 inch from the edge of a masonry unit. This spacing is important because it helps to ensure that the ties are embedded adequately in the mortar joint without compromising the integrity of the masonry units. A distance of 1/2 inch provides the necessary support for the wall ties, allowing for adequate load transfer and structural stability.

Placing ties too close to the edge could lead to cracking or failure of the masonry unit, as the edge is more vulnerable to stress. Conversely, placing them too far from the edge may reduce their effectiveness in anchoring the wall properly, resulting in inadequate support for the wall system. Following this specification ensures compliance with construction standards and improves the durability of the masonry work.
