Construction Performance Guidelines
THICKNESS OF VERTICAL MORTAR JOINTS ARE NOT UNIFORM IN BRICK OR MASONRY UNITS
Vertical mortar joint thickness shall appear uniform when viewed from a distance of no less than 6 m, and shall be 10 mm with a tolerance of -5 mm to +10 mm in accordance with the Building Code.
One-Year - Work and Materials
Masonry with joints not meeting the acceptable condition shall be repaired.
Unintentional Dimensional variations of the courses are affected by the variations in the brick selected and the bond pattern. Non-uniform joints may be a feature of the wall and may be acceptable. Weep holes and/or vent holes are necessary in a masonry wall and shall not be blocked. This does not apply to randomly sized or designed masonry products such as (but not limited to) specialty brick products; tumbled or aged bricks, beveled-edged bricks or cultured stone or stone products.
