Construction Performance Guidelines
CUT BRICKS ARE OF DIFFERENT THICKNESS IN RELATION TO ONE ANOTHER
Cut bricks used in the same course shall appear uniform from a normal viewing position; the variance in thickness between two immediately adjacent bricks shall not exceed 8 mm.
One-Year - Work and Materials
Bricks not meeting the acceptable condition shall be repaired.
Even with proper coursing bricks will need to be cut to fit site conditions. It is common that cut bricks may vary in thickness. Uncut bricks may also vary in thickness depending on the style selected (e.g. tumbled bricks).
