Every contractor in Arizona is obligated by law to follow the Arizona workmanship standards. Keep in mind that some manufacturers and code may differ, and these are minimum standards. The very bottom of quality standards.

The following are portions of the standards that are relevant to the roofing and waterproofing industry.

MASONRY

Masonry walls should be straight, plumb and level, with uniform mortar joints and proper grout and vertical horizontal reinforcement. CMU will vary in texture and color; therefore, care should be used in the selection of the material. Slump block will absorb moisture and should be sealed to prevent leaks through walls and damage in freeze thaw zones.

1. PD Crooked, out-of-plumb, out-of-level masonry walls.

AT 1/4" out of plumb, 1/2" in total length of wall out of level not to exceed 1/4" in
