Above-Grade Masonry Wall Or Veneer Cladding (Including Mortar) Is Cracked

Acceptable Performance/Condition
Cracks resulting from normal shrinkage are acceptable; crack width in excess of 3 mm is not acceptable.

Warranty
One -Year Work and Materials
Cracks resulting from normal shrinkage of materials caused by drying after construction or normal wear and tear are excluded from the warranty.

Remarks
Shrinkage during curing of the masonry is natural. Also, regular outdoor temperature fluctuations cause masonry cladding to expand and contract. The resulting thermal stress can also cause cracking; this is considered normal wear and tear.
