Construction Performance Guidelines
Article Number
Condition
ABOVE-GRADE MASONRY VENEER CLADDING (INCLUDING MORTAR) IS CRACKED
Acceptable Performance/Condition
Cracks resulting from normal shrinkage are acceptable; crack width in excess of 2 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 is excluded from the statutory warranty.
Action
Cracks in excess of the acceptable condition shall be repaired.
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. The colour/texture of repaired areas shall match the existing as closely as possible when dry. Variation in colour may be noticeable when wet.
