Intent 1:
To limit the probability of excessive deviation
from the optimum mortar-joint thickness required to ensure continuous
support of masonry units while maintaining adequate mortar-to-masonry-unit
bond strength and adequate compressive strength of assemblies.
This is to limit the probability of compromised structural
integrity, which could lead to:
- structural failure of masonry construction,
- where masonry construction is part of an environmental
separator, the excessive deformation, displacement or failure of required
environmental separation elements, which could lead to deterioration,
which could lead to further compromised structural integrity, or
- in assemblies exposed to moisture or the exterior, damage
and deterioration, which could lead to further compromised structural
integrity.
This is to limit the probability of harm to persons.
