Intent 1:
To limit the probability of discontinuity in mortar
joints at either interior or exterior faces of hollow masonry units,
which could lead to inadequate tensile and compressive strength of
mortar joints.
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.
