Intent 1:
To limit the probability of discontinuity in the
head and bed mortar joints of solid masonry units, which could lead
to mortar joints of inadequate tensile and compressive strength.
This is to limit the probability of compromised structural
integrity, which could lead to:
- the 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.
