Intent 1:
To limit the probability of discontinuity in head
and bed mortar joints, 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.
