Intent 1:
To limit the probability of inadequate mortar density,
which could lead to the excessive shrinkage, cracking and premature
failure of mortar joints.
This is to limit the
probability of compromised structural integrity, which could lead
to:
- structural failure, or
- where masonry is exposed to precipitation, an inadequate
resistance to moisture transfer, which could lead to excessive water
ingress into or through assemblies, which could lead to the deterioration
of elements protected by the masonry, which could lead to compromised
structural integrity, which could lead to structural collapse.
This is to limit the probability of damage to the building.
