Intent 1:
To limit the probability that the use of inappropriate
or substandard mortar will lead to cracking at mortar joints and inadequate
bonding to masonry units, which could lead to the inadequate performance
or premature failure of concrete block foundation walls under expected
environmental or structural loads.
Where elements
support or are part of an environmental separator, this is to limit
the probability of:
- condensation,
- rainwater ingress,
- the ingress of moisture from the ground, or
- compromised thermal performance of components intended
to provide resistance to heat transfer.
This is to limit the probability of:
- an inadequate control of temperatures of interior spaces,
relative humidity, or water ingress and accumulation,
- the generation of pollutants from biological growth
or from materials that become unstable on wetting, or
- compromised integrity of the environmental separator,
which could lead to the deterioration of building elements.
This is to limit the probability of:
- negative effects on the air quality of indoor spaces,
- the inadequate thermal comfort of persons, and
- contact with moisture.
This is to limit the probability of harm to persons.
