Intent 1:
To limit the probability of excessively porous mortar
between concrete blocks, which could lead to an inadequate resistance
to water.
Where elements support or are part of
an environmental separator, this is to limit the probability of:
- the ingress of surface water or rainwater, 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 accumulation,
- the generation of pollutants from biological growth
or from materials that become unstable on wetting, or
- deterioration, which could lead to compromised integrity
of foundation walls or elements supported or protected by foundation
walls.
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.
