Intent 1:
To limit the probability of inadequate crack control,
which could lead to random cracking of cast-in-place and concrete
block foundation walls due to shrinkage or soil movement.
Where elements support or are part of an environmental separator,
this is to limit the probability of:
- the ingress of water or 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 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 elements 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.
