Intent 1:
To limit the probability of excessive lateral loading
on foundation walls or jacking pressures from adfreezing to foundation
walls, which could lead to:
- movement or cracking of foundation walls, or
- damage to a foundation's moisture-control elements.
Where foundations act as environmental separators, this
is to limit the probability of:
- condensation,
- precipitation 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 the temperature of interior
spaces, drafts, 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 environmental separators.
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.
