Intent 1:
To limit the probability that foundations will be
installed on loose soil which has a lower bearing capacity than expected,
which could lead to the undue subsidence of soil beneath foundations,
which could lead to excessive stress on foundations, which could lead
to structural damage to foundations and superstructures.
For foundation walls or elements supported by foundation
walls, 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, relative humidity, or water accumulation,
- the generation of pollutants from biological growth
or from materials that become unstable on wetting, or
- compromised integrity of foundation walls or elements
supported by foundation walls, 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.
