Intent 1:
To limit the probability of insufficiently thick
concrete in foundation walls, which could lead to insufficient bearing
of supported walls or eccentric loads on the foundation, which could
lead to an inability to support gravity loads or lateral earth loads,
which could lead to concrete cracking.
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 accumulation,
- the generation of pollutants from biological growth
or from materials that become unstable on wetting, or
- compromised integrity of elements supported by foundations,
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.
