Intent 1:
To limit the probability that the vertical reinforcement
will be interrupted at critical transition points or that it will
be insufficiently embedded to develop a bond with the concrete, which
could lead to an inability to support transverse or vertical loads,
which could lead to the cracking or displacement of foundation walls.
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.
