Intent 1:

To limit the probability that the vertical bar reinforcement will not be adequately encased and bonded to the concrete, or of excessive eccentricity of load resistance, 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.
