Intent 1:

To limit the probability of excessively porous mortar between concrete blocks, which could lead to an inadequate resistance to water.

Where elements support or are part of an environmental separator, this is to limit the probability of:

  • the ingress of surface water or rainwater, 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
  • deterioration, which could lead to compromised integrity of foundation walls or elements supported or protected by foundation walls.

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.
