Application

Intent
Intent 1: 
To limit the probability of inappropriate backfill material, which could lead to point loads being applied to foundation walls by boulders in the backfill under lateral soil pressure, which could lead to:
  • the cracking of foundation walls, or
  • damage to a foundation's moisture-control elements.
Where foundations act as environmental separators, 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, drafts, 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 environmental separators.
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.
