Intent

Intent 1:

To limit the probability that soil movement resulting from freezing of the soil will lead to the heaving or subsidence of floors-on-ground, which could lead to:

  • the failure of floors-on-ground, or
  • the compromised structural integrity of floors-on-ground, which could lead to the ingress of moisture from the ground, which could lead to the deterioration of building elements.

This is to limit the probability of:

  • precipitation ingress,
  • condensation, or
  • the ingress of moisture from the ground.

This is to limit the probability of:

  • an inadequate control of 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 elements protected by floors-on-ground.

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.
