Intent 1:

To limit the probability that frost-related soil movement beneath the adjacent slabs-on-ground will be transmitted, which could lead to excessive stresses, which could lead to the cracking of slabs-on-ground supporting attached buildings, which could lead to an inability to support vertical building loads.

This is to limit the probability of:

  • pollutant ingress from the exterior, including soil gas, combustion products from parking garages, or particulates,
  • compromised thermal performance of components intended to provide resistance to heat transfer,
  • condensation,
  • precipitation ingress, or
  • the ingress of moisture from the ground.

This is to limit the probability of:

  • an inadequate control of the temperature of interior spaces or water accumulation, or
  • deterioration, which could lead to compromised integrity of environmental separators or of elements protected by the 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.
