9.13.3.3.(1)

Objective

OH1 Indoor Conditions

Attribution

[F40-OH1.1]Applies where waterproofing materials are installed to control the infiltration of soil gas.

Intent

Intent 1:

To limit the probability that the performance of installed bituminous waterproofing materials will fall significantly below expectations.

This is to limit the probability of:

  • 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, relative humidity, or water ingress and 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 supported or protected by floors-on-ground, foundation walls or roofs of underground structures.

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.
