Back5.8.2.3.(2)

ATTRIBUTION:

Functional Statement:

F61

To resist the ingress of precipitation, water or moisture from the exterior or from the ground.

Objective:

OH1.1, OH1.2, OH1.3

 

APPLICATION:

Installation of materials and components to provide the required resistance to moisture transfer from the ground into or through building assemblies, and through interfaces between assemblies, where:
  • such installation is within the application of the standards listed, and
  • such assemblies:
    • are constructed of cast-in-place concrete,
    • have a drainage layer installed between the assembly and the soil to reduce moisture loading, and
    • are not exposed to hydrostatic pressure.
This applies to building materials, components or assemblies and their interfaces described in Sentence 5.1.2.1.(1) that are installed in buildings to which Part 5 applies [see Sentence 1.3.3.2.(1) of Division A for application of Part 5].

INTENT:

To limit the probability that the performance of the installed material, with respect to resistance to moisture transfer, will fall significantly below expectations, which could lead to moisture ingress from the ground.
This is to limit the probability of:
  • the 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 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.

To limit the probability that the performance of the installed material, with respect to resistance to moisture transfer, will fall significantly below expectations, which could lead to moisture ingress from the ground.
This is to limit the probability of deterioration, which could lead to compromised structural integrity of the separators or of elements supported or protected by the separators, which could lead to structural failure, which could lead to harm to persons.
