Attribution
[F61-OH1.1,OH1.2,OH1.3]
[F40-OH1.1] Applies where waterproofing materials are installed to control the infiltration of soil gas.
Application
Application 1: 
Method of application of bituminous materials that are installed to provide waterproofing for:
  • floors-on-ground that are subject to hydrostatic pressure,
  • walls below ground level that are subject to hydrostatic pressure, where the finished ground level outside is higher than the ground level inside, and
  • roofs of underground structures.
This applies to buildings to which Part 9 applies [see Sentence 1.3.3.3.(1) of Division A for application of Part 9].

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.
