Intent 1:
To limit the probability of:
- the ingress of water into basements, or
- soil erosion, which could lead to negative effects on
grading near foundations, which could lead to the flow of surface
runoff toward foundations.
This is to limit the probability of
overloading dampproofing or drainage systems, which could lead to:
- precipitation or meltwater ingress, or
- compromised thermal performance of components intended
to provide resistance to heat transfer.
This is to limit the probability of:
- an inadequate control of relative humidity, temperatures
of interior spaces 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 roofs or assemblies protected by roofs.
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.
