Intent 1:
To limit the probability of:
- a loss of continuity between drain tiles, or
- the inappropriate placement of drain tiles or pipes.
This is to limit the probability of:
- the excessive settlement of drain pipes,
- the differential movement of drain tiles,
- moisture loading on foundation walls and basement floors,
- the saturation of floor slabs, or
- the flooding of basements or crawl spaces.
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 protected by the 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.
