Intent 1:
To limit the probability of discontinuity in the
ground cover, which could lead to:
- the ingress of moisture that is not under hydrostatic
pressure from the ground, or
- the infiltration of soil gas.
This is to limit the probability of:
- an inadequate control of relative humidity,
- 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 or of elements protected by the separators.
This is to limit the probability of:
- negative effects on the air quality of indoor spaces,
and
- the inadequate thermal comfort of persons.
This is to limit the probability of harm to persons.
