Intent 1:
To limit the probability of inadequate drainage,
which could lead to a perched water table, which could lead to the
accumulation of water under hydrostatic pressure, which could lead
to excessive moisture loading on foundation walls.
This is to limit the probability of:
- water ingress, or
- excessive lateral loading on foundation walls, which
could lead to the movement or cracking of foundations or building
superstructures.
This is to limit the probability of compromised structural
integrity, which could lead to:
- structural failure, or
- for environmental separators or elements supporting
environmental separators, the displacement or failure of required
environmental separation elements, which could lead to deterioration,
which could lead to further compromised structural integrity.
This is to limit the probability of harm to persons.
