Intent 1:
To limit the probability of:
- [Clauses 9.14.5.2.(1)(a) and 9.14.5.2.(1)(b)] silting-up of the sump pit, which
could lead to the ingress of moisture from the ground, or
- [Clause 9.14.5.2.(1)(c)] excessive moisture transfer
from the sump pit into interior spaces, which could lead to high relative
humidity.
This is to limit the probability of:
- compromised structural integrity of foundation walls
and basement floors, or of elements supported by the walls or floors,
or
- deterioration, which could lead to compromised integrity
of elements supported or protected by exterior foundation walls.
This is to limit the probability of harm to persons.
