Intent 1:
To limit the probability of:
- a reversal of the slope leading to the sump pit,
- depressions that collect water,
- the contamination of granular layers by fines,
- inadequate percolation and drainage capacity close to
foundations, or
- saturation and a reduction in the soil's bearing capacity.
This is to limit the probability of
excessive moisture loading on foundation walls and basement floors,
which could lead to the accumulation of water under hydrostatic pressure,
which could lead to:
- 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.
