9.14.2.1.(1)

Intent 1:

To limit the probability of excessive moisture loading, including hydrostatic pressure, on foundation walls and basement floors.

This is to limit the probability of water ingress, which could lead to:

• compromised structural integrity of foundation walls or 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.

Intent 2:

To limit the probability of excessive moisture loading on the soil immediately beneath the footings, which could lead to saturation and a reduction in the soil's bearing pressure, which could lead to compromised integrity of supporting soils, which could lead to failure of the foundation, which could lead to harm to persons.
