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:

• the space being unsuitable for its intended use, or
• damage to the building.

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 damage to the building.
