Intent

Intent 1:

To limit the probability of:

  • an inadequate flow of drainage, which could lead to water ponding under footings or floors-on-ground, or
  • an inadequate disposal of drain water.

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:

  • 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 capacity, which could lead to the failure of foundation walls and basement floors, which could lead to damage to the building.
