Intent 1:
To limit the probability that the weathering of
pyritic material will lead to the heaving of footings, which could
lead to the movement or cracking of foundation walls.
This is to limit the probability of:
- compromised structural integrity of the foundation or
supported elements,
- where elements support or are part of an environmental
separator, the displacement or failure of required environmental separation
elements, which could lead to the deterioration of building elements,
or
- an inability to resist expected loads, which could lead
to
- the excessive deformation or deflection of walls, or
- the excessive deflection or vibration of floors.
This is to limit the probability of:
- the space being unsuitable for its intended use, or
- damage to the building.
