To limit the probability that weathering of pyritic
material will lead to excessive loading on foundation walls, under
lateral soil pressure, with attendant structural damage to the foundation
This is to limit the probability
- compromised structural integrity of the foundation or
supported elements, or
- where the foundation serves as or supports an environmental
separator, compromised environmental separation elements, which could
lead to condensation, rainwater ingress or the ingress of moisture
from the ground, which could lead to deterioration of building elements,
which could lead to compromised structural integrity.
This is to limit the probability of damage to the building.
