9.12.3.3.(2)

Intent 1:

To limit the probability of excessive lateral loading on foundation walls or jacking pressures from adfreezing to foundation walls, which could lead to movement or cracking of foundation walls.

This is to limit the probability of:

• structural collapse of the foundation or of supported elements, or
• where foundations act as or support environmental separators, compromised environmental separation elements, which could lead to
  • condensation,
  • rainwater ingress, or
  • the ingress of moisture from the ground.

This is to limit the probability of the deterioration of protected or supported elements, which could lead to structural collapse, which could lead to harm to persons.
