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, or
  • damage to a foundation's moisture-control elements.

For floors and elements supporting floors, this is to limit the probability of excessive deflection or damage, which could lead to rough or uneven floor surfaces, which could lead to persons tripping or falling, which could lead to harm to persons.
