Intent

Intent 1:

To limit the probability of the deformation or displacement of underlay at joints, which could lead to the displacement or cracking of finished flooring.

This is to limit the probability of:

  • rough or uneven finished floor surfaces, which could lead to persons tripping or falling, or
  • where finished flooring is required to provide water resistance, the ingress of water into the subfloor, which could lead to compromised physical integrity of the supporting structure, which could lead to uneven finished floor surfaces, which could lead to persons tripping or falling.

This is to limit the probability of harm to persons.
