Intent 1:
To limit the probability that finished flooring
will collapse into open defects in the underlay, 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.
