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.
