Objective

OS2 Structural Safety

Attribution

[F20-OS2.5][F22-OS2.4,OS2.5]Applies where the substrate for the tile contributes to the required bracing or lateral support for studs.
[F20-OS2.3]Applies where the substrate for the tile serves as a required environmental separation element or where the tile is installed to provide the required waterproof wall finish.

Intent

Intent 1:

To limit the probability that tiles:

  • will absorb water from the mortar, which could lead to inadequately strong mortar, or
  • will not be completely embedded in the mortar, which could lead to the inadequate adhesion of tiles to the substrate.

This is to limit the probability of the dislodgement of tiles or the ingress of water behind tiles, which could lead to compromised protection for moisture-vulnerable substrates, which could lead to the deterioration of the substrate, which could lead to the substrate being unable to resist expected impact, gravity or lateral loads.

This is to limit the probability of the deformation or detachment of interior finishes, which could lead to:

  • where the substrate for the tile contributes to the required bracing or lateral support for studs, the buckling or racking of walls, which could lead to structural failure, or
  • where the substrate for the tile serves as a required environmental separation element, the excessive deformation, displacement or failure of such elements, which could lead to further deterioration, which could lead to further compromised structural integrity.

This is to limit the probability of harm to persons.
