Application - movement joints
3.40
FORM MOVEMENT AND EXPANSION JOINTS

Install movement joints to go right through the tile and bed to the background, maintaining any waterproofing.  Ensure any slip layer backing (bond breaker) required, is installed.  Joint width minimums:

 

  • 4-6mm interior tiles on concrete (with low moisture content)
  • 6-8mm interior tiles on dry timber structure
  • 8-10mm exterior tiles on concrete (with low moisture content)
  • 10-12mm exterior tiles on dry timber structure
  • To match grout width, if equal/larger than above
  • Larger to suit joint infill requirements (preformed jointers)

 

In wall tiling provide joints at; internal vertical corners, as well as joints at, floors, columns/beams, nibs, hobs and similar. Provide joints around sanitary fixtures, around fixtures interrupting the tile surface, at junctions with joinery fixtures, including window and door frames and built in cupboards, and at changes in substrate or background.  In large area wall tiling provide vertical joints at not more than 3.6 metres spacing along the length of a wall and horizontal joints at each storey rise in the height of a wall, and over all existing substrate expansion joints.

 

In large areas of floor tiling provide joints at not more than 4 metres spacing in both directions and 3.6 metres externally.  Provide expansion joints, at the perimeter of tile floors, at changes of level or slope, around structural features, changes in substrate, around sanitary fixtures and other fixtures interrupting the tile surface, and over all existing substrate expansion joints.

Joint width minimums above, based on light coloured porcelain tiles on unheated surfaces.

Joint width minimums must be increase if greater movement is expected due to, structural movement, tile or substrate types, heat expansion due to direct sunlight or floor heating, dark tile colour exposed to sunlight, pool surrounds,  For instance, Marble may expand when heated 10 times more than a Porcelain.

It is recommended to detail mid-wall or mid-floor locations on the drawings.  Modify clause to suit project.

3.41

Access route - explanation

 

LW - Level access wet

  • Refers to level access routes expected to become wet with water in normal use.
  • Level surfaces include surfaces with slopes no steeper than 1:50.
  • An SRV classification of 39 is the minimum value required.
  • A slip resistance value of 0.4 when tested under AS/NZS 3661.1 may be assumed as equivalent to a SRV of 39.
  • Imported materials are often tested by a ramp test equivalent to Appendix D of AS 4586. While this is an oil wet test using an industrial work shoe, an R11 result will often be equivalent to an SRV of 39 for water wet conditions. Additionally, the ramp test is suitable for heavily profiled surfaces for which AS 4586 Appendix A is not applicable.

 

SW - Sloping access wet

  • Refers to sloping access routes expected to become wet with water in normal use.
  • Sloping surfaces include slopes greater than 1:50 but less than 1:10 for wet conditions.
  • An SDV (slope design value) is the mean BPN (British Pendulum Number) required on a slope of a known maximum gradient.

 

WRN - Stairs wet - with slip resistant nosings

  • Refers to stairs with slip resistant nosings (at least 50 mm wide) expected to become wet with water in normal use.
  • The acceptability criteria is based on the requirements for Level access wet (LW).
  • WWN - Stairs wet - without slip resistant nosings

 

WWN - Stairs wet - without slip resistant nosings

  • Refers to stairs without nosings expected to become wet with water in normal use.
  • The acceptability criteria is based on a slope of 1:10. The 50 BPN value indicated in the "Minimum test value required" column is derived from a SRV (slip resistance value) of BPN 39 (minimum required for level access routes expected to become wet with water) for a slope of 1:10 and should be considered as a minimum value.

 

BF - Wet areas primarily used barefoot

Refers to areas that are primarily used barefoot, such as around swimming pools and adjacent to communal showers.

 

CWS - Contaminated walking surfaces

  • Refers to walking surfaces that may be contaminated by oils and similar slip-inducing materials in use, typically industrial and commercial situations.
  • D1/AS1 comments indicate that table 3B of SA HB 198 lists suggested R-values for a range of commercial situations, table 3B indicates an R12 value for commercial kitchens and loading docks under cover.

 

LD - Level access dry

  • Refers to Level Access routes expected to remain dry under normal use.
  • Level surfaces include surfaces with slopes no steeper than 1:50.

 

SD - Sloping access dry

  • Refers to sloping access routes expected to remain dry under normal use.
  • Sloping surfaces include slopes greater than 1:50 but less than 1:8 for dry conditions

 

DRN - Stairs dry - with slip resistance nosings

  • Refers to stairs with slip resistant nosings (at least 50 mm wide) expected to remain dry in normal use.
  • The acceptability criteria is based on the requirements for Level access dry (LD).

 

DWN - Stairs dry - without slip resistance nosings

  • Refers to stairs without nosings expected to remain dry in normal use.
  • The acceptability criteria is based on a slope of 1:10. The coefficient of friction value indicated in the "Minimum test value required" column is derived from AS 4586 Appendix F for a 1:10 slope, using a 0.40 COF (coefficient of friction) value, which is the minimum value given in D1/AS1 for level access routes expected to remain dry under normal use.
