Flooring expansion joints

For continuous floor widths over 6 metres, measured at right angles to flooring, intermediate expansion joints are required. This is in addition to the perimeter gaps.

This joint can be:

  • a single 10 mm wide gap, under a wall or across a hallway and the like
    or
  • smaller gaps with closer spacings to give an equivalent space, for example, 1 mm gaps at 1 metre spacing or loose cramping.
