The designer should consider:

  • A) the finished floor surface;
  • B) the screed/direct finished slab surface;
  • C) the base slab to receive a screed;

When specifying departure from datum and surface regularity, taking into account the types and thicknesses of the flooring and the levelling screed. For a floating screed, the thickness, and the variation in thickness, of the insulating layer should be taken into account.

Some variations in surface regularity may be allowed without detriment to the satisfactory application of the flooring: the permissible limits associated with surface regularity and departure from datum depend on many factors. In general, the thinner the applied flooring the higher the class of surface regularity required.
