All the following factors should be taken into account in the design and specification

  • a) After a concrete floor has been constructed, the concrete is liable to undergo changes in moisture content and temperature that can affect its level and surface regularity over a period of time.

  • b) Over the period that the concrete is developing strength, during the first seven days or so after laying, differential thermal contraction between the top and bottom surface of the slab can cause it to curl at the joints.
  • c) The majority of differential drying shrinkage of the slab between its top and bottom surface takes place over the first year and can cause curling, particularly around joints.
  • d) Deflection of suspended slabs under load with time can cause changes in level and surface regularity.
  • e) Settlement of ground-supported slabs due to compression of the sub-grade under load with time can produce changes in level and surface regularity.

Where required, a survey to assess the floor should normally be made within about a month of completion. It should however be recognized that after this time the level and surface regularity could still change.
