Abstract:
Slab edge dampness is a condition related to the serviceability of a concrete raft footing. The major visible symptom of this condition is areas of dampness (sometimes with efflorescence) on the slab floor internally, adjacent the perimeter walls and on the exposed edge of the footing, externally. In areas with saline soils or where saline subfloor fills have been used efflorescence and 'salt attack' of the concrete surfaces usually follows. In South Australia the term 'salt damp' is used to describe what is broadly referred to as salt attack.
