ADPC property Care

 The height of rising damp is controlled by the thickness of the wall, masonry pour structure size and the volume of water at the base of the wall and rate of wall surface evaporation.  

When water rising up a wall by capillarity it creates an electrical potential and negative ions travel from the positive ground through to the negative wall.

Note: If you see a black spackled mould growth rising up from your floor level, this is not true  rising damp it is normal condensation.

At the time of construction rising damp is controlled by installing a physical barrier to moisture called a Damp Proof Course. In Edinburgh I have seen this work in building work from 1830.  Where there is no DPC or it has been bridged or broken down then, the following remedial rising damp control measures may be used:

Rising Damp ( a brief overview)

Rising damp is the name given to one form of dampness, which only comes from ground water, moving up through  interlinked masonry pour structures via capillarity. For it to occur there must be a suitable source of ground water at the base of a wall and the abases of a damp proof course.
