Rising Damp ( a brief overview)
Rising damp is the name given to moisture from the ground moving up through the masonry pour structures via capillarity. For rising damp to occur there must be a source of ground water and It can be a seasonal effect and the geology of the ground is significant.
The height of rising damp will be affected by the masonry pour structure, volume of water at the base of a wall and the level of evaporation from the wall surface. Water rising up a wall by capillarity creates an electrical potential. negative ions travel from the positive ground through to the negative wall.
At the time of construction rising damp is stopped by installing a physical (damp proof course) barrier to moisture. Were there is no barrier or it has broken down then the following remedial rising damp control measures can be used:
