| Essay:Rising dampWikipedia definition: "Rising damp is a condition caused by ground moisture rising up a masonry wall by capillary action. It occurs where there is no damp-proof course (DPC) or where the DPC has been damaged or bridged. Where present, moisture can rise up the wall to a height of a metre and it will often leave a characteristic horizontal 'tide mark'."Rising damp "is a common problem in older buildings. Moisture rises up the wall by capillary action depositing salts and damaging the wall finishes. However Rising Damp is less common than commonly thought and dampness at the base of a wall may be due to other damp problems such as Penetrating Damp and Condensation."-- EBS
