The conversion of capillary suction of moisture from the ground into the porous masonry building materials like brick, stone, mortar, and earth is termed as riding damp. Problem creates when the moisture evaporates from inside or outside of the wall surface that leads to more absorption. The rising damp measures between 0.5 to 1.5 b above ground level which is considered as the normal limit. It is determined by two factors: evaporation rate and kind of the wall. Other symptoms of rising damp appears like stain on the wall paper, blistering of paint, loss of plaster , and at interior parts of the home in case of damp severity. Also the resulted damp walls lead to moulds growth. Sometimes high humidity creates health problems among the occupants. The fretting and crumbling of the masonry at the base of the walls is jut nothing but external appearance of damp zone.
Other forms of damp are falling damp and penetrating damp. It can be treated by applying damp-proof-course known as DCP. Other methods too can be applied like preventing its recurrences by fixing leaks, by removing bridges, or by inserting a new DPC. Besides, constant maintenance of plumbing and roof, guttering systems, proper care of the site drainage, under floor ventilation etc., needed to be taken into consideration.
