Abstract: | This study sought to identify the most dominant type of dampness associated with walls of residential buildings
in Ghana through a questionnaire survey of 5,800 residential buildings in the Dry Equatorial, South Western
Equatorial, Tropical Continental and the Wet Semi Equatorial climatic zones. A mixed method of data analysis
was used in which the symptoms associated with dampness were analyzed using severity indices and the most
dominant types of dampness were analyzed using percentages. Majority of the houses surveyed were of lateritic
materials and sandcrete block walls. The results showed that the most dominant symptoms in the walls of the
residential buildings surveyed were hygroscopic salts decayed skirting, dampness below 1.5m and mold growth
on walls up to 1m high. These symptoms point to the presence of rising dampness in the walls of these residential
buildings. The results provide a platform for addressing the problem of rising dampness in buildings. |
