“…This study sought to examine the problem of rising damp and salt attack in the walls of two residential buildings reported to be experiencing severe dampness problems using stages 3 and 4 dampness investigation approaches [2,7,11,12]. The survey building in case study 1 is a semidetached building that belongs to the Department of Urban Roads in Kumasi, Ghana (Figure 2 (Figure 2(b)).…”

Rising damp is one of the most severe phenomena that leads to decay and deterioration of both old and modern types of buildings. This study employed a holistic approach to dampness investigation and sought to examine the problem of rising damp in the walls of two residential apartments in Kumasi, Ghana. The study sought to determine the types of soluble salts and their concentrations in the soils and accumulated percentages in the walls over time and whether there exists any linkage between the salts in the walls and those in the ground. Results from the geotechnical survey of the building sites found that the soils on site 1 consisted of silty sandy gravel with some clay particles and those on site 2 consisted of silty sandy soil with some clay and traces of gravel. The study identified several groups of salts in the walls of the buildings, with the most damaging and dangerous being magnesium sulphate, magnesium chloride, and sodium sulphate salts. Similar salts were identified in the soil samples from the trial pits. The results therefore indicate a linkage between the salts found in the ground and those found in the walls and therefore confirm the presence of rising dampness.

“…It has been stressed that a lack of understanding about both the design and construction of the building envelope makes moisture related problems more likely (Kvande & Robert, 2009;Shabha, 2003) and Bertolini et al (2013) asserted that the factors causing deterioration of concrete can originate in the design phase. According to a study in Italy (Alfanoa, Chiancarellab, Cirillob, Fatob & Martellotta, 2006), the selection of a specific type of watertight protection must be based on a careful investigation of its structure and material, exposure conditions, water ingress mechanism and movement and drying, not simply trial and error. Therefore, the design of the building envelope (exterior walls and roofs with their exterior finishing)…”

An AHP damp penetration model for concrete houses: Green Mountain, Libya

The Green Mountain region of Libya experiences a persistent housing problem with regard to damp, regardless of the quality of the design, materials used, the construction practice and policy. This investigation into the factors influencing the performance of concrete housing to combat penetrating damp identified a broad range of factors: technical, managerial, economic, socio-cultural design and climatic issues. Consideration was given to specific national factors impacting on housing design and construction such as housing policy. The applicability of factors was confirmed by primary data collected from a householder questionnaire and a photographic observation survey of the condition of damp houses. Primary data were combined with secondary data in order to develop a more complete picture of the phenomenon under investigation. The analytical hierarchy process (AHP) technique was applied to construct an evaluation hierarchy of factors affecting the performance of houses in a Albeida city in North Eastern Libya. Factors were weighted and evaluated through interviews of construction professionals and self-build house owners. Results were integrated using the mathematical technique of AHP and a model of the most significant factors proposed. While the technique has been widely applied in various construction disciplines as a multiple criteria decision making technique, this study is the first to apply the technique as an analytical tool for understanding in depth a specific problem of construction and housing rather than for deciding a course of action. The results show that the issue mainly affects middle income and poor householders. Construction and socioeconomic design factors are the major causes of the presence of penetrating damp, together with the financial constraints of the owners. Surprisingly, management and climatic factors have less impact on the occurrence of damp. The model was subsequently validated in a sample of houses suffering from penetrating damp in Massa. This indicated that caution should be exercised regarding the application of AHP to the owners' judgments and the transferability of results. Whilst the findings of this research can assist decision makers in similar situations to identify appropriate assessment criteria for the construction of future housing projects, further investigation into the applicability of AHP in comparison with other methods is recommended. IV Acknowledgements I am most grateful to Allah Almighty for providing me with the patience and making it possible to produce this piece of work. I am also thankful to many people for their help and assistance, both directly and indirectly.
