Identification and Evaluation of Factors Influencing Damp Occurrence in Residential Buildings in Libya

Discipline / professional area
Built environment

Outline of research project

Damp is one of the most serious consequences of structural defects in building envelopes in East Libya. The use of waterproofing systems is not popular, despite their long-term financial benefit, due to the fact that such systems are expensive and require skilled workmanship. In the absence of quality control in Libya with regard to construction and the use of protection materials, in particular waterproofing courses, it is imperative that construction practice mistakes that lead to damp in houses be identified and evaluated so that they may be avoided in the future. 

The aim of this study was to investigate the issue of damp in building envelopes with respect to construction details as well as financial and socio-cultural considerations particular to Libya, in order for future projects to benefit from the lessons learned. A case study approach using questionnaires, photographs, observations and focus groups was the chosen methodology. The first phase identified the problem and its extent through distributing questionnaires to occupants and observing and photographing five damp properties. This study should be used to prevent water ingress in developing countries' construction projects now on the drawing board that have similar circumstances to this case study.
