Causes of Dampness in Building; Using Agbale as Case Study

Dampness in buildings poses significant challenges, particularly in rural areas where construction practices and environmental conditions often facilitate moisture ingress. This study examines the primary causes, impacts, and mitigation strategies of building dampness in these settings. Utilizing structured questionnaires, data were collected from Agbale, Ede, Osun State and analyzed using Statistical Test of significance (STS). The analysis identifies poor drainage, inadequate waterproofing, rising damp, and the use of substandard construction materials as prevalent causes of dampness. Seasonal factors, notably increased rainfall, intensify moisture accumulation. This project highlights the economic implications, including elevated maintenance costs and property devaluation, as well as health risks such as respiratory ailments and allergic reactions linked to mold proliferation. Recommendations include strategic site selection, implementation of effective damp-proof courses, improved ventilation, and routine building maintenance. Policy suggestions advocate for stricter enforcement of building codes, public education initiatives, and incentives for the adoption of high-quality waterproofing materials. Future research should explore advanced moisture detection technologies and sustainable construction methods to address dampness efficiently and environmentally responsibly.
