Evaluation of Cracks in Affordable Housings in Selangor: A Fundamental Approach

Selangor, a densely populated state and economic hub of Malaysia, faces escalating demand for housing due to rapid urbanization and industrialization. This influx has led to a surge in affordable housing developments aimed at mitigating housing shortages and alleviating homelessness. However, many of these buildings suffer from structural defects such as cracks, which compromise their safety and longevity. This study focuses on investigating the prevalence, causes and impacts of cracks in affordable housing buildings in Selangor. Through case studies and expert interviews with a property manager, building surveyor and civil engineer, the research identified soil movement, vibrations, weather conditions and moisture changes as primary factors contributing to structural cracks. It revealed that 86 documented cracks across three buildings predominantly stem from soil movement (59 %) and underscores the urgency of proactive maintenance and non-destructive testing (NDT) to detect and address defects early. The findings highlight the necessity for tailored preventive measures and regular inspections to enhance the structural integrity and durability of affordable housing in Selangor, thereby ensuring safer living conditions for residents.
