Water leakage in buildings is a critical issue affecting structural integrity, aesthetics, occupant safety, and long-term maintenance costs. This study identifies the causes of water leakage, evaluates waterproofing methods, and suggests remedial measures. The research involves literature review, case study analysis, and a survey of waterproofing materials. The findings highlight that improper construction techniques, poor waterproofing materials, plumbing failures, and environmental factors contribute significantly to water ingress. Advanced waterproofing solutions, including polymer-based coatings, integral waterproofing, and non-destructive testing methods, are recommended for effective prevention and mitigation.
