| Abstract: | Underground car parks face increasing challenges from groundwater leakage, a growing issue exacerbated by rising groundwater levels and intensified rainfall caused by urbanization and climate change. These leaks not only threaten the structural integrity of these facilities but also pose safety hazards, disrupt operation, and lead to substantial financial losses for property owners. Traditional drainage systems and existing waterproofing measures often fall short of addressing the complex and site-specific conditions of preventing groundwater infiltration. As urbanization continues and extreme weather events become more frequent, there is an urgent need for a systematic approach to evaluate and select effective waterproofing techniques. This thesis aims to address this gap by developing a structured methodology to evaluate and select the most suitable waterproofing techniques for preventing groundwater leakage in underground car parks. The proposed approach employs a Multi-Criteria Decision Analysis (MCDA), supported by the Analytical Hierarchy Process (AHP), to compare alternative solutions systematically. The methodology introduces a set of evaluation sub-criteria, divided into main-criteria: performance, environmental impact, efficiency, and applicability. To demonstrate the applicability of the methodology, a case study was conducted at P6 Uitgaansdriehoek in Amsterdam, a site facing persistent operational challenges from groundwater infiltration. The study assessed multiple waterproofing solutions, including cementitious, bituminous, and crystalline techniques, using expert surveys to determine the relative importance of criteria and a scoring model to rank the alternatives. The results identified Sika® Igolflex 301 as the best-performing solution due to its superior waterproofing capabilities and high applicability, while SikaTop® Seal-107 was deemed the most cost-effective option, offering an optimal balance of performance and cost. This report provides a practical and adaptable decision-making framework on the selection of waterproofing techniques. While the methodology demonstrates significant promise, areas for future refinement include the incorporation of advanced decision-making models, such as fuzzy logic systems, and the exploration of new innovative waterproofing materials to enhance durability and sustainability. |
