Tile Delamination on Façades of Tall Buildings

Tile delamination on the façades of tall buildings poses significant concerns for public safety worldwide. This study investigates the underlying causes of tile delamination and their linkages with other prevalent façade defects in order to develop a risk assessment for preventing future tile delamination in tall buildings. Drawing on Singapore’s experience, data were gathered from case studies through field inspections and expert interviews. The results have been supported by data findings and past laboratory testing conducted in the Singaporean context. The findings indicate that the main causes of tile delamination in Singapore’s tall buildings are linked to design, workmanship, materials, and environmental conditions. Notably, cracks and water penetration often indicate a high risk of tile delamination, highlighting a strong connection between delamination’s root causes and their frequent occurrence on tile façades. Finally, this study gives recommendations for designers, constructors, and maintenance teams to mitigate and eliminate risks associated with tile delamination, aiming to enhance the safety and durability of building façades.
