Factors Affecting Water-Tightness in Wet Areas of High-Rise Residential Buildings

Abstract

Defects related to internal water leakage in wet areas of 1500 high-rise residential building blocks between 0–35 years of age were studied. The problem type, the extent of the problem, the mechanism, the implications of design; construction material and maintenance, and the local and international standards; codes of practices; good practice guides etc governing the aspects were discussed.

The study highlights the significance of ensuring close interaction right from the planning and design phases between professionals including the maintenance team. The cases presented show the importance of reviewing structural, architectural and M&E issues using an integrated approach throughout the whole building delivery process.
