Abstract

Waterproofing failures are a pervasive problem in the construction industry, leading to costly
repairs, structural damage, and safety risks. While some research exists, there needs to be
more focus on identifying the most frequent failure areas and their root causes. This research
addresses this gap by developing a robust quality framework for waterproofing systems. A
thorough literature review established technical and procedural best practices. Subsequently,
a Quality Management System (QMS) specifically for waterproofing was designed to align
with ISO 9001:2015 standards. Seven case studies were analyzed to identify common quality
failures, such as inadequate curing, incorrect mix usage, and insufficient testing. An expert
survey employing the Relative Importance Index (RII) method confirmed these findings.
Finally, expert interviews were conducted to develop actionable strategies for effective QMS
implementation, emphasizing rigorous curing protocols, enhanced training and supervision,
and proactive inspection practices. This research provides a comprehensive quality
framework to guide industry professionals, aiding in reducing waterproofing failures and
optimizing the longevity of waterproofing systems.
