Abstract

Identification of leakage sources is itself a perplexing process and needs expert views from experienced work and trade specific professionals. Comprehensive strategies relevant to work methodologies are to be implemented that prioritises durability and efficacy of waterproofing system. Leakages when identified at final stages of building handovers induces a high cost in repair and maintenance of defects pertaining to waterproofing failures or due to non-consideration of leakage prevention measures at the design and specification establishment stages. Despite of a thorough technical knowledge even seasoned civil engineering professionals and even waterproofing specialists are not aware of the probable root causes of observed leakages. Various factors contributing to leakages through different areas of buildings are mentioned along with preventive measures in relation to process enhancement, workmanship, materials, etc. in relation to prevention of leakages. Photographic examples of different types of leakages are provided for an easy understanding of non-technical users regarding the kind of defect being discussed. This study represents a comprehensive review of different types of leakages observed in buildings and their root causes. Solutions based on type of leakage along with the specific materials and method orientation for the relevant leakages is also covered in the study. Waterproofing is an essential aspect and integral part of building construction which ensures the durability, longevity, and structural integrity of buildings. Proper waterproofing safeguards the structure from observable and non-observable damages such as internal or external structural disintegration, Waterproofing although being a complicated activity, is highly generalized in terms of materials to be used. This research explores the different types of materials and their required specifications to be used or not to be used at a particular location in buildings along with listed reasons.
