Abstract
Although ceramic tiling on building facades has a history of long durability and service life, a number of service life anomalies in modern buildings have occurred. To identify the factors and address this problem, a method is developed for the service life prediction of adhesive ceramic tiling systems based on a successful model for render and natural stone cladding. The focus is on the applicability of an empirical method of field data collection to this type of cladding that recognizes the complexity of ceramic tiling systems. A hierarchy of defects is defined to establish levels of degradation and identify the susceptibility to errors in design, execution and selection of materials. Results were validated using in-situ visual inspections of 117 tiling systems in Lisbon, Portugal. The aim is to provide a preliminary tool to estimate the durability of ceramic tiling systems and identify influencing factors. Ceramic tiling systems are particularly sensitive to the inadequacy of the materials as well as execution and design errors. Although 42% of the variance of the severity of degradation indicator can be explained by environmental agents, a larger 58% is attributed to design and installation errors.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
