“…This paper describes the use of an expert system for the systematic statistical characterization of the pathology, diagnosis and repair of 119 IGP coatings and the resulting important lessons that can be learned from this field study. The IGP inspection system used has been described in detail in another paper by the authors (Pereira et al 2010) and includes a classification of all the defects that can affect IGPs, together with their causes. This paper also presents a detailed statistical analysis of the results of the inspection programme, including the diagnosis methods used to characterize the defects and confirm their causes and the most appropriate repair solutions.…”

This paper provides the statistical characterization of the pathological situation of 119 gypsum plaster coatings applied to partition walls and ceilings (inner gypsum plasters -IGP), the diagnosis methods that can be used to characterize the defects and confirm their causes, and the most suitable repair solutions. The results presented in this paper were achieved via the use of an expert system developed by the authors in an extensive inspection programme covering 23 buildings. A comprehensive set of charts and their detailed statistical analysis describe the results achieved, including the characteristics (temporal, spatial and severity) and frequency of the defects in the sample and the main causes of their occurrence in walls and ceilings. The most appropriate diagnosis methods, preventive measures and repair solutions prescribed for these defects in the sample are also analyzed and the most significant correlations presented. Even though in some instances the pathological situation of IGP is common knowledge, this time it has been characterized via quantitative indicators and using a statistically significant sample, which means that important lessons can be learned.

“…This methodology has thus been tested and implemented in various cladding systems/construction elements (Silvestre, de Brito 2009;Pereira et al 2011;Neto, de Brito 2011;Sá et al 2011). (Duarte 2011) Besides the proposed innovative expert-knowledge management system specifically tailored for ETICS in walls, this paper presents the statistical evaluation of the results of an inspection program of ETICS, that is unprecedented in the literature in terms of size of the sample analysed, scope of the analysis (pathology, diagnosis and rehabilitation) and systemic approach to data collection and analysis.…”

Abstract. This paper presents a statistical survey on the pathology, diagnosis and rehabilitation of ETICS (external thermal insulation composite system) in walls. The development of an expert-knowledge inspection and diagnosis system for this type of cladding implied the creation of classification lists of anomalies, most probable causes, diagnosis methods and repair/maintenance techniques. The collection of data through field work where the tools developed within the proposed system were applied was the basis for this statistical survey. The field work consisted of the visual inspection of 146 façades with ETICS cladding located in various areas in Portugal and aged from 3 to 22 years. The data obtained enable anomalies to be related to their causes and so conclusions can be drawn on the best way to minimize the development of the former and eliminate the latter, at the design and application stages. The study further revealed the main sensitive issues of the cladding system during its service life, highlighting the importance of a correct maintenance plan.

“…However, most research has examined the plasterwork as a support to determine its composition [10], looked at historical lime or gypsum mortars [1,[13][14][15][16][17][18], or studied the pathologies and interventions for gypsum finishing coats [19][20][21][22][23]. There are no specific methodologies documented, though, on the study of historic plasterwork microlayers.…”
