Inspection and diagnosis system for gypsum plasters in partition walls and ceilings

This paper presents an expert system to support the inspection and diagnosis of gypsum plasters applied to partition walls and ceilings (inner gypsum plasters – IGP). This system includes the classification of the defects that may affect IGP and their probable causes, which is complemented by the correlation matrices between defects, and between defects and probable causes. It is completed by a classification of the diagnosis methods and the repair techniques suitable for each IGP defect. Individual files containing a complete characterization of defects, diagnosis methods and repair techniques are also exemplified. This inspection system was validated through standard inspections of 119 IGP applied in walls or ceilings in 23 buildings.

Research highlights► An inspection and diagnosis system for inner gypsum plasters is proposed. ► The systematic approach used to build this inspection system is innovative. ► This inspection system was validated in an extensive inspection campaign. ► Inner gypsum plasters are high susceptible to the action of water. ► This coating solution must be carefully applied on-site and properly maintained afterwards.
