Need to repair moisture- and mould damage in different structures in finnish public buildings

Abstract

Moisture- and mould damage and resulting impurities are related to complex indoor air quality problems. This study focuses on the need to repair moisture- and mould damage in different structures. The research material consists of 168 Finnish public buildings. Based on research material, the highest need for repair is in timber-framed ground floor with crawl-in space, slab-on-ground structures, external walls in concrete-framed buildings and walls in contact with soil. A need to repair these structures exists in 56–85% of the examined buildings. The study reveals that buildings are multi-problematic: on average 3.1 main category structures were damaged in every studied building.
