Experiences of causes
of moisture damages
The activities in damage
investigations have resulted in a
chronological ”collection” of
identified causes of moisture
damages and moisture problems in
floor structures and foundations.
The “collection” includes
impermeable floor coverings,
expanded clay particles in a
capillary breaking layer, outdoor
ventilated crawl spaces, CCA-impregnated
wood, heat insulation as a moisture
barrier, water-based adhesive for
wood-particle floor boards,
self-levelling compounds with
casein, PVC plasticizers,
alkali-silica reactive aggregate,
lost formwork, self-desiccating
concrete, wooden floor tiles and
parquet, floor heating, etc.
