Typical Moisture Failures of Slab-on-Ground Structures in Finland
Publication: Practice Periodical on Structural Design and Construction
Volume 10, Issue 2
Abstract
This paper includes a summary of several case studies on moisture-damaged slab-on-ground structures. The object of the paper is to suggest a classification of the causes for moisture damage and introduce the typical moisture failure of slab-on-ground structures in Finland. The common causes for moisture damage in the slab-on-ground structure can be classified into four categories: design, construction, repair, and maintenance. According to the studied moisture-damage cases, the most common cause is design fault. Usually the slab-on-ground structure is unfit in the light of present knowledge. The most common design faults are lack of a capillary breaking drainage layer under the slab, lack of thermal insulation, and incorrect placement of the vapor barrier.
