Analysis of moisture and salinity of historical constructions before and after the application of REMEDIATIONS

Negative effects of humidity in historic buildings can be considered as phenomenon that is perceptible on most of these constructions. Along with the problem of humidity, the salinity of wet walls can also be observed visually, that also in a large extent helps to destroy and gradually degrade particular structural elements and subsequently entire buildings. This article is going to describe the research dealing with the content of water-soluble salts and the degree of wetting on selected historical buildings in Slovakia. In the article are adduced the individual values of humidity measured at several places in the building and also describes the results of laboratory analyses of the amount of water-soluble salts in the investigated constructions. Subsequently, the article describes the technologies used in the rehabilitation of these structures and describes the effectiveness of these interventions against moisture, which are also presented by in situ measurements after the implementation of specific technologies. •Renovation of historical constructions with undercutting.•Research of salinization of historical constructions.•Application of remediation technologies as undercutting, driving of stainless sheets, chemical grout.
