【 摘 要 】

This article deals with diagnostics and current state of historical building in the grounds of the manor house Markuovce, eastern Slovakia. In the introduction, the problems of historical building, materials and structures are discussed. The next part is devoted to assessment of the selected structures, moisture survey and salinity above all. Determination of salinity shows high concentrations of chlorides, in part due to maintenance of local roads, which is in the immediate vicinity of the building.. Also, the high damp content of the masonry was confirmed due to the lack of waterproofing as well as high levels of groundwater. Near the historical building is a river Hornád that this fact suggests. The proximity of the park with trees and grassing turn causes shading of western and northern facade parts. The damp and shading of facade parts contribute to bio-corrosive manifestations, increased growth of moss and algae on the facade, and also confirm corrosion of masonry evidenced by higher sulphate content due to biogeneous sulfuric acid. The results of diagnostics tests show, that the samples from damaged parts of facade have a higher degree of salinity, this fact confirms the need for a reconstruction.
