Sažetak
Buildings in need of renovation also show typical substructural damages due to aged waterproofing. An often used reconstruction method against capillary rising damp is chemical penetration of masonry walls through injection boreholes, but the efficiency of this technology depends on the material of the wall. Surface coating and renovation plaster give additional moisture protection and together with the chemical injection based horizontal waterproofing provide a complete solution system. Analysis of posterior waterproofing of the soft limestone, a widespread building material of the previous centuries, is required due to its high porosity. In this paper, based on the results of the measurements of an insulated soft limestone masonry building, the effectiveness of the waterproofing system has been evaluated. The measured humidity data also gave opportunity to further research, so thermal and hygrothermal analysis and building-physical comparisons have been performed.
