The exposure of massive historical masonry walls to varying climatic conditions represents a crucial factor for long-term damage related to moisture and soluble salts increase. Moisture movement in the porous structure of massive historical masonry wall driven by capillary forces is usually connected with transport of salt solutions, which can be responsible for a severe damage. Because of missing damp-proof insulation layers, the moisture ingress carrying soluble salt from the ground especially during winter periods is not prevented from. This study is aimed on the evaluation of the effect of commonly used restoration works on the conservation of an exposed building. The influence of applied precautions was continuously monitored by time-domain reflectometry probes in various depths and heights of the studied masonry wall located in the basement of a residential house in Prague, Czech Republic. Based on the obtained results, taking into account also the influence of indoor and outdoor temperature and relative humidity variations monitored by combined temperature/relative humidity sensors, the wall drying process and the success of applied methods is analyzed.
