	Aerated concrete is the basic building material applied in traditional building industry. It is mainly caused by its thermal parameters - heat conductivity coefficient λ for lighter brands of this material is many times lower than other traditional materials like brick etc. Low value of heat conductivity coefficient is mainly caused by the material structure which is highly porous. This porosity causes capillary forces which are the reason of so called capillary rise phenomenon being the reason of many buildings destruction. This article presents the possibility of monitoring and quantitative valuation of moisture increase in building barriers due to capillary rise with the application of the TDR surface probes enabling quick and noninvasive moisture determination in porous building materials. The analyses conducted using surface TDR probes will be compared with the examinations made using other electrical methods and the results will be presented in the form of moisture profiles changing in time.
