	Capillary rise is a dangerous phenomenon touching many objects built of aerated concrete which is a porous material and highly prone to water influence in case of any horizontal water insulation failures. Aerated concrete is the artificial building material offering both suitable strength parameters and heat insulation properties. Water migrating from the ground to the walls of the building negatively influences not only its construction but also increases heat loses and decreases indoor air comfort (low temperatures, fungi and bacteria development) which is in the World’s literature called SBS (Sick Building Syndrome). All above presented facts connected with water migration through the aerated concrete walls underline the need to monitor and simulate capillary rise phenomenon in building envelopes made of aerated concrete. The paper presents the simulation of capillary rise in a model aerated concrete sample. The model applied for simulations will be based on the Richards equation for water flow in unsaturated conditions. The model is commonly used in agrophysics and this work is an attempt to use it for building materials. The simulations results will be verified with laboratory experiment of capillary rise in the real samples of aerated concrete equipped with Time Domain Reflactometry (TDR) probes which will enable to monitor the phenomenon propagation.
