In evaluation of the state of moisture of courting walls one needs data of the intensity of the rainfall on a vertical surface of the construction (wind-driven rain) WDR and of the absorption coefficient of the rain. In this work a mathematical model is presented which allows to estimate the state or moisture of courting wall s under the action of wind-driven rainfalls. This model does not require the use of the average rain absorption coefficient proposed by Kunzel (i.e., it allows to avoid averaging of water absorption ability of the material) and increases the accuracy of the estimation of the state of imbuement of courting walls, in some cases on 30% (depending on climatic conditions).
