The article is devoted to the study of the moisture capacity of medium-grained sandy soils. Samples of sandy soil in the Upper Kurya area of the city of Perm were taken for research. The sandy soil is mainly represented by medium-, fine- and fine-grained fractions. The subject of the study is a medium-grained sandy soil represented by one fraction. For this fraction, humidity is established along the section and 3 moisture zones are identified: constant humidity, transition zone and maximum humidity. The total moisture capacity (Wt = 22.3%) and incomplete hygroscopic moisture capacity (Wg = 0.3%) was determined. The results on height and speed of capillary uplift are obtained. The maximum height of the capillary rise was 126 mm in 72 hours. The rate of capillary uplift was maximum in the first hours, during the following hours it practically did not change and stopped after 72 hours.
