The method for dehumidification of buildings that are damp as a result of capillary rise of water from the ground, by crystalline injection, consisting in that a mixture of water solution of Portland cement and an activating agent in the form of sodium metasilicate and/or sodium polysilicate with an addition of sodium phosphate is introduced to holes drilled specially in the buildings, preferably made at the same level every 12-16 cm at an angle of 15-30 degrees, most preferably in the cement : activating agent weight ratio from 1:1 to 10:0.2, with an addition of water in such quantity so that the mixture constitutes a uniform liquid, whereas the weight ratio of the activating agent components, i.e. sodium silicates, to sodium phosphate being from 10:1 to 10:3, and just before the mixture of the injection agent is introduced, the injection holes are dampened with water in the quantity at least equal to the volume of the holes.
