The article deals with the problem of increasing the intensity of concrete surface impregnation with salts SiO2, Fe(OH)3 and Al(OH)3 in order to increase its strength. Absorption is possible due to the spontaneous rise of the liquid through the capillary-porous structure of the concrete. The intensification of this process is possible due to the use of electrical and ultrasonic energy and the introduction of substances into the composition of sols that reduce their surface tension – penetrants. The theoretical prerequisites for increasing the volume of impregnation when using electrophysical and physico-chemical influences are considered.
