The analysis of the main reasons for the formation of efflorescence in brickwork in the Aral Sea regions is presented. It has been established that as a result of alternating moistening and drying of the building material, during which the crystallization of salts in its pores occurs, the formation of high-water crystalline hydrates with an increase in volumes exceeding the pore volume of the material leads to the appearance of pressure that destroys the building material. External signs of salt corrosion are peeling and chipping of ceramic bricks. The features of salting out in ceramic bricks in the Aral Sea conditions are indicated.
