Strength of the soil and the nature of its deformation depends on the strength of the structural links between the particles, grains and aggregates in the soil. Despite detailed studies of clays, the question of evaluating the forces of electrostatic interaction between clay colloids has not been studied sufficiently. Therefore, the aim of the work is to evaluate the adhesion forces on the surface of colloids of kaolinite clay upon its compression. Pre-prepared samples of kaolinite clay were studied on an atomic force microscope in fields of view from 50x50 to 1x1 mkm. As a result of the work, the dependence of the change in adhesion forces of kaolinite clay on the degree of its compaction. The statistical relationships between these indices have been revealed, which allow predicting the adhesion force on the surface of colloids and the material of the binding colloids depending on the compression force of kaolinite clay.
