The article presents the analysis the degree of clogging of mechanically formed cracks by new growths induced as a result of the urease activity of bacteria in model solutions. Intensification of the induction of new formations depending on the type of bacterial culture is characterized by the formation of positive reliefs on the surface of the cement stone. The continuous fouling of the inner surface of the formed fault by crystals of various morphologies formed as a result of the enzyme activity of bacterial strains is visualized. The authors propose the method for calculating the area of an asymmetric fracture with different widths of the convergence of parts. The results of the intensification of precipitation of crystals are determined by the coefficient of crack closure. On the basis of comparative analysis of bacterial cultures by the intensity of continuity reattachment in the fracture zone, they were ranked according to the increase of efficiency of the following sequence: S. pasteurii → B. pumilus → B. megaterium → L. sphaericus.
