Results are cited for investigations based on a set of optimal parameters of cement-grout injection for strengthening of a soil mass with use of cup technology during hydrofracking. It is shown that the method of multiple injection in each horizon of the soil mass contributes to more effective formation of zones of active hardening of soil under lower pressures and shorter grout-injection times
