FIELD: construction engineering and other industries. SUBSTANCE: method is used for inspecting piles and foundations made by injecting binding materials into ground through at least one dispensing member displaced in soil mass. Binding material is doped with substances that make liquid column material magnetically susceptible their characteristic sedimentation time being longer than material setting time; characteristics of liquid column, primarily its shape and quality, are determined by magnetic permeability of material in the course of displacement of mentioned dispensing member. EFFECT: improved quality and stability of piles and other structures produced by proposed method. 6 cl, 1 dwg
