The results of experimental research on the strength and deformation characteristics of soil-concrete as a function of jet-grouting parameters are described in this article. Some experimental works of jet-grout column construction in sandy ground are carried out. At the end of these works soil-concrete samples are taken and laboratory research is carried out. Relationships between the deformation modulus (E), compressive strength and tensile strength and the cement consumption per 1 m³ are obtained.
