This paper considers the issues of improving the strength characteristics of foundations by injecting specially selected composite mortars into soils. The properties of injection mortars used in seismic hazardous areas are improved using various additives consisting of various wastes. The article explores the possibility of using a composite mortar modified with sulfur, which is waste from oil refining. The influence of its addition on the strength characteristics of composite materials is studied. The optimal content of sulfur addition was determined, which makes it possible to increase the strength of building mixtures by 20-30%. The possibility to use a sulfur- modified composite mortar to strengthen an artificial foundation for reducing the seismicity of the construction site was proven.
