More than 20 years ago, Rostov-based Promstroyniiproekt Institute (Research and Development Institute for Industrial Engineering), backed by Geotechnika group of companies and other organizations, commenced using cement grouting to stabilize soil as part of foundation soils of buildings. It has turned out that consolidation of water saturated by clay accelerates grouting and assures higher strength than the silicification method. The article describes a new method of grouting and a case study of grouting stabilization of the foundation soil of a five-storey residential house, made by subsiding soils and subjacent fluid-plastic clay loams.The work was complicated by the fact that clay was displaced by the cement-sand mortar injected at the pressure insufficient for formation of discontinuous cavities. In these circumstances, the team of researchers developed and implemented an integrated solution to avoid clay clustering under the influence of the injected grout.The authors consider problems arising in the course of operation of buildings in the above geotechnical environment and describe the sequence of grouting operations. The article includes the work performance pattern and patterns of building control.
