Grouting Methods in Geotechnical Engineering: A Comprehensive Review and Outlook

The technique of rock and soil mass reinforcement has been widely used in engineering field and has solved many difficult problems in geotechnical engineering. As an important part of rock and soil consolidation technology, grouting method is also the most common foundation treatment method. Through pneumatic, hydraulic or electrochemical principles, some curable grout is injected into natural or artificial cracks or pores to improve various physical and mechanical parameters of the medium, so as to meet the needs of practical engineering. This paper reviews the development of grouting method, discusses the research status and technical characteristics of grouting method, and looks forward to the future development of grouting method from three aspects: grouting materials, admixtures and grouting technology.
