The jet-grouting piles construction and testing in collapsing soils experience

For a number of years the company New Ground has been providing research and development work to expand the scope of jet cementation technology in various soil types, to develop monitoring methods and basic quality parameters of work performed, including housing construction in the southwest of the Russian Federation in conditions of the first and second types collapsing soil. The jet-grouting piles construction in collapsing soils of solid and semi-solid consistency has a number of technological features compared to weak water-saturated soils, and requires advanced quality control methods for structural and technological solutions. The presented materials describe the experience of the development work production on the jet-grouting piles installation and testing in collapsing soils of the second type.
