ABSTRACT
In very soft soils, the use of stone columns can be problematic due to the lack of
adequate lateral confining pressure. In these situations, to provide the required lateral
confining pressure and to increase their bearing capacity, stone columns can be
encased by a suitable geosynthetic. Using a high-strength geosynthetic for
confinement not only increases the strength of a stone column, but also prevents
lateral squeezing of the column due to movement in the very soft surrounding soil.
