Stone Columns

Menard - Piling Contractors Melbourne Stone Columns

Stone Columns are semi rigid inclusions, used in soft cohesive soils

Why is it used?

This technique is used to improve the engineering characteristics of loose granular soils or soft cohesive soils and is installed in a grid pattern in order to achieve a global improvement of the soil.

How does it work?

The columns are formed by the introduction of a vibrating poker into the ground: this poker is used to create the void in the ground into which stone backfill is introduced. The construction of the columns is achieved by the gradual introduction of the stone, progressing from the base of the column to the ground surface with the vibrating poker being used to compact the stone as the column is formed.


This technology is well suited for the improvement of firm and soft soils (silts, sandy silts, loams and non-homogeneous soils) as well as non-cohesive soils where enhanced properties are needed. Stone Columns are typically installed under the structures such as factories, warehouses, residential buildings, container terminals, road and rail embankments, etc.
