Vibro stone columns are a quick and cost-effective foundation solution. As an alternative to traditional piling or deep trench-fill, this is a displacement technique meaning it produces minimal spoil.
A vibro stone column is constructed by the penetration of the vibroflot into the ground to the required design depth. This creates a bore which is then filled with primary or recycled aggregates, and compacted in increments to produce a dense, interlocking stone column.
Within granular soils, the introduction of a vibro stone column and the vibratory action of the vibroflot itself improves the density of the ground. Within cohesive soils, vibro stone columns act as ‘reinforcing’ elements and improve overall settlement performance.
