Vibro-Replacement is the process of constructing stone columns using a vibratory probe (vibroflot). After the vibroflot penetrates to the desired depth of treatment, stone fill is deposited into the hole from the ground surface or through feed tubes to the tip of the vibroflot as it is withdrawn. Repeated raising and lowering ("plunging") of the vibroflot into the stone during withdrawal results in columns of stone measuring 30-42" (750-1100mm) in diameter. As with vibro-replacement, stone columns results in higher bearing capacities for shallow foundations, a reduction in total and differential settlement, increased safety factors for slope stability, and mitigation of liquefaction potential in seismically active areas. Vibro-replacement is often an economical alternative to deep foundations, especially when considering the added liquefaction protection in seismic areas.
Vibro Replacement is a method of constructing stone columns through fill material and weak soils, to improve their load bearing and settlement characteristics. Vibro Replacement provides an economic and technically sound solution to a wide range of geotechnical and foundation problems.

Product Description
Application
Mixed and fine-grain soils frequently have an insufficient bearing capacity and stiffness. Should the fine grain share be around 5% higher, an adequate self-compaction is no longer to be expected. This is where the vibro replacement compacting comes into question as an improvement. This process is also suitable for the improvement of coarse-grain backfills comprising rubble, slag or overburden.
A special area of application are vibro drain columns. Flotation is dispensed with hereby. The column then merely acts as a drain.
Function
The vibro replacement
In most cases, a bottom feed vibrator is used, with which a coarse-grain fill material is discharged at the tip of the vibrator with compressed air support. The vibrocats with a leader that have been designed by Keller provide an additional pull-down pressure to be applied when the vibrator is being lowered and is compacting.
In vibro replacement compacting, the work is carried out in alternate steps. The gravel or crushed stones that are discharged from the vibrator hub are compacted and displaced into the soil at the side. This results in the formation of replacement columns that bear the loads in connection with the soil. The creation parameters are digitally recorded in the device.
