Vibrocompaction is the compaction of loose granular soils by penetration of a vibratory probe or vibroflot.

In granular soils, the probe penetration results in the liquefaction of the surrounding soils and a quasi-immediate settlement.

Based on the results from a test zone, DGI-Menard finds the optimal probe frequency and power of the requested period of vibration for the site. Water is typically jetted to aid the compaction process. The resulting void that develops is filled with clean sand or gravel that is compacted by the probe.
