Vibro Compaction
Vibro compaction is a ground improvement technique that densifies granular soils using a downhole vibratory probe. The probe is lowered vertically into the soil, typically with a standard crane. After reaching the bottom of the treatment zone, the soils are densified as the probe is raised. The vibratory energy allows the soil particles to move into a denser configuration. The densification results in a depression at the ground surface unless granular backfill is added during the densification process. The treated soils have increased density, friction angle and stiffness. The technique has been used to increase bearing capacity, decrease settlement and mitigate liquefaction for planned structures, embankments, railways and roadways.
