Vibro compaction
During vibro compaction, clean sand backfill is typically added at the ground surface to compensate for decreased soil volume from the densification process. The vibratory energy reduces the intergranular forces between the soil particles, allowing them to move into a denser configuration, typically reaching a relative density of 70 to 85%.
