Earth Tech Vibro Compaction

vibro compaction

The Vibro Compaction Construction method is a compaction process for purely granular soils.

Particles of non-cohesive soil can be re-arranged into a denser condition under the influence of vibrations from a specially designed vibrator probe.

The action of the vibrator, usually accompanied by water jetting, reduces the inter-granular forces between the soil particles allowing them to move into a more compact configuration.

This process is used in fully saturated and very weak soils. Water jetting removes soft materials, stabilizes the hole and allows the sand backfill to reach the bottom of the vibrator. This is then compacted and interlocked with the surrounding soil.
