Vibro Compaction
The Vibro Compaction Process
This process is used in fully saturated and very weak soils. Water jetting removes soft materials, stabilises the hole and allows the stone backfill to reach the bottom of the vibrator. This is then compacted and interlocked with the surrounding soil.
Vibro Compaction Construction method. This is a compaction process for purely granular soils.
It relies on the fact that particles of non-cohesive soil can be re-arranged into a denser condition under the influence of vibrations from specially designed poker vibrators.
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.

After a certain compaction time, the particles are arranged in such a way that the optimum density has been achieved.
Keller's Vibro Compaction process ensures permanent densification above and below the water table. Tidal variations and natural changes in ground water level do not adversely affect the stability of the densified granular soil.

Vibro Compaction has been used to achieve in-situ densification of loose sands to depths in excess of 30 metres.
