For many years this process has been used to achieve ground compaction and consolidation to considerable depths - providing a suitable base on which to support structures.

VIBRO projects’ method of operation is used with non-cohesive soils such as sand or gravel. Compaction occurs by simultaneous vibration and saturation.

The VIBRO Projects Bottom Feed Stone Column system provides high production rates of 400 to 800m per shift. The technique utilises a hollow steel tube driven into the ground by a top mounted hydraulic vibrator. The vibrator is driven from a power pack mounted on the rear of the machine.
