The Vibrolance® is a cylindrical hydraulic vibratory system, composed of a vibrator, an isolator and various extension tubes. The vibrator contains an eccentric that continuously oscilates, generating radial vibrations. These vibrations are used to penetrate the ground and then to treat the soil, according to the chosen ground improvement technique (vibro compaction or stone columns). 5 meter extension tubes allow the Vibrolance® to adjust to almost any treatment depth. Vibrolances can be equipped with a Bottom Feed System (BFS), for stone column applications. In this case, a stone tube and a stone tank with a stone gate, will be added to the Vibrolance®.

TOP FEED:

Stone columns «Top Feed Method» is the most cost-efficient ground improvement method. It requires the use of a free hanging vibrolance that penetrates the ground thanks to the lateral vibrations emitted by its tip. During penetration, the soil is laterally compacted by displacement, allowing the vibrolance to create the hole that will contain the stone column.
