Vibro-compaction (for ground improvement)
GÉOTUBE Notre entreprise- Nos services- Nos forces

The GeoTUBE® allows the densification of granular soils, from the surface or from barges, with a probe generating vibrations along the vertical axis.

The technique is used to densify soils through the insertion of a large diameter hollow steel tube with a powerful vibrating hammer. Essentially, it is a vibro-densification process similar to Vibroflotation, except that the vibrations are vertical rather than horizontal. The source of the vibration is located at the top of the tube, whereas with Vibroflotation the source is at the bottom of the probe. The GeoTUBE® is an adaptation of the technique generally referred to as %u201CTerraprobe%u201D where pressurized water is added at the tip and inside the tube during the operations to improve the density of the soils treated.
The GeoTUBE ® can improve granular soils to depths reaching 10 to 12 metres (40 feet). Where the water table is near the surface, this process does not require the addition of water and does not reject soils to the surface which, in some instances, may prove advantageous for environmentally sensitive soil conditions.
