Vibro-flotation involves driving a vibrating probe into the ground, generating lateral forces that rearrange soil particles into a denser state. Water is often used to assist penetration and densification, while backfill is added to further enhance this process. This method improves the bearing capacity and settlement performance of existing soils, enabling the use of standard shallow reinforced foundations further reducing the overall costs. Vibro-flotation is particularly effective for constructing on large areas of weak ground.
Vibro flotation is a ground improvement technique that can be used in the residential, commercial and industrial sectors and infrastructure, including:
The vibro compaction technique is well established for use in
- Tank farm
- Port and marine structures
- Large industrial units and warehouses
- Reclamation projects
- Pipelines
Advantages of Vibro Flotation method:
- Reduces foundation settlement
- Increases bearing capacity, allowing reduction in footing size
- Permits shallow footing construction
- Increases Stiffness
- Increases shear strength
- Can reduce permeability
- Mitigates liquefaction potential
- Provides slope stabilization
- Permits construction in fills
- Prevents earthquake-induced lateral spreading
The Vibro Compaction technique is best suited for loose sand to coarse-grained soil with a silt/clay content of less than 10% (less efficient with a fines content between 10% and 15%). The technique applies to depths up to 45m (or more, depending on the crane capacity).
