Vibro stone columns provide a quick, cost-effective foundation solution and a practical alternative to traditional piling or deep trench fill. As a displacement technique, they generate minimal spoil.
The process involves penetrating a vibroflot to the design depth, creating a bore that is backfilled with primary or recycled aggregate and compacted in stages to form a dense, interlocking column. In granular soils, the vibration increases ground density, while in cohesive soils the columns act as reinforcing elements, improving settlement performance.
