Vibro Stone Columns for Ground Improvement | .

Vibratory stone columns, also known as vibro stone columns, vibro replacement stone columns, vibro-piers, or aggregate piers, are compacted columns of aggregate that are installed through existing soils to improve the geotechnical properties of the soil matrix. The stone columns consist of a series of vertical lifts of compacted aggregate from a predetermined design depth up to the ground surface.

Stone Column Method in Geo Engineering Projects

Stone columns are commonly installed by water jetting or air jetting cylindrical vibrating probes into the ground to form holes, which are backfilled with gravel or crushed rock densified by the vibratory probe as it is withdrawn from the ground. Water jetting is part of the vibro-flotation technology, which is often referred as vibro-replacement or wet, top feed method.

Roxborough Ground Improvement Vibro stone .

Vibro stone columns (VSC's) are a ground improvement technique which improves weak soils with the installation of densely compacted columns made from stone or aggregate via vibration. The vibrating vibroflot on the purpose built rig penetrates the ground until reaching the required design depth for the columns.

Environmental stone columns | Keller UK

When aquifers underlay made ground a stone column is sometimes perceived as potential path for contamination. In reality, vibro treatment reduces the mass permeability and so this is rarely an issue. However, in some cases it is necessary to seal the base of the columns. This is where Keller's Environmental Stone Columns (ESC) can provide the perfect answer.

Vibro Displacement Piling | Dawson Wam

Vibro stone columns (typically referred to as VSCs) are a very time and cost efficient method of improving the ground bearing capacity of softer soils and reducing differential settlement. Vibro stone columns can be installed quickly in suitable ground conditions and offer a viable option for industrial and commercial units, transport infrastructure and housing.

Like most ground improvement techniques, stone columns are used to reduce settlement and increase load-bearing capacity. They also accelerate soil consolidation as a result of the drainage capacity of the granular materials within the columns which act as pore or water pressure evacuation points.

What are stone columns - The Engineering .

Stone columns are constructed using down-hole vibratory probe methods similar to those used in vibro-compaction. The main difference is that instead of using coarsegrained soil to simply fill the void created by the vibro-compaction operation, stone or other clean, coarse grained materials are placed, and compacted, to form a narrow structural element (i.e. a column) which functions as one or ...
