Vibro Concrete Columns from Keller Group are not the kind of product you see on a shelf, but you can feel them under your feet when you stand beside a newly widened highway ramp and the ground feels rock-solid instead of spongy after rain.

How Vibro Concrete Columns work

Vibro Concrete Columns, or VCCs, are Keller’s ground improvement solution where a vibrating poker compacts soil while concrete is fed down a casing to form stiff columns in weak ground.

The method targets soft cohesive soils and loose granular layers, transferring loads from pavements and foundations into deeper, stronger strata so structures can sit on improved ground instead of full deep piles.

US projects and on-site feel

In the U.S., Keller uses Vibro Concrete Columns under highway interchanges, logistics hubs and rail corridors where poor soils would otherwise force more expensive deep foundations.

On a recent Midwestern distribution center job, site engineers described how the rig’s steel mast vibrated with a low, steady hum as concrete flowed, and the freshly treated pad felt firm even after a thunderstorm.

Design, capacity and use cases

VCCs are typically installed in diameters around 400 to 600 millimeters, with spacing and layout tailored by Keller’s geotechnical engineers to match the expected loads and soil profile.

Each column can carry significant vertical load compared with untreated soil, making the system well suited for slabs-on-grade supporting heavy racking, tank farms, or traffic loads without the need for individual pile caps.

What investors should note

For investors, the key point is that Vibro Concrete Columns are a repeatable service product embedded in Keller’s broader ground engineering offering, generating revenue across thousands of infrastructure and industrial projects rather than a single flagship structure.

Shares of Keller Group (LSE: KLR) trade in pounds on the London Stock Exchange, with no direct U.S. listing, but the company’s U.S. projects using systems like Vibro Concrete Columns contribute to its international earnings base.
