Project Description


Controlled Modulus Columns – Rigid Inclusions

Where traditional ground improvement techniques may not be suitable due to either poor soil strength, high loadings or tight settlement criteria, controlled modulus column rigid inclusions (CMCs) provide a fast and economical ground improvement alternative to piling.

The technique installs low strength concrete columns, 280mm to 500mm in diameter, up to 50m in depth using our displacement tools.

Controlled Modulus Columns


  • Suitable across a range of soil types including soft to very soft organic clays
  • Enhanced bearing capacity

  • A reduction in the total and differential settlements

  • Ground bearing foundation solution utilising a distribution mattress

  • The rig working platform can be used as part of the distribution mattress

  • No breaking down of CMCs. Trimming is undertaken while the CMCs are still wet

  • The vibration free displacement process creates minimal spoil


  • Heavily loaded commercial/industrial floor slabs
  • Road and rail embankments

  • Silos, tanks and wind turbines

  • Residential buildings traditionally founded on driven piles
