Controlled Modulus Columns™

The Controlled Modulus Columns™ are well adapted to high surface loading conditions and strict settlement requirements and are used to support slabs-on-grade, isolated footings and embankments on compressible clays, fills and organic soils.

A specially designed auger, powered by equipment with large torque capacity and high static down thrust, displaces the soil laterally, with virtually no spoil or vibration. During the auger extraction process, a column is developed by pressure-grouting to achieve a predetermined stiffness ratio with the surrounding soil. The result is a composite soil/cement ground improvement system.

Advantages of Controlled Modulus Columns:

  • Uniformly supports slabs-on-grade, thus reducing the required slab thickness and reinforcing steel quantity
  • Increases the strength properties and modulus of the in-situ soil
  • Displaces soil laterally, with virtually no spoil, thus no need to dispose of contaminated soil
  • Reduces vibration and minimizes disturbance of the surface layer
