A Rapid and Cost-Efficient Approach to Ground Improvement

Controlled Modulus Columns (CMC)® are concrete columns placed in a grid network that effectively spreads the applied high loads from the structure above and between the ground and the grid of CMCs. CMCs are often mistaken for other deep foundation solutions, such as conventional auger-cast-piles or drilled caissons. Those piling systems are designed as structural elements, unlike CMC’s unique installation that results in stiffened soils capable of supporting shallow footings and slab-on-grade.

  • Zero-spoils: No excess soils to remove
  • Minimizes differential settlement
  • Vibration-free displacement process
  • Soft soils 
  • Organic clays 
  • Loose sands 
  • Treat soils up to 50m deep 
  • 280-500mm-diameter elements installed 

CMCs are installed by advancing the displacement tooling to the target depth and filling with cement-based grout as the tooling is retracted – grout is discharged at the base of the hollow tooling under controlled, and limited pressure to ensure the continuity of the grouting process. CMCs have been installed to depths of over 45 m. 

How it Works

CMCs work by utilizing reverse flight augers to effectively displace the soil laterally, significantly densifying the soil around the CMC, which in turn improves the load transfer to the installed element; essentially, they draw in the load from above and transmit those forces downward into more competent soils below. The combined effect of reinforcement and densification from the installation process improves the characteristics of the ground, resulting in a composite system. The load from the structure is then distributed to the soil and CMCs, with the proportion of the load carried by the soils. Depending on the stiffness of the soil, the stiffer the soil is, the higher proportion of the stresses will be carried by the soil. Typically, a layer of compacted stone known as a Load Transfer Platform (LTP) is designed to span across the top of the CMCs to help distribute the load from the structure to the elements.
