General Parameters & Advice

There is a broad spectrum of sites that can benifit from Soil Modification and or Soil Stabilization.  When any of the following circumstances are present, Soil Modification or Soil stabilization could be a viable solution.  

  • Wet/unstable soil that cannot be properly compacted due to high moisture content or high plasticity index (PI)
  • Soils with high shrink/swell potential
  • Unstable granular soils

Soil Modification/Stabilization can be used in new construction or in reconstruction to add structural integrety to poor quality subgrades. Soil Modification/Stabilization allows the in-place recycling of pavements with deep subgrade or drainage problems. Existing bound materials and aggregate base is typically moved to one side, the subgrade reworked or stabilized and the existing materials placed back on the prepared subgrade for further processing. 

Site Selection for Specific Distresses

Soil Modification and Soil Stabilization can address the following subgrade issues:

  • Subgrade instability
  • Excessive shrink/swell 
  • Excessive moisture
  • When used with FDR, CIR or CCPR Soil Modification and Soil Stabilization allows the treatment of distresses deeper in the pavement structure than the recycling/rehabilitation technicues can address alone

Road Type, Surface, and Traffic Specifics

high traffic area

Soil Modification and Soil Stabilization are versitile processes and have been successfully utilized on all road types and traffic, including city streets, county roads, interstate highways, parking lots, industrial storage facilities and airports. 


There are no climate restrictions for Soil Modification or Soil Stabilization, they have been used successfully in all climate zones including wet freeze, dry freeze, wet no freeze and dry no freeze. There are weather restrictions during construction that vary depending on the modifying/stabilizing agent used. See Weather Requirements for more information.
