Soil Stabilization

Experts in Soil Stabilization

Soil Stabilization is the permanent physical and chemical alteration of soils to an area or entire site that enhances their physical properties to improve the load-bearing capacity of sub-grade soil and support pavements and foundations placed on top. Stabilization can increase the shear strength of a soil and/or control the shrink-swell properties of soil.

Soil Stabilization can be utilized on roadways, parking areas, site development projects, airports, and many other sites where sub-soils are not suitable for construction. Stabilization can be used to treat a wide range of sub-grade materials, including clays and more granular materials. The process is accomplished by using a wide variety of additives, including lime, fly-ash, Portland cement, lime-kiln dust (LKD), and cement kiln dust (CKD).

Proper design and testing is an important component of any stabilization project. This allows for the establishment of design criteria and helps determine the proper chemical additive and admixture rate to be used to achieve the desired engineering properties.

Another form of soil treatment closely related to soil conditioning is soil modification, sometimes referred to as “mud drying” or “soil conditioning.” Although some stabilization inherently occurs in soil modification, the distinction is that soil modification is merely a means to reduce the moisture content of a soil to expedite construction and land development. 

Alternatively, Soil Stabilization can substantially increase the shear strength of a material such that it can be incorporated into the project structural design


  • During site and land development, soil stabilization services are often needed.

  • In addition to strengthening your soil base, improving compaction, and reducing plasticity, soil stabilization lowers permeability in certain types of soil, can reduce your future pavement thickness, eliminates excavation, material, hauling and handling, and base importation,
    and provides “all-weather” access onto and within project sites.

  • Soil Stabilization uses the same type of equipment used in Full Depth Reclamation. The main differences are FDR is used primarily on improved roadways and un-improved roadways, whereas Soil Stabilization is used on new virgin construction, site development both residential and industrial.
