The process of soil stabilization refers to changing the physical properties of soil in order to improve its strength, durability, or other qualities.  Typically, this is important for road construction, and other concerns related to the building and maintenance of infrastructure.  Soil that has been stabilized will have a vastly improved weight bearing capability, and will also be significantly more resistant to being damaged by water, frost, or inclement conditions.

3 Types of Soil Stabilization Techniques – by Proven Experts

Different types of soil stabilization have been performed for thousands of years; it wasn’t too long after roads were developed that primitive engineers began looking for ways to improve them.  Believe it or not, some of the original methods (or at least their spiritual descendants) are still employed today.  Let’s take a look at the three basic types of soil stabilization and how they work:

  • Mechanical – The oldest types of soil stabilization are mechanical in nature.  Mechanical solutions involve physically changing the property of the soil somehow, in order to affect its gradation, solidity, and other characteristics.  Dynamic compaction is one of the major types of soil stabilization; in this procedure, a heavyweight is dropped repeatedly onto the ground at regular intervals to quite literally pound out deformities and ensure a uniformly packed surface.  Vibro compaction is another technique that works on similar principles, though it relies on vibration rather than deformation through kinetic force to achieve its goals.

  • Chemical – Chemical solutions are another of the major types of soil stabilization.  All of these techniques rely on adding additional material to the soil that will physically interact with it and change its properties.  There are a number of different types of soil stabilization that rely on chemical additives of one sort or another; you will frequently encounter compounds that utilize cement, lime, fly ash, or kiln dust.  Most of the reactions sought are either cementitious or pozzolanic in nature, depending on the nature of the soil present at the particular site you are investigating.
  • Polymer/Alternative – Both of the previous types have been around for hundreds of years, if not more; only in the past several decades has technology opened up new types of soil stabilization for companies to explore.  Most of the newer discoveries and techniques developed thus far are polymer based in nature, such as those developed by Global Road Technology.  These new polymers and substances have a number of significant advantages over traditional mechanical and chemical solutions; they are cheaper and more effective in general than mechanical solutions, and significantly less dangerous for the environment than many chemical solutions tend to be.


Are environmental regulations, health and safety concerns or potential profit loss a concern right now?

All three types are still employed on construction projects all across the globe, though the polymer-based solutions offered by firms like Global Road Technology are rapidly gaining ground due to the cost savings, ease-of-use, environmental benefits, and other significant advantages they bring to the table over more traditional soil stabilization types.
