For any construction project, whether it’s a building, a road or an airfield, the base soil acts as the foundation. Additionally, the soil is one of the crucial construction raw materials. As such, soil should possess properties that create a strong foundation.

What is Soil Stabilization?

It is a procedure wherein the engineering properties of the soil are altered and enhanced to increase its suitability for construction purposes. To put it in simple words, it is a method of stabilizing soils.

The practice of stabilizing soils dates back to the age of the Romans. Other nations such as the United States and China among many others adopted it in the latter half of the 20th century. There were several reasons for it. Not all sites offer favourable construction conditions. At such sites, a contractor usually has four main options at his disposal. They are:

  • Substituting poor grade soils with aggregates possessing more favourable engineering properties.
  • Looking for a new construction site.
  • Modifying the proposed structure to suit the poor engineering properties of the current soil.
  • Finally, enhancing the properties of soil on site.

Options 1, 2 and 3 are not only expensive but also impractical. Today, with better research and more effective equipment and materials, soil stabilization, option 4 on the list, is considered the most feasible option for all construction purposes. Some definitions of it also refer to the process as soil modification.

What are the benefits of Soil Stabilization?

Soil Stabilisation Methods:

When speaking about the definitions of it, it is important to consider the methods used for the same. Soils are stabilized either by subjecting it to mechanical processes or by adding a chemical or additive. Compaction is one of the commonly used mechanical processes. It increases the density of the soil by eliminating air from between grains. Soil that has been compacted has better load-bearing capacities and reduces porosity.

As far as the use of chemicals is concerned, lime, bituminous and cement are some of the additives added to the soil. These additives and binders when they come in contact with the pozzolanic minerals present in the soil or water, they react to form composite materials. Soil-cement is better known as a mechanical additive because like mechanical processes it does not alter the chemical properties of soil like lime would do, but simply enhances its existing properties.

The method of stabilizing soils is a commonly undertaken procedure in the construction of airfields, parking lots, landfills, embankments, roads and foundations, waterway management, agriculture and mining sites. The type of stabilization that might be used depends on the site; it may use single method or a combination of the two.

GRT Soil Stabilization:

Global Road Technology is a world leader in stabilization and dust control solutions.  The innovative range of products has revolutionized the definition of it in-situ by creating for environment-friendly construction projects. It holds the future of road stabilization and surfacing with its GRT9000 which when integrated into gravel, clay, silt and sand prepares hard, semi-flexible and water-impermeable surfaces.  Additionally, the GRT8000 and GRT5000 liquid trapping products are the preferred choices for dust suppression. They work like a dust palliative and a soil stabilizer simultaneously to trap fine soil particles before they can become airborne.

The Global Road Technology lineup also includes bonding and capping agents to create strong foundations, capping layers and road sub-base layers. If this is not enough reason, GRT products offer the longevity and stability that no other soil stabilization and dust suppression systems on the market can offer, all products have been tested extensively by the world’s leading environmental risk management company.

The Definition of soil stabilization can be explained by any number of our industry leading consultants.
