What is Soil Stabilization?
Soil stabilization is a process by which a soil’s physical properties are transformed to provide long-term permanent strength gains. Stabilization is accomplished by increasing the shear strength and the overall bearing capacity of the soil.
There are three broad types of soil stabilization: biological, physical, and chemical.
- Biological Soil Stabilization- This is achieved through afforestation or planting, and its main purpose is erosion control. This method suits terrain exposed to water and wind influences, which are not meant for building.
- Physical Soil Stabilization- It is the modification of soil particle size distribution and plasticity by the addition or subtraction of different soil fractions in order to modify its physical properties. Mechanical stabilization is the modification of soil porosity and interparticle friction or interlock.
- Chemical Soil Stabilization- It can be achieved using traditional and non-traditional agents. Examples of traditional chemical stabilization agents include lime, cement, bitumen, and fly ash and they are usually calcium-based.
