Many of us simply never think about the ground that we walk on each day.
However when you stop to think that everything from your home to your car to your child’s school is sitting on foundations in the ground, it makes you realise just how important the stabilisation of soil really is.
What Is Soil Stabilisation?
The term ‘soil stabilisation’ refers to the process in which the physical properties of soil are changed. This is generally done to improve its strength and durability.
By stabilizing soil, it has an improved weight bearing capacity and is more resistant to water damage or extreme weather conditions.
Far from being a newly devised process, soil stabilization has occurred in various forms for thousands of years.
When Is Soil Stabilization Used?
According to Urathane Solutions, soil stabilization is often essential for road construction and when considering the building and maintenance of other infrastructure. Soil stabilization is often used in areas where there are extreme weather conditions such as significant rainfall, drought or very cold temperatures.
What Are The Different Types of Soil Stabilization?
This is the type of soil stabilization most traditionally used. It involves physically changing the property of the soil in order to affect its gradation and solidity. There are a variety of mechanical soil stabilization techniques including:
- Dynamic Compaction – this is when a heavy weight is dropped over and over onto the ground in order to pound out deformities. At the end of the procedure, the surface is uniformly packed.
- Vibro Compaction – this uses vibration through kinetic force to achieve a uniformly packed surface.
This type of soil stabilization is when additional materials are added to the soil in order to change the properties via a chemical reaction or interaction.
Chemical soil stabilization has happened for many hundreds of years and developed greatly in recent decades. Additional materials added to soil can include:
- Fly Ash
- Kiln Dust
This is the newest type of soil stabilization and the process relies on polymers and other substances that are often cheaper and can be more effective than older methods.
Many advocates for polymer soil stabilization also point to the lower risk these pose to the environment compared to chemical processes. More information can be found on this website.
