3 Soil Stabilization Techniques and when to Use Them
- Chemical Stabilization - Chemical stabilization involves adding chemicals, such as cement or lime, to the soil to enhance its strength and stability. Typically, this technique is used on soil with high clay content, as it can help to bind the soil particles together. Chemical stabilization can also improve soil with a low bearing capacity or needs to be waterproofed. For example, a construction company might use a lime mixture to stabilize soil before building a foundation for a new structure.
- Polymer Stabilization - In this method, polymers, such as asphalt emulsions or acrylics, are added to the soil to increase its strength and reduce erosion. Construction teams typically rely on this method when working with soil with high silt or sand content, as the polymers can help bind these smaller soil particles together. However, polymer soil stabilization can also be used on soil with high clay content, improving the soil's ability to drain water. You'll often see polymer stabilization applied to soil that needs to resist deformation and fatigue, such as on roadways or runways. This type of soil stabilization is gaining popularity across the globe due to its ease of use, cost savings, and environmental benefits.
- Mechanical Stabilization- Mechanical stabilization involves physically altering the soil through compaction, mixing, or reinforcing with materials such as geogrids or soil nails. This technique is often used on soil with high moisture content or a mix of soil particle sizes. Mechanical stabilization can also improve the soil on embankments or slopes to prevent soil erosion. For example, a construction team might use soil nails to reinforce soil on a steep slope before building retaining walls or installing landscaping. However, this method can be labor-intensive and may require heavy machinery.
Which Soil Stabilization Method Is Best?
Each soil stabilization method has its own benefits and drawbacks, and it's essential to carefully consider the project requirements before deciding on a technique. In some cases, it may be necessary to use a combination of soil stabilization techniques to achieve the desired result.
