Chemical stabilization of soil improves the strength parameters of soil and increases its bearing capacity in road construction. New techniques in this process help companies prevent the costly problems of soil erosion.
What Is the Chemical Stabilization of Soil?
Simply put, chemical stabilization of soil involves adding chemicals to the soil to change the soil structure. This process helps make it stronger by binding soil particles together. Once roads have been treated with chemical stabilization, they are less likely to have dirt washed away due to wind and water erosion.
Why Soil Type Matters
There are four main types of soil: loam, silt, clay, and sand. Each of these soil types has different characteristics and needs when being stabilized. Before you decide what chemical soil stabilization method to use, check your soil and see which way best interacts with that soil type.
Chemical Stabilization Methods
There are several chemical stabilization methods, all of which alter soil properties such as strength, compressibility, hydraulic conductivity, and volume. Choose from these top methods which will be best for your next construction project.
A popular choice for chemical soil stabilization is chlorides. Chloride is a salt-based inorganic compound that can bind dust particles. Calcium chloride and magnesium chlorides are commonly used. The decision to use one or the other is often due to availability. Chlorides are cost-effective and have been in use for decades for dust control.
Polymer products are considered one of the best choices for the chemical stabilization of soil. Polymer soil stabilization can help prevent soil erosion and improve water infiltration. Acrylic polymer soil stabilizers, such as Envirotac, improve the physical properties of soil by binding soil particles together much like glue. This process increases the soil’s compression strength, volume stability, and load-bearing capability.
Lime and Cement
Lime, or cement, soil stabilization is done by mixing lime or cement into the soil to increase its resiliency and strength. The amount of lime or cement mixed in varies depending on the soil type and its qualities. While it can be costly, this method is versatile and is compatible with almost every soil type.
The Top Choice for Your Next Construction Project
To choose the best treatment for chemical soil stabilization on your next project, consider the type of soil, the project type, the length of the project, and your budget.
