Tips On Chemical Soil Stabilization

By Claudine Hodges


This is the process that is used to enhance the engineering properties of soil in order to improve its stability. Chemical soil stabilization usually entails the use of chemical components in enhancing soils. Stabilizing soils is necessary whenever the available soil for construction is unsuitable for the needed function. It usually entails compaction, drainage and preconsolidation among other processes.

An overview at some of the specific methods used in making the soils stable, their benefits and disadvantages are explained later in this article. In addition, reasons as to why global road technologies and polymer-based admixture program are of superior level for various applications are also noted. Among the most commonly methods that are used to stabilize soils all over the world include;

Cement stabilization - It is a highly common procedure that is used in soil compaction. It is adopted mainly due to its cost effective nature and the availability of cement in almost any place. These soils are mixed and combined together with cement to boost its strength and robustness. Final results usually are fair and durable and also resistant to different weathers making this method an ideal choice for sandy environments.

This process however is relatively intensive on labor and may also be harmful to the environment. To add onto this, while the soil cement mixture that is resulted is highly durable, it is sometime also still susceptible to getting cracks.

Lime stabilization - It is yet another very popular method is stabilizing soils. The procedure is usually not nearly cost effective as compared to cement. What actually makes it expensive is the cost of burning limestone that is required in the process. It is also harmful to environment. It however does not increase the strength and soils stability especially in dry environments where materials can be compacted. The compressive strengths ought to be increased in some situations.

Chemical stabilization - They are of a wider group since there are numerous applications that are different. The main advantage of this approach is the possibility of designing a solution that can be specific for any given environment that you will be in need. Consequently, this leads to higher performance and reliability of the approach. Most of the used chemicals in the process are pollutants and they are also costly to acquire.

Polymer stabilization - The polymer based methods are the most up to date methods. They do present various advantages over the more traditional methods. They usually involve combining the soils with unreactive, environmentally friendly polymer based materials. One great advantage of these methods is that they fail impact the environment negatively while also creating waterproof, semi flexible pavements. Advantages are offered in terms of strength and also by being very affordable options.

Based on the above, it turns out clear that several benefits are presented by each method. Majority of them are cost effective, less prone to physical damage, durable, easy to maintain and may be used in correct proportions to maintain healthy environment. Innovative products can be employed to boost properties of the methods in order to get ideal final products.
