Valuable Facts In Chemical Soil Stabilization

By Lelia Hall


The prime objective of soil stabilization is to improve the weight bearing capacity of the sub-soils and other materials used in the construction of roads and house foundations. This forms a durable framework that supports such constructions. Previously, the process of chemical soil stabilization was done by the use of cement and lime, but now greener methods have been discovered.

This project is labor intensive thereby, you have to recruit a group of committed specialists who can perform well. Furthermore, there are specific appliances which are necessary to turn the layers of the subsoil and also hardened them once the chemical compounds are added to develop a homogenous blend. You ought to make sure that the appliances are available just before you start the venture.

In foundation bases of buildings you might be required to use cement or lime. You are recommended to use cement as it is cheaply and readily available. However, lime is quite expensive due to the cost of burnt limestone required in the process and it is not environmentally friendly. This is on account that burning lime in high temperature kilns generates toxic effluents that can affect the ground water supply.

The primary objective of this approach is to enhance the overall performance of sub-soils and sand soils for development applications. Nevertheless, you might fail to accomplish this aim in the event you carried out the undertaking when the weather conditions were unfavorable. A few chemical compounds are influenced by moist conditions. Subsequently, you should check with suitable meteorological officers and determine the time when the climatic conditions are favorable.

Time for curing and also setting could vary depending upon the sort of admixtures used. That is why, you have to study the manual given. In case anything is confusing, you at all times can communicate with the producer through the contact information posted on the bill. As an alternative, consult a specialist. She or he would offer ideal strategies relating to the ideal season when you might carry on with your venture.

The use of polymeric materials is yet another method commonly used today. It entails mixing the subsoil with neutral, non-reactive polymers. It is quite advantageous as the materials are not as harmful to the environment, however, creates a waterproof semi flexible pavement. The materials are also quite beneficial in terms of strength as well as cost.

Prior testing should be done to determine whether the ground really needs stabilization or not. Perhaps the ground is stable and simple compaction can help achieve the required strength. Even after the application of the necessary admixtures, laboratory tests should be carried out to assess whether there was any significant improvement. If not, the process should be repeated and if possible, try to apply other materials that can help improve the binding factor as well as the compressive strength of the soil.

Whenever large development ventures are to be established, the soil profile must be properly designed to refrain from irregular settlement. This could aptly be achieved through the use of specific inorganic additives as well as a mixture of supplementary elements which can help enhance the profile. Give it time to set as well as cure prior to when you continue with your undertaking.
