Different Soil Stabilization Materials and Method.
When soil is poorly stabilized, it often leads to excavation accidents which kill construction workers. However, this should not be the case if the worksite soil is very stable enough to operate machinery in minus the risk of cave-ins.
Below are some of the materials and methods that can help stabilize the soil in a construction site.
Let us look first at the different stabilization materials.
You use slaked lime in highly plastic or clay-like soil. Strengthening and stabilization of the soil happens when slaked lime is added to it. Since water is removed from the soil, it becomes more compact.
Cement is a popular stabilizing material for soil. Whatever types of soil you are working on, you can use cement to stabilize it. To improve stabilization, other materials such as sodium sulfate, lime or fly ash can be added to the cement.
Bituminous materials such as asphalt and tar can give coherence to the soil which reduces the absorption of water and improves stability. Using these materials can prevent soil erosion.
You can add chemicals to the soil to improve stability. The chemicals used include calcium chloride, sodium chloride, and sodium silicate. Using chemicals can help compact the soil to stabilize it. Water retention is increased so for the better sticking of particles together.
Geotextiles are fabrics used in the stabilizing the soil. There are different kinds of porous geotextiles and it will depend on n the type of soil to determine the best option.
A good example of geotextile is the EnviroGrid manufactured by Geo Products. The lateral movement of your filler material is prevented by these heavy-duty cells. Because of their excellent drainage, they can be used in wet areas.
Here are some soil stabilization methods you can use.
In soil stabilization’s most common method, the stabilizing material is mixed in the soil. You should mix the additive in the correct percentage with the quantity of soil there is.
Another concern is soil depth. The materials can only do their job if the depth is enough. If the earth is loose, then a deeper mixture of stabilizing materials is required.
An option for the stabilization of soil which is expensive is grouting. If the soil does not allow material mixing, then grouting should be used. A more compact and stronger area is created by injecting stabilizers into the soil where it permeates and mixes.
An expensive method of soil stabilization is electrical stabilization. if the soil is clay-like then the best method of soil stabilization is electrical stabilization. In this method, you insert metal electrodes into the earth. Water moves to the electrodes you run current through them. Water is then removed and the soil compacts. Construction vehicle will then work on a more sturdy foundation.
