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.

If you are to make the soil stable in your construction site then you should use any of these materials and methods.

Let us look first at the different stabilization materials.

You use slaked lime in highly plastic or clay-like soil. When adding slaked lime, the soil is strengthened and stabilized. The soil becomes more compact since it helps to remove water from the soil.

Cement is a popular stabilizing material for soil. Whatever types of soil you are working on, you can use cement to stabilize it. Stabilization is improved if you add lime, sodium sulfate, or fly ash to 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.

The stability of the soil can also improve by adding chemicals. The most popular chemicals include calcium chloride, sodium chloride, and sodium silicate. These help the soil to compact and make it more stable. Particles stick together better because water retention is increased.

Fabrics or geotextiles can be used in building up of the soil. Geotextiles are porous and you have different options depending on the type of soil you are working with.

EnviroGrid made by Geo PRoducst is one popular example of geotextile. These heavy duty cells prevent the filler material from lateral movement. Because of their excellent drainage, they can be used in wet areas.

Here are some soil stabilization methods you can use.

One of the common method of stabilizing soil is by mixing in the stabilizing materials. The correct percentage of additive should be mixed with the amount of soil you have.

Soil depth is another issue. It is important to have enough depth for the materials to do their job. If the earth is loose, then a deeper mixture of stabilizing materials is required.

Grouting is a more expensive option for soil stabilization. This is used in buried areas of the earth which does not allow mixing it with the materials. Stabilizers are injected into the soil where it permeates and mixes to make the soil stronger and more compacted.

An expensive method of soil stabilization is electrical stabilization. Clay-like soil can use the method of electrical stabilization. Metal electrodes are inserted into the earth in this stabilization method. Then a current is run through them and water moves toward the electrodes. The soil becomes more compact when water is removed from it. The safety of construction vehicles is ensured with more sturdy
soil.
