Where to Apply Soilcrete: A Stabilization Option

We have already got an idea about soilcrete. Now we will learn where this method should be used as Soil stabilization options. It is very uncommon to have a building site of having geotechnical and geological conditions in favor of structural and geotechnical design of building and most of times the engineers find a mitigation option to safely transfer structural loads to the ground. In case of ideal soil condition like dense sand or gravel, we need not to think about soilcrete. A simple foundation like column footing or hardly combined footing is safe for it with any application of stabilization.

The geotechnical engineers is afraid of the earthquake induced settlement due to liquefaction or from other causes of settlement in loose or soft soil deposits beneath the structure to be founded. The safest way is to transfer loads to stronger stratum for such type soil.

Like above method another safe method is to replacing soft and poor engineering quality soil with ideal soil sated above with designed percent compaction of this ideal soil. We discussed about percent compaction in previous post. Please follow this link above to have ideal about it.

In many situations the construction cost of piling/drilling shaft/replacing soft soil, is not feasible considering benefit-cost relationship and in some situations they are not also practical considering difficulties of construction. Soilcrete can effectively solve the problems of settlement hazards and bearing capacity failure, with a low cost involvement. This method also saves valuable construction duration in compare to conventional deep foundations or replacement options.
