We know that whatever the structure we want to build, it finally have to put on the ground and the total load coming on the structure may be due to wind, earthquake or with any other combination of load that final will be transferred to the ground.

Now we often found that the soil is not sufficiently strong to carry the load coming from the structure that maybe a single storey building also.

It is often found that the existing soil is not capable of taking load from a single story building but still geotechnical engineering a branch of civil engineering find lot of solution in that respect in the way of ground improvement

If the soil doesn’t have sufficient bearing capacity or high settlement then there is a way to improve the bearing capacity of the soil and also to reduce the settlement under the loading.

Normally for any type of structure, we may have to choose shallow Foundation or deep Foundation, depending on the load of the proposed structure. Excluding this there are different types of techniques to improve the bearing capacity of the soil and also to reduce the compressibility of the existing soil in the following ways:
