The different Ground improvement methods are as follows:-
1. Mechanical compactions.
2. Dewatering techniques.
3. Chemical methods by using admixtures.
4. By using reinforcements.
Mechanical compaction
it changes the state of the soil from loose to dense state.
It is a long term improvement technique.
In this method the state of the soil gets changed.
This method is used for the silty, sandy and gravally soils.
Some of the tools or machines used for the mechanical compactions are as follows:-
Flat roller,vibratory roller for fine sand,etc.
For clayey soils mostly dewatering is prefered.
Admixtures or Grouting
In this Cementations plays a vital role in modification of the soil properties.
It can be short term or long term improvement techniques.
In this also state of the soil gets changed.
Reinforcement
It improves the soil response by interection between soil and inclusions.
Improving period depends on the life of inclusion.
In this change of state does not takes place.
It can be used for wide range of soil types.
