Soil improvement in its broadest sense is the alteration of any property of a soil to improve its engineering performance such as strength, reduced compressibility, reduced permeability, or improved ground water condition. This may be either a temporary process to permit the construction of a facility or may be a permanent measure to improve the performance of the completed facility.

Techniques of Soil Improvement

There are various techniques used for the improvement of the soil based on the construction activity and type of soil. The soil improvement techniques are:

1. Surface Compaction

2. Drainage Methods

3. Vibration Methods

4. Precompression and consolidation

5. Grouting and Deep Soil Mixing (DSM)

6. Chemical Stabilisation

7. Soil Reinforcement

8. Geo textiles and Geo membranes

9. Other Methods
