Importance of bore hole in geotechnical engineering is following as:

1) Determination of the bearing capacity of the soil

2) Selection of type and depth of foundation capacity of the soil

3) Investigation of the safety of the existing structures and for necessary remedial measures

4) Selection of suitable construction technique

5) Calculation of the lateral earth pressure against retaining wall and abutments

6) Estimation of probable maximum and differential settlements

7) Predication and solving of potential foundation problems

8) Establishing the ground water table level and determine return of the properties of water

9) Determining the suitable of the soil as a construction materials
