CONCLUSION
INTRODUCTION
Used to reinforce and strengthen existing ground.
Installing closely spaced bars into a slope or excavation.
It is an effective and economical method.
Act as a retaining wall for excavation support.

ADVANTAGES
Shotcrete facing is less costly
Grouting only once is required, saving time and labor.
The technique is flexible, easily modified.
Less impact on nearby properties
Can be used for strengthening of either natural slope, natural or man-
CONCLUSION
Soil nailing is a potential solution of landslide problems.
Economical and also applicable in seismic zones.
It can be used in wide soil types.
