Cement-Fly Ash-Gravel (CFG) Pile
Cement-Fly Ash-Gravel Pile or CFG Pile was developed based on stone column. When the stone column is applied in soft soil conditions, stone column is not reliable due to the confine resistance is relatively low…

Stone Column (Vibro-replacement) is a combination of vibroflotation with a gravel backfill resulting in stone columns, which not only increases the amount of densification, but provides a degree of reinforcement and a potentially effective means of drainage…
