Some case histories of densification of loose sandy soils using compaction piles are analyzed. The sandy soils were improved to support heavily loaded structures using shallow foundations. The technique used was deep compaction through compaction piles driven with Franki-type equipment, and shallow compaction by vibratory plate. Results of the compaction processes are presented and discussed to provide guidance for future projects. The analysis includes distance from the compaction pile, initial relative density, time delay for results verification after compaction, and depth. The results of densification demonstrate the method is efficient.
