 — This was attributed to pile settlement during cooling, leading to an increase in toe resistance due to compaction of soil below the pile toe. The increase and decrease of shaft resistance with ...

recent innovations in the equipment used in installing sand compaction piles. A drawback of the conventional SCP method is noise and vibration caused by the use of a vibro-hammer, thus adversely influencing the surrounding environment. As refinement, non-vibratory SCP method (commercially known as "SAVE Compozer method") has been developed ...

Vibro compaction is a ground improvement technique that densifies clean, cohesionless granular soils with a downhole vibrator.
