This is a critical process to ensure successful vibrocompaction implementation. The penetration depth records can be used to ensure the vibrocompaction is reaching the desired depth. The penetration and withdrawal rates can be used to confirm that an acceptable duration of time is spent densifying the soil. It is necessary to confirm that the appropriate number and spacing of vibrocompaction points are completed, which are specifically designed to achieve the desired improvement. It should also be verified that appropriate equipment is used during implementation.</p></p>
