Vibro Compaction Hayward Baker

Compaction is achieved above and below the water table. The improved soil characteristics depend on the soil type and gradation, spacing of the penetration points, and the time spent performing the compaction. Generally, the vibro compaction penetration spacing is between 6 feet and 14 feet, with centers arranged on a triangular or square pattern.
