    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.

    Static force is simply the deadweight of the machine, applying downward force on the soil surface, compressing the soil particles. The only way to change the effective compaction force is by adding or subtracting the weight of the machine. Static compaction is confined to upper soil layers and is limited to any appreciable depth.
