Sand Compaction And Stone Columns Machines

  • Spike's Compaction Factor Calculator

    Spike's Compaction Factor can also be used to estimate the amount of material you need to purchase for an area that needs to be filled and compacted. For instance, you need to place a 6" layer of gravel inside a foundation. Your calculation of the area for a 20' x 20' wide with a depth of 6" would give you a volume needed of 20 * 20 * .5 = 200 cubic feet.

  • Vibroflotation (Stone Column) Equipment - Top …

    When a vibroflotation machine is driven into the loose ground, it creates a hole. Gravel particles of a certain size are then fed into the hole, either using the top feed or bottom feed method. A stone column is then produced by compressing the gravel with vibration. This increases the supporting strength of soft and loose grounds and reduces liquefaction risk. If you need further details ...
