Dynamic soil compaction

1. Positioning of the drop weight over the compaction point

2. Lifting the drop weight to the drop height

3. Free fall of the drop weight onto the compaction point

4. Lifting the drop weight for the next blow

5. Filling the compaction crater and grading the area

1 Compaction crater

2 Fill (e.g. stable gravel)

3 Effective range of the compaction

4 Soil with insufficient load bearing capacity

5 Load-bearing layer

Specially designed tamper weights allow for compaction work under water. Here, the machine is used on a barge.
