Impact compaction

Dynamic soil compaction
Schematic illustration of the dynamic soil compaction:
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
For impact compaction a heavy tamper weight is dropped from heights of up to 40 metres onto the ground to be compacted. This dynamic input of energy increases the density of the building ground. The craters created through impact compaction are refilled with suitable material and further compacted, if necessary. Duty cycle crawler cranes of the HS series carry out the compaction process efficiently and automatically with free-fall winches and crane control.
