In the video, A bulldozer pulls paired "plum-flower hammers" (impact rollers) to compact a 1.5-meter-thick soil layer in one pass.
Key notes:
This method attempts deep compaction in a single lift, but full depth effectiveness is hard to achieve.
For optimal soil density, layered compaction (filling & compacting in thinner stages) is recommended.
Using thinner layers ensures uniform density and reduces settlement risks.
