Quick Answer: What Is Deep Dynamic Compaction
What is deep compaction? Dynamic compaction is a ground improvement technique that uses a drop weight to densify loose soils. Soil densification is carried out by the repeated, controlled impact of a heavy weight (10-40 tons) on the ground surface. Vibrations are generated for a considerable lateral distance.
