Dynamic compaction is a cost effective and efficient site improvement technique used to densify loose fills to facilitate the construction of shallow foundations.

Common Uses

  • Improve bearing capacity
  • Reduce settlement
  • Reduce sinkhole potential
  • Reduce liquefaction potential

Technical Details

Dynamic compaction uses a drop weight to densify loose or disturbed soils and other materials. Soils are densified at depth by the controlled impact of a crane-hoisted, heavy weight (15-35 tons) on the ground surface in a pre-determined grid pattern. Dynamic compaction is also successful in densifying landfill material for future construction.
