Water

  • High pressure water breaks up solids and materials
  • Effective in any soil condition
  • In most cases, displaced soil needs to be removed for disposal
  • In most conditions, excavating is faster
  • Relatively clean – No dust control issues

Air

  • Compressed air breaks up soils and materials
  • Most effective in less compacted soils
  • Displaced soils can be used as backfill
  • Overall productivity can increase – no need to leave the dig site to refill water or dump soils
  • Can be messy – produces fair amount of dust
