General Rock Excavation

Image for Cardox Civil ApplicationsExcavation of 10,000m³ of hard granite in a busy town in New Hampshire U.S.

Explosives were prohibited due to:

  • Fear of nitrates penetrating underground spring and walls
  • Shock waves and vibration effecting surrounding houses, shops & roads
  • High noise levels
  • High dust levels

Hydraulic rock breakers were not considered due to:

  • The considerable duration to break the granite
  • Exorbitant costs involved
  • Increased and continuous noise

The Cardox System is extensively used for breaking rock and concrete with complete safety and without any adverse effects. Cardox produces instantaneously a powerful heaving force using CO2 which cracks and breaks the rock or concrete.
