Home → CO2 rock breaking
No vibration. No shock wave. No noise. No fly rock. No blasting licence. For every excavation where conventional blasting is restricted, delayed or banned outright.
Across India, infrastructure, mining and urban projects stall the moment they hit hard rock and discover that blasting is not permitted — too close to a structure, too close to a road, vibration limits in force, or the licensing simply will not come through in time.
The Cardox System breaks rock and concrete using nothing but liquid CO2. It is classified as non-explosive, which changes the entire regulatory picture: no special permits for storage, use or transportation, and no magazine to build or guard.
How it differs from an explosive. An explosive shatters through a detonation shock wave. Cardox produces a controlled heave — pressure begins at the back of the hole and pushes forward, fracturing the rock along its natural planes without shattering it. That is why the material comes out in large clean lumps rather than fines.
Excavation adjacent to live roads, buildings and services where vibration limits rule out blasting.
Breaking out tunnel sections in hard and medium rock, including metro and highway works.
Rock trenches for services and pipelines in built-up areas.
Shafts excavated next to main roads and beneath live gas, electricity and water mains.
Hard rock removed from foundation footprints without shaking the neighbouring structure.
Controlled demolition of mass, lightly reinforced and heavily reinforced concrete in sensitive locations.
General quarrying and dimensional stone extraction — two tubes will split and heave a block of over 50 tonnes.
Harbour deepening and widening, seabed excavation for cable and pipeline routes, riverbed deepening, breaking concrete overspills.
Opencast and underground coal and ore — safe in gaseous mines, producing large clean lump product.
Planning figures for estimating tube counts. Actual yield depends on strata, burden, hole pattern and free-face conditions — we confirm against your geology before quoting.
| Application | Strata type | Average yield per tube (m³) |
|---|---|---|
| Quarrying | General | 3 – 6 |
| Dimensional stone | 5 – 20 | |
| General open-cut excavation | Hard / medium rock | 3 – 5 |
| Foundation excavation | Hard rock | 0.75 – 1 |
| Medium rock | 1 – 1.5 | |
| Trench excavation | Hard rock | 0.6 – 1 |
| Medium rock | 0.75 – 1.5 | |
| Tunnel excavation | Hard rock | 0.5 – 0.75 |
| Medium rock | 0.75 – 1.5 | |
| Concrete demolition | Mass concrete | 2 – 4 |
| Lightly reinforced | 1 – 2 | |
| Heavily reinforced | 0.75 – 1 |
Underwater work. Because there is no shock wave, the Cardox System can be activated while divers remain in the water and in close proximity to ships and structures — a job specification that conventional explosives simply cannot meet.
Send us the geology, the volume to be removed, and what is standing next to it. We will come back with a tube count, a method and a programme.
