Tunnelling, Trenching and Shaftsinking

Before:

After:

Greece - Athens Metro System.
Four CARDOX Tubes breakout centre section of tunnel.

South Africa - Excavation of shaft adjacent to main road under gas, electricity and water mains

Underwater Excavation

Before:
CARDOX Tube about to be activated.

During:
Diver can stay in water, no shockwave, no noise.

After:
No danger to marine life. Used in close proximity to ships/structures.

Harbour Deepening and Widening
Excavations of Seabed for Cable/Pipeline installations
Breaking Concrete Overspills
Deepening of Riverbeds

CADOX, a fast, efficient and safe way to break rock.

Concrete Demolition

The Keban Dam, Eastern Turkey
Breaking out of 4 channels each 6.5m wide across spillways of dam.

Before
CARDOX Tubes placed in drill holes.

After
Engineers view the results. The reinforced concrete is completely broken.

Busy stretch along River Thames, London. Excavation of reinforced concrete dolphin adjacent to exclusive new apartment block and half a mile from the tower of London in one direction and Canary Wharf seen in the background.

CARDOX Tubes are placed and wired - up.
CARDOX Tubes break the reinforced concrete.

Yields in various applications

Applications	Excavations/Strata Type	Average yield per CARDOX Tube in cubic metres
Quarrying	General Dimensional Stone	3 to 6 5 to 20
General Open Cut Excavations	Hard / Medium Rock	3 to 5
Foundation Excavations	Hard Rock Medium Rock	0.75 to 1 1 to 1.5
Trench Excavations	Hard Rock Medium Rock	0.6 to 1 0.75 to 1.5
Tunnel Excavations	Hard Rock Medium Rock	0.5 to 0.75 0.75 to 1.5
Concrete Excavations	Mass Concrete Lightly Reinforced Concrete Heavily Reinforced Concrete	2 to 4 1 to 2 0.75 to 1

CARDOX, controlled concrete demolition for sensitive areas.

Two CARDOX Tubes split and heave a block of over 50 tonne.

CARDOX Tubes applied horizontally to lift a block along its natural bed plane.

When using CARDOX, very little wastage results, as the gas splits and heaves along natural fissures and bed planes.

What the Quarry Managers say...

"Fewer drill holes reqired than when using black powder."

"Lower cost than using black powder."

"Easier to use than other methods."

"Lower noise emission than explosives."

“Horizontal and vertical applications."

"Less waste."

"Virtually no dust."

"No magazine required."

"No stemming operation needed."

"Longer shelf life than other methods."

All the benefits of explosives.. with none of the headaches.
