THE CARDOX PRODUCT

What is CARDOX?

Originally developed for use in fiery coal seams, the CARDOX System is extensively used for breaking rock, concrete and many other materials expeditiously, with complete safety and without any adverse effects. CARDOX produces instantaneously a powerful heaving force, using carbon dioxide which cracks and breaks the material along natural and/or induced fracture plains whilst heaving it away from the mass of rock/concrete.

The CARDOX tube

HOW it works

One or more holes are drilled in the material to be broken and the CARDOX Tube(s) inserted. A connection is then made from the Tube(s) to a low tension activator, and on passing an impulse from this to the charged Tube(s), the low tension electric fuse initiates a rapid reaction in the energiser causing the liquid carbon dioxide in the Tube to change into gas, increasing its volume by 600 times in the process. The instantaneous build-up in pressure reaches the yielding pressure of the rupture (shear) disc which bursts releasing a heaving mass of CO2 which breaks the surrounding material. The whole process takes less than 1 second. By selecting the thickness of the rupture disc, the power of the Tube can be regulated to suit all conditions. After recovery the Tube, the heater and rupture disc are replaced, the liquid CO2 recharged and the Tube is ready to be used again.
