Rock Cracker

The Rock Cracker is a non-explosive rock-splitting tool that makes use of the technology of motive force. A device filled with a motive medium cartridge generates a pressure impulse in the device. The pressure impulse is transmitted by means of a path into an incompressible fluid column (water of gel) situated in a pre-drilled hole in the rock..

The success of the system is due to the special technology of the motive force being used. The unique qualities of the motive force and the cartridge generate a rapidly advancing force wave.

This impulse pressure starts the spread of the fracture surfaces in the direction on the stress concentrations and the next free surface. The static pressure developed by the motive medium generates a further mechanical pressure in the rock where by the rock bursts. The direction of the break can be controlled by the arrangement of the drilling or the indentation of the hole.

The Rock Cracker is a non-explosive rock-splitting tool that makes use of the technology of motive force. This block is approximately 3m³.
