Colby Services

We offer a rock breaking/blasting service where we will go to a site or house, building site, construction site etc. We explain how we go about the rock breaking. We will then send you a quote with all the details you need to know on the methods ... 

NoneX Blasting cartridges 

NoneX™ technology is based on a non-detonating chemical compound enclosed in a cartridge, which reacts very quickly when ignited to produce high volumes of gas, mainly consisting of nitrogen, carbon dioxide and steam.

When the cartridge is confined in a drill hole, the gas generated by the ignition of the propellant enters into the micro-fractures created from the percussive drilling process and into the natural fractures and planes of weakness of the rock to produce a shearing of the rock or concrete often called splitting.

 Advantages compared with traditional explosives:

Soundless, non-explosive material

  • Safe, without any flying stone, ash, no toxic gas and shock wave
  • Low cost and effective: suit for precious stone and explosion-not allowed area
  • Shape is controllable: can get available size according to our operation ways
  • Without any special importing license: can import as general cargo
  • Can be used in an almost unlimited range of applications
  • Particularly used for breaking, cutting or demolishing stones, concrete and reinforced concrete
  • Ideal for use in situations where surrounding buildings or other structures would be damaged by flying debris or vibration.
