Vision

We’re changing the way the world thinks about blasting and explosives

With the advent of non-detonating blasting technology, the world is quickly adopting a new and safer way to blast rock and concrete without the otherwise unavailable consequences of shock and throw rock.


Why AutoStem?

An improved approach to blasting, demolition and general quarrying and mining. AutoStem Blasting Cartridges enable the possibility of focused, local blasting without the requirement for large clearing areas, discontinuous mining cycles and traditional safety concern.

Industry Regulators


AutoStem Cartridges are accredited with international standard's bodies world-over, we are in fact the only blasting cartridge provider who's product lines can be exported to every continent.

Our services

  • Self-Stemming Blasting Cartridge

    With an emphasis on safety, AutoStem rock breaking cartridges do not require any tamping or stemming action.

    Upon initiation, the cartridge functioning includes a stemming action which closes the borehole for the blaster.

  • Safety Switch Technology 

    All AutoStem blasting cartridges are fitted with a patented safety switch, preventing any possible initiation prior to "unlocking" the product for use in the borehole. 

    The AutoStem Blasting Cartridge does not require the use of a detonator, meaning explosive accessories are not a requirement when blasting.
