Non Explosive Solutions

- When it comes to breaking rocks, using high explosives is the best bang for your buck, however sometimes this option is not on the table for one or more reasons, if this is the case, there are other options that we can provide..

Non explosive chemical cracking agent
This is a cement based product that when mixed with water and poured into a hole, it quickly hardens and expands with enormous pressure that cracks the rock. Advantages – no blast vibration or noise, no chance of flyrock, good cracking a rock along a strait line of holes. Disadvantages – may require the drilling of more holes than high explosive, often these holes may need to be at diagonal angles (more difficult). Slow, may take a few days in cold weather. Produces good cracking but no shattering and lifting like high explosives – bigger pieces and more difficult to dig out.

PCF, Nonex, Pyronex, Autostem and black powder
These products are listed on this page because some people try to present them as non explosive… don’t be fooled they certainly are explosives, but a different kind. They contain smokeless powders or a variation thereof. While they do not detonate like high explosives and shatter the rock with shock energy, they burn very rapidly and produce large volumes of expanding gasses that split the rock. Advantages – slightly less blast vibration and noise, good for producing large pieces of rock without lots of small shattered pieces.

Darda Hydraulic splitter
The Darda is a hydraulic cylinder powered three piece tappered wedge set that is inserted into a suitable hole drilled into the rock, the hydraulic cylinder pushes a wedge between two counter tapered “feathers” and forces the rock to split.
