PRECISION BLASTING, LLCTrenching in Rocky Soils
Water, power, gas, fiber and septic lines — when the trench hits rock and stops.
Trenching is going fine right up until it is not. The bucket starts skipping, the trench stops going down, and now the whole utility schedule is stuck behind a rock nobody surveyed.
We drill and shoot the trench line so your excavator can come back through and clean it out to grade. You keep your crew and your machine; we just remove the reason they stopped.
Trench work we do
- Water and sewer mains
- Power, gas and fiber conduit
- Septic tanks, drain fields and leach lines
- Irrigation lines and stock water
- Foundation footings and frost walls
- Culverts and drainage lines
Working along a line
Trench blasting is a different problem from a bulk cut. The shot has to break a narrow corridor without over-breaking the trench walls or disturbing what is running alongside it — which is often a live utility. That means tighter hole spacing, lighter charges and more delays than a mass shot would use.
Call 811 before any excavation so buried lines get located. We will not shoot a trench line until that is done.

Questions about trench blasting
Can you blast a trench near an existing utility?
Often yes, with reduced charges and tighter delays. We need to know exactly what is running alongside it, which is why 811 locates come first.
Do I need my excavator on site?
Not for the shot itself. Most contractors shoot the line, then bring their machine back to clean out. We can coordinate either way.
How deep can you go?
Depth is rarely the limiting factor. Access for the drill and proximity to structures matter far more.
