Directional boring & underground
Services run under driveways, roads and established gardens — without trenching straight across them.
Trenching is the cheapest way to get a service from A to B right up until it crosses something you care about. A driveway, a road, a mature garden bed, a paved area — reinstating any of those costs more than the boring would have.
Directional boring puts a bore under the obstacle and pulls the conduit through behind it. What's on the surface stays exactly as it was.
What's included
- Horizontal directional boring under driveways and roads
- Conduit and service crossings
- Water, power, comms and irrigation runs
- Conventional trenching where it's the cheaper option
- Bore entry and exit pit excavation
- Backfill and reinstatement
- Service location before work starts
Why it matters
Reinstatement is the hidden cost of trenching.
The comparison people make is boring versus trenching per metre, and on that number trenching usually wins. It's the wrong comparison.
The real number is trenching plus saw-cutting, plus removal, plus new concrete or asphalt, plus the wait while it cures, plus whatever the mature garden was worth. Against that, a bore under the obstacle is frequently the cheaper option and always the faster one.
We'll look at both where both are viable and let you see the difference, rather than pushing you toward whichever suits our machine.
Questions
Common questions
Depth and distance depend on ground conditions and what's already underground. We'll assess on site — sandy Peninsula ground behaves very differently to clay or rock.
Always. Service location happens before any bore or excavation starts. Hitting an unmarked service is dangerous and expensive, and it's avoidable.
Per metre, usually. All up, often not — once you add reinstating the driveway, road or garden the trench went through. We'll price both where it makes sense.
Technically yes, though works within a road reserve need approval from the road authority or council. We'll tell you what applies to your crossing.
