Canberra Trenching
Trenching in Canberra for sewer, water, stormwater, power and NBN. Existing services located first, then dug to depth, bedded and backfilled right.
Trenching Canberra
Trenching in Canberra provides clean, accurate channels for water, drainage, gas, power and communications. A well-dug trench to the right depth, width and fall makes installation easier and helps your services work reliably and pass inspection. Accurate trenching saves time, prevents damage and helps your installation pass inspection first time. Tell us your route, depth and what is going in the trench, and we will mark the line and check existing services. Canberra's clay, rock and frosty ground can slow trenching, so experienced operators in Belconnen, Gungahlin and Woden work carefully, backfill neatly and leave properties tidy. Expect tidy results.
- Services located first — Existing pipes and cables found before we dig a trench alongside them
- Dug to cover depth — Each service has its own cover depth, and power, water, sewer and comms all differ
- Bedded correctly — Pipes and conduit sit on and in clean sand, never dropped onto rubble
- Compacted backfill — Filled and compacted in layers so you don't end up with a sunken strip
- Marker tape & conduit — Warning tape and conduit put in wherever that service needs them

Canberra Trenching Services
Service and drainage trenches dug right the first time, so nobody's digging them up again.
Sewer and water lines
We trench to the correct grade for your sewer and water pipes, then bed and backfill each one to the standard it needs.
Underground power
Trenches for power cables and conduit dug to the right cover depth, with bright warning tape laid on top for whoever digs next.
NBN and data runs
Getting NBN or data cabling underground? We'll dig the conduit trench and line up timing with your installer so the cable goes straight in.
Stormwater drains
Drain lines laid to a steady fall, plus pits big enough for the roof and paved areas draining into them, ready for those big summer downpours.
Garden irrigation lines
Shallow trenches for your garden watering system, dug just deep enough that the mower and edger never find the pipes.
Fixing old trenches
Got an old trench line that keeps sinking? We'll backfill it, compact it properly and reinstate the surface so it disappears for good.
Canberra Trenching Process
Before anything else we find out what's already buried; after that, it comes down to depth, bedding and backfill. We'll have existing services located and route the trench around them, since a machine hitting a live cable is a genuine safety incident, not just a hassle. The depth and grade depend on what's going in: sewer and stormwater need an even fall, while power and comms need the right amount of cover. We dig to that grade, bed the trench, lay and check the service before it's covered, then backfill in compacted layers and reinstate the surface so you won't see a sunken line come winter.
Service Location & Route Planning
We find what's already buried and route the trench around it, hand digging wherever a location needs confirming.
Excavate to Depth & Grade
The trench goes down to the cover depth your service needs, with a steady fall for any gravity drainage line.
Bedding & Service Laid
Sand bedding goes down, then we or your tradie lay the pipe or conduit, with warning tape over it where needed.
Backfill, Compact & Reinstate
We backfill and compact in layers, then restore the surface so the trench doesn't sink into a dip later on.
Why Choose Our Trenching Experts in Canberra
Trenching usually goes wrong in one of two ways: a buried service gets hit, or the backfill sinks. Both can be prevented.
Services located, then hand-proven
We locate services, then hand dig to confirm them where it counts. Digging blind with a machine next to a live line is how injuries happen.
Cover depths respected
Every service has its own minimum cover, so we dig to what yours requires, not one depth for everything.
Bedded properly
Clean sand under and around every pipe, so nothing rests on rock and cracks once the load comes on.
Backfill compacted in layers
Most trenches sink into a visible dip because the backfill went in all at once. We compact ours in layers.
Coordinated with your trades
We time the dig so your plumber, electrician or NBN installer walks onto an open trench, not a wait.
Fixed-price quotes

Trenching questions we get asked in Canberra
Quick answers to what Canberra homeowners usually ask us before getting a price.
How do you keep clear of buried services?
We have them located and plan the trench route around them before any digging. A machine hitting a live cable is a serious safety incident, not a minor hassle, so we never skip this.
What depth does a trench need?
That depends on what's going in. Sewer and stormwater need a steady fall, while power and comms need a minimum cover. We dig to the requirement for your service, not a rough rule.
Why does bedding matter?
It holds the pipe or conduit evenly so it's not sitting on rocks or clumps of spoil. Without good bedding, sewer lines sag and conduit can crack under load.
How is the trench backfilled?
In compacted layers, with the surface put back so you can't still see the line next winter. Spoil just shovelled back in will sink into a trench-shaped dip.
Can you dig a trench near a house or fence?
In most cases, yes, though really tight spots may need part of it dug by hand. We pick that up when quoting, since it affects both time and cost.
