Mandurah Trenching
Trenching in Mandurah for sewer, water, power, comms and stormwater. Dug to depth with correct bedding and backfill, services located first.
Trenching Mandurah
Trenching sounds like the simplest kind of digging and carries the highest risk, because a trench is usually being dug precisely where other services already run. It also has requirements most people do not expect: minimum cover depths that vary by service type, bedding sand under and around a pipe, and backfill compacted in layers so the trench line does not sink into a visible scar across your lawn a year later. Our trenching Mandurah work starts with locating what is already in the ground, and we dig to the cover depth and bedding the service actually requires.
- Services located first — What is already in the ground identified before we open a trench beside it
- Dug to cover depth — Minimum cover varies by service — power, water, sewer and comms are not the same
- Bedded correctly — Sand bedding under and around the pipe or conduit, not backfilled onto rubble
- Compacted backfill — Layered and compacted so the trench line does not sink into a visible scar
- Marker tape & conduit — Warning tape and conduit laid where the service type calls for it

Irrigation & retic trenches
Shallow trenching for reticulation, dug to keep lines below mower and edger depth.
Trench backfill & reinstatement
Existing trenches backfilled, compacted and the surface reinstated so the line stops showing.
Mandurah Trenching Process
Locating what is already there comes first. Everything after that is depth, bedding and backfill. We have the existing services located and plan the route around them, because a trencher meeting a live cable is a serious incident rather than an inconvenience. Depth and grade come from whatever is going in — stormwater and sewer need a consistent fall, power and comms need their cover depth. The trench is dug to that grade, bedded, and the service laid and checked before anything covers it. Backfill goes in compacted layers, and the surface is reinstated so the line is not still showing next winter.
Service Location & Route Planning
We identify existing services and plan the trench route around them, hand digging where we need to prove a location.
Excavate to Depth & Grade
Trench dug to the cover depth the service requires, and to fall where the line is gravity drainage.
Bedding & Service Laid
Sand bedding placed, the pipe or conduit laid by us or your trade, then marker tape over where required.
Backfill, Compact & Reinstate
Backfilled in layers and compacted, then the surface reinstated so the trench line does not settle into a trough.
Why Choose Our Trenching Experts in Mandurah
Two things go wrong in trenching: striking an existing service, and backfill that settles. Both are avoidable.
Services located, then hand-proven
We locate first and hand dig to confirm where it matters. Machine-digging blind beside a live service is how people get hurt.
Cover depths respected
Each service type has its own minimum cover. We dig to the requirement rather than a single default depth.
Bedded properly
Sand bedding under and around, so a pipe is not resting on rubble waiting to crack under load.
Backfill compacted in layers
The reason most trench lines show as a sunken stripe a year later is backfill tipped in one go. We layer it.
Coordinated with your trades
Timed so your plumber, sparky or comms installer can lay in an open trench rather than waiting on us.
