When You Need Us
When You Need Trenching Services in Auckland in Auckland
New Water Supply Connection Needed
Your new build needs a water connection from the Watercare main to the house. We dig the trench to the required 600-900mm depth, prepare the bedding, and backfill once the pipe is laid — ready for the plumber to make final connections.
Sewer Line Replacement on an Older Property
Your existing sewer line has collapsed or is blocked beyond repair. We excavate the trench along the pipe route, remove the old line, and prepare the trench for the licensed drainlayer to install the replacement at the correct grade.
Underground Power or Fibre to a Rural Property
Your rural section needs power cables or fibre run underground from the road boundary. We cut the trench to the network operator's specified depth and width, lay warning tape, and backfill with approved material.
Subdivision Services Installation
A multi-lot subdivision requires trenching for water, wastewater, stormwater, power, and fibre across the entire development. We coordinate the trenching programme so each service goes in at the right sequence and depth.
Stormwater Drainage Trench for a New Development
Your site needs stormwater pipes installed at a specific grade to connect into the council network. We dig the trench to the engineered fall, prepare the bedding layer, and backfill around the pipe to prevent movement.
Trenching Through Rock
Your trench route hits volcanic basalt or solid rock that a standard bucket cannot cut through. We switch to hydraulic breaker attachments or rock saws to get through hard ground without blasting.
Deep Trench for Sewer Main
A deep sewer trench — over 1.5 metres — requires shoring or benching to keep workers safe. We install trench shields or bench the sides back to a safe angle before any pipe installation work begins in the trench.
Service Trench Across a Driveway or Road
Underground services need to cross an existing driveway, private road, or accessway. We cut the trench, install the service, backfill with compacted material to prevent settlement, and reinstate the surface to match what was there before.
Our Process
Our Trenching Services in Auckland Process
Blake Civil Construction follows a systematic approach for every trenching services in auckland project.
Beforeudig Enquiry and Service Location
We submit a Beforeudig request to identify all existing underground services along the trench route. Existing pipes, cables, and ducts are located and marked before any digging starts.
Trench Route Planning and Set-Out
Working from the engineer's drawings, we mark out the trench route on site — confirming depth, width, grade, and any points where the trench crosses existing services or structures.
Excavation to Specified Depth and Grade
Our excavators cut the trench to the required dimensions — maintaining consistent depth and fall along the full length. Spoil is stockpiled alongside the trench or loaded for removal.
Bedding Preparation
The trench floor is levelled and a bedding layer of sand or approved granular material is placed at the correct thickness to support the pipe or cable evenly along the trench.
Backfill and Compaction
Once the service is installed, we backfill the trench in layers using approved material. Each layer is compacted to prevent future settlement — especially under driveways, roads, and paved surfaces.
Surface Reinstatement
The surface is reinstated to match existing conditions — whether that is topsoil and grass, compacted gravel, base course, or asphalt. Reinstatement meets council standards for any work done in road reserve or public land.

Why Choose Us
Why Choose Blake Civil for Trenching Services in Auckland?
Full Range of Excavators
Our fleet runs from 1.5-tonne mini excavators for tight residential sites through to 14-tonne machines for deep or long trench runs. We match the machine to your site so trenches get dug without damaging surrounding ground.
Rock Trenching Capability
When a trench hits rock, we do not stop. Hydraulic breaker attachments on our excavators cut through Auckland's volcanic basalt and sandstone so the trench reaches the required depth regardless of ground conditions.
Beforeudig and Service Location
Every trenching job starts with a Beforeudig enquiry and physical service location. We identify what is already in the ground before we dig — avoiding costly damage to existing water, gas, power, and fibre services.
Depth and Grade Accuracy
Our operators use laser levels and grade control to maintain accurate trench depth and fall over the full length. This is critical for gravity-fed sewer and stormwater lines that depend on consistent grade to function.
Safety-First Trench Management
Deep trenches are shored or benched in accordance with WorkSafe requirements. Our crew holds current site-safe certifications and follows documented safe work procedures for every trench over 1.5 metres deep.
Reinstatement to Council Standards
We reinstate trenches to the standard required by Auckland Transport and local council — whether in road reserve, footpath, berm, or private property. No loose ends or unfinished surfaces left behind.
