Deep basement excavation retained by sheet-pile walls

Excavation

Bulk and detailed excavation for basements, footings and services, with spoil classified and removed.

Get a quote

Once the building is gone, the ground is next. Because the same crew did the demolition, there is no gap between the last truck of rubble and the first bucket of dirt. We dig to the engineer's levels, break the rock Sydney is known for, and classify every load of spoil before it leaves site.

What's included

Excavator with a hydraulic rock breaker working through sandstone

Dug to level. Rock broken. Spoil classified.

How we run it

Every excavation job follows the same order, so nothing is missed and the next trade gets a site they can start on.

  1. 01

    Review the design

    Check the excavation plans, geotechnical report and shoring design, and confirm levels.

  2. 02

    Locate services

    Underground services located before digging and dilapidation records taken where required.

  3. 03

    Dig

    Bulk excavation in stages that suit the shoring, then detailed excavation to level.

  4. 04

    Classify and remove

    Spoil classified and trucked to licensed facilities with dockets for every load.

  5. 05

    Hand over

    Excavation trimmed to level and handed to the builder or the next trade.

Common questions

Can you do the demolition and the excavation?

Yes. One contract covers both, so there is no hand-over between contractors.

Do you break rock?

Yes. Sandstone and shale are common in Sydney basements and rock breaking is part of the excavation scope.

Where does the spoil go?

It is classified first, then taken to a facility licensed to accept that class of material.
