Earthworks & Trench Excavation — Townsville & North QLD

Building trenches and footings excavated to engineer specification, with walls stripped back and the site handed over clean, compacted and ready for the next trade.

What the service involves

Once the concrete is cleared, the trench phase begins. We excavate building trenches to engineer-specified depth and dimensions, strip back the walls and prepare the ground for the next trade. It's the natural follow-on from our concrete demolition work — one crew, one accountable handover.

We capture before-and-after photography at every stage so you have a transparent record of the work, and the finished site is left clean, compacted and ready for construction.
