Concrete Demolition & Saw Cutting — North Queensland

Precision diamond-blade saw cutting and reinforced concrete slab removal for commercial and industrial sites across Townsville, Mackay and Cairns.

What the service involves

Concrete demolition in North Queensland usually means thick reinforced slabs over compacted fill, often with live services running underneath. We start every job with a full site assessment and service location — mapping every underground utility and setting up exclusion zones before the first cut is made.

Our saw cutting team uses diamond-blade flat saws to score precise lines across the slab, giving clean, controlled cuts that prevent cracking beyond the designated removal zone. Once sections are isolated, our jackhammer crews break the concrete into manageable rubble.

The broken concrete is then loaded out and removed from site the same day where possible, leaving a clean, compacted base ready for the next trade. Before-and-after photos are captured at every stage so you have a transparent record of the work.

Frequently asked questions

How long does concrete demolition take?

It depends on slab thickness, reinforcement and access, but most commercial slab jobs are scoped in days, not weeks. We give you a clear timeline with your quote.

Do you remove the rubble?

Yes. Broken concrete is loaded out and removed from site — usually the same day — so you're left with a clean, compacted base.

Can you cut around live services?

Yes. We locate and map all underground services first, set exclusion zones, and cut to protect anything that needs to stay live.

Do I need a council permit for slab removal?

Some work requires approvals depending on the site and scope. We'll flag what's needed during the quote so there are no surprises.
