Typical size
Driveways 30 to 80 m², paths and patios 10 to 40 m²

Much of Newcastle’s housing was built when a driveway was two strips or a thin slab meant for one small car. Decades of heavier vehicles, tree roots and clay that swells and shrinks have done the rest. When a slab has cracked through, dropped at the joints or lifted at the edges, patching buys a season. Replacement fixes it.

What removal involves

The old concrete is cut at the limits of the job, broken out with an excavator or a breaker, loaded and carted to a recycling yard. Saw cuts at the boundary and against anything being kept, such as a garage slab or a neighbour’s driveway, give a clean edge to pour against. Services are located first. Both councils leave the Before You Dig enquiry with the owner or the contractor, and it matters most on old streets where pipes are shallow and unrecorded.

Fix the cause, not only the surface

Removing the slab is the chance to see why it failed. Soft spots are dug out and the base rebuilt where the ground calls for it. Roots are dealt with, by an arborist where a tree is protected. Levels are reset so water runs to the street or a drain instead of the garage. Then the new slab is poured to the specification, with mesh inside the concrete and joints where they belong.

The crossing comes out too

If the council crossing is part of the failure, it is replaced under the same approval a new one needs, and an old layback that is no longer used has to be removed and the kerb reinstated. The Section 138 guide explains how each council handles it.

Choosing what goes back

Replacement is the moment to get the driveway you would have chosen: wider, in exposed aggregate or coloured concrete, with a path to the door poured at the same time. See concrete driveways for the three finishes.

Removal adds about $35 per m² to the new concrete. The cost guide and the calculator include it as a tick box. When you are ready, request a measure.

Asked and answered

Concrete removal and replacement: common questions

How much does it cost to remove an old concrete driveway?

Removal adds about $35 per square metre to the price of the new concrete. That covers breaking out, loading and tipping. Thick or heavily reinforced slabs, poor machine access and tip distance can lift it. On a 40 square metre driveway, removal is about $1,400 on top of the new pour.

Can new concrete be poured over the old driveway?

It is rarely worth it. A thin topping copies every crack beneath it, raises levels at the garage and the footpath, and fails early. Where the old slab has cracked or sunk, the cause is usually in the base, and the only way to fix the base is to take the slab out.

Do I need council approval to replace my crossing?

Yes. Both City of Newcastle and Lake Macquarie City Council treat a replacement crossing like a new one, with an application under Section 138 of the Roads Act. Lake Macquarie states that a replacement needs a fresh application and fee. Replacing concrete inside your boundary does not usually need road approval.

Why did my old driveway crack?

The usual causes here are reactive clay moving beneath a slab with too little base, tree roots lifting one side, thin concrete with the mesh sitting on the ground instead of inside the slab, and too few joints. The replacement is planned around whichever of those applies.
