Comparing concrete quotes in Ferntree Gully

Look beyond the total

A bottom-line number does not show what is included. One quote may cover removing the old driveway, deeper excavation, a thicker base, extra steel, drains and a pump; another may leave them out and charge later. Ask for itemised quotes.

Removal and digging

Is the existing surface being removed and taken away? How deep will excavation go? What happens if soft clay, roots or old fill are found?

Base, thickness and reinforcement

What type and depth of crushed rock, and how is it compacted? How thick is the slab, and what reinforcing is used? Is it designed for the heaviest vehicle, such as a caravan, boat or work van?

Joints and water

Where will joints be placed? Are pits, grated drains and pipes included, and where do they discharge? On sloping sites, are cut-off drains included?

Finish and sealing

Which finish or blend is included? Is sealing included, and does it include anti-slip additive?

Pump, access and protection

Is a concrete pump included if needed? What protection is allowed for neighbours' driveways, footpaths and gardens?

Council and engineering

Does the quote include the crossover application and footpath reinstatement? For slabs and walls, who provides engineering and building permits? Knox City Council covers most of the area; Yarra Ranges covers Upwey and parts of the hills.

The concreter

Did they visit and dig a test hole before quoting? Who will do the work? Are they insured? A quote based on a careful site visit is far more likely to hold.
