Exposed Aggregate Driveways in Sale: Stone Choices, Costs and Care

Exposed aggregate has overtaken plain concrete on most Sale driveway quotes we send out in 2026. The look is sharper, the grip is better, and the price has come back to a range where it competes with a decent plain finish. The catch is that two exposed aggregate driveways quoted at the same per-square-metre rate can land looking completely different. The stone matters. The seal matters more. Here is what we tell people in Sale at the site visit.

What exposed aggregate actually is

Exposed aggregate is plain concrete with the top layer of cement paste washed off so the stone in the mix becomes the surface. The mix is poured the same way as a normal slab. While it is still green, we apply a surface retarder, wait the right amount of time, and then wash and scrub the top millimetre or two back to expose the stone underneath. The slab strength, the mesh, the base prep and the joints are identical to a plain driveway. The finish is what changes.

Because the stone is the finish, the look is decided at the mix design, not the trowel. Pick the wrong stone and no amount of finishing will save it. Pick the right one and a half-decent pour looks great.

What it costs in Sale (2026)

Standard residential exposed aggregate driveways in Sale in 2026 sit in the following ranges, supplied and laid:

Per-square-metre rates above are the slab and finish only. On top of that, expect line items for tear-out (typically $40 to $80 per m² if you are replacing an existing driveway), the council crossover if it needs doing ($1,500 to $4,500 in Sale through Wellington Shire), pump-truck hire for any pour with poor access ($1,200 to $1,600 minimum), and the seal coats (covered below).

Stone choices and what they look like

The single biggest decision on an exposed aggregate driveway is the stone. We always pour a sample board, around 600mm by 600mm, in two or three mixes before the main pour so you can see the actual finish on your block in your light. Photos online lie. The same stone looks darker in Paynesville sea light than it does on a hot Stratford afternoon.

Local river pebble blends

Locally batched mixes around Sale typically pull from Gippsland river-stone sources. The result is a warm grey-brown finish with a fair bit of natural variation. Good for older Sale weatherboards and brick veneer homes that already have warm tones in the cladding. Forgiving on the eye when there are leaves and dust on it.

Sharp grey blends

A bluestone-heavy mix gives a cooler, more uniform grey that suits newer Sale estate homes and rendered facades. The contrast against a black garage door or a charcoal fence is the look most builders are spec-ing right now. Hides oil drips better than warm blends.

Premium imported stones

Granite, quartz and crushed marble blends sit at the top of the range. Strong, consistent colours including white, gold, deep black and salt-and-pepper looks. Worth considering on showpiece driveways where the design is doing visual work. Lead times are longer because the stone comes from interstate or overseas.

Coloured oxide bases

An oxide added to the mix tints the cement matrix so the visible concrete between the stones is not grey. A charcoal oxide under a sharp grey blend reads almost black. A buff oxide under a warm pebble mix reads sandstone. Subtle but it lifts the finish from 'driveway' to 'design piece'.

The seal coats: the bit most people skip

An unsealed exposed aggregate driveway in Sale lasts. It just does not stay sharp. Within twelve months you get oil drips that soak in, leaf tannins that stain, salt blooming on driveways near the Lakes, and a flat dusty grey where the cement matrix used to read crisp. The seal is what keeps the colour and stops the stone going chalky around the edges.

We spec two coats of a quality penetrating seal on every exposed aggregate driveway. The first coat goes on around 28 days after the pour, once the slab has cured properly. The second coat goes on a fortnight after the first. From there, plan on a re-seal every two to three years to keep the finish singing. Re-seals are quick and cheap, usually a half-day on site.

How the pour actually works

An exposed aggregate pour is more time-sensitive than a plain pour. The window between 'too early' and 'too late' to wash off the retarder is roughly an hour, and it shifts depending on temperature, sun and wind. We watch the slab through the whole pour and call the wash when it is right, not on a clock.

1. Excavation, compacted crushed-rock base, formwork and SL82 mesh, same as a plain driveway
2. Concrete is delivered to a 25 MPa spec or stronger, with the chosen stone in the mix
3. Slab is screeded, bull-floated and finished, then a surface retarder is applied while still wet
4. Slab is left to cure to a controlled window. Usually 4 to 8 hours depending on conditions
5. Top layer is washed back with a fine spray and a stiff brush until the stone reads at the right depth
6. Control joints are cut in within 24 hours
7. First seal coat at 28 days, second seal coat at 42 days

Town-by-town: what we watch for in Gippsland

Sale (Wellington Shire)

Sale soils are forgiving and most blocks are flat with kerbside access, which keeps the pour simple. Wellington Shire crossovers run through a permit team that knows our work. Sharp grey blends are pulling well in the newer estates around Sale East and Wurruk. Warm pebble blends still suit the older heritage streets in the town centre.

Traralgon and the Latrobe Valley

Reactive clay through the Valley means edge beams sit deeper and we run a slightly stronger mix on the slab itself. The seal coat matters more here than anywhere else in Gippsland because the freeze-thaw cycle in July and August is real. A driveway sealed properly gets through ten winters without surface dust. An unsealed one starts looking tired by year four.

Bairnsdale and East Gippsland

Growth-corridor blocks out toward Lucknow and the airport often need a heavier base. East Gippsland Shire uses a slightly different crossover drawing to Wellington Shire and we set out accordingly. Local stone tends to read a touch warmer than the Sale equivalent because of the soil colour reflecting up.

Paynesville and the Lakes

Salt air is the variable. Salt does not damage a sealed exposed aggregate driveway but it will dull an unsealed one fast, and the white blooming that comes through is hard to clean once it is set in. We spec two coats of a penetrating seal as standard on every Paynesville job and recommend a re-seal at 18 months instead of 24 to 36 months elsewhere.

Stratford and the Avon flats

Long rural driveways and lifestyle-block entries. We usually go 125mm on the slab instead of the standard 100mm because of ute, trailer and caravan loads. Sample board placement matters more on rural blocks because there is more open sky and the finish reads differently than it does in a Sale streetscape.

What pushes the price up

• Premium imported stones (granite, quartz, white marble blends)
• Coloured oxide bases under the mix
• Curves and feature shapes in the set-out
• Strip-banded designs where two stone choices meet a saw-cut line
• Tear-out and disposal of an existing driveway
• Pump-truck access for backyard or restricted pours
• Council crossover if it needs replacing or upgrading
• Larger area, smaller savings per m² because mobilisation is a fixed cost

What pushes the price down

• Standard local river pebble mix instead of an imported stone
• Simple rectangular set-out with no curves
• Existing crossover in good condition that stays in place
• Single-day pour with kerbside access
• Combining the driveway with a path, shed slab or patio so we are on site for one mobilisation

How long it takes

A typical residential exposed aggregate driveway in Sale takes us between four and six days on site. One day for excavation and base prep, one for formwork and mesh, one for the pour and the wash-off, and a day or two of curing before you can walk on it. Vehicles stay off for at least seven days. Seal coats happen later, on separate visits, so you have full use of the driveway in the meantime.

Plain vs exposed vs decorative vs spray pave

If you are weighing exposed against the alternatives, the quick read is:

• Plain non-slip finish: cheapest, simplest, no design statement. Right call when the budget is tight or the driveway is hidden
• Exposed aggregate: sharp look, good grip, hides drips, broad price range. Most common choice in Sale right now
• Decorative (stamped, stencil, coloured): more design control, more upkeep. Better for paths and patios than driveways in our experience
• Spray pave over existing concrete: cheaper than tearing out, but only works if the existing slab is sound. Covered separately on the blog

Care and maintenance

Once it is sealed, an exposed aggregate driveway wants almost nothing from you. Sweep it. Hose it occasionally. Lift oil drips with a mild degreaser as soon as you see them, not three weeks later. Avoid pressure-washing on full bore because aggressive water can lift the seal at the edges. Re-seal every two to three years (every 18 months near the coast) and the finish stays sharp for the life of the slab.

Common mistakes to avoid

• Skipping the sample board. The mix on the truck has variation, but the sample board is the closest you get to the real finish before you commit
• Skipping the seal coats. Saves a few hundred dollars on day one, costs you a tired-looking driveway by year three
• Trying to match an existing pour. Exposed aggregate has natural variation from batch to batch. A new section next to an old one will always read different
• Picking the stone from a brochure. Light is different on every block. We bring the sample board to you
• Pouring over a marginal base. The finish does not save a slab that was not prepped right. The cracks come through eventually
