Exposed aggregate driveways and paving in Bairnsdale VIC

What exposed aggregate is

Exposed aggregate is concrete made with a decorative stone mix, where the top skin of cement paste is washed away after placing to reveal the stones. The result is a hard-wearing, textured surface that grips well, hides dirt and tyre marks, and looks natural beside brick, timber and render. It is the finish we are asked for most around Bairnsdale, Paynesville and Lakes Entrance.

Choosing your stone

Aggregate blends range from cool blue-grey and white mixes through to warm honey, rust and brown river pebbles. The colour of the cement can be tinted to sit underneath the stone. We bring sample boards to the site visit so you can see them against your house, roof and garden in daylight, because a stone that looks right in a brochure can look very different next to a red brick home or a grey Colorbond roof.

Timing the wash

Exposure is all about timing. Wash too early and stones come loose; too late and the paste has set too hard to remove evenly. On a hot Bairnsdale day with a northerly blowing, that window can be short, so we often use a surface retarder and plan the pour for the cooler part of the morning. Experience on the day is what makes the finish even from one end of the slab to the other.

Borders, bands and combinations

A smooth or honed border in charcoal or grey frames an aggregate driveway nicely and gives a clean edge against lawn and garden. Bands across the drive can line up with the house or hide joints. Some owners pair an aggregate driveway with a coloured or honed alfresco to tie the outdoor areas together.

Sealing and upkeep

Sealing brings out the colour of the stone and helps resist oil, tannin stains from gum leaves and the general grime of a busy driveway. We apply sealer once the concrete has cured enough and recommend resealing every few years, more often on driveways in full sun or near salt air at the lakes. Steep driveways and pool areas get an anti-slip additive.

Exposed aggregate beyond the driveway

The same finish works well for paths, side access, patios, pool surrounds and crossings within your boundary, so the whole property can share one look. A finer stone suits pool areas and spots where bare feet go, while a coarser blend gives drama on a long driveway. We often pour an aggregate driveway with a honed or coloured alfresco so inside and outside areas feel connected without everything being the same.

Why preparation still decides the result

Decorative stone only looks good for long if the slab underneath stays put. Every exposed aggregate job gets the same groundwork as any other driveway: soft clay or sand removed, a compacted crushed rock base, steel on chairs and properly spaced control joints. On reactive clay around Eastwood and Wy Yung we lean toward heavier steel and closer joints, because a crack running through a decorative surface is much more visible than one on plain concrete.

Living with exposed aggregate

Day to day, a sweep and an occasional hose keep it looking good. Oil drips should be cleaned quickly before they soak in, and gum leaves should not be left to sit through winter. A pressure clean and reseal every few years restores the colour. Avoid harsh acid cleaners, which can etch the stone and strip the sealer.

Bairnsdale ground, East Gippsland weather and Shire rules

Bairnsdale sits on terraces above the Mitchell River just before it runs out into Lake King. The older streets on the higher terraces mostly stand on red-brown loam over clay, which holds a slab well once the soft topsoil is gone. Down on the river flats toward Lucknow, the Macleod Morass and the Mitchell's lower reaches, the soil turns to fine grey alluvial clay that stays wet after rain and has gone under in big floods. The rising country at Wy Yung, Eastwood and Granite Rock has duplex soils where a thin sandy top hides stiff, reactive clay, and the lakes towns of Paynesville, Eagle Point and Metung bring sand and a high water table. Summers are warm and dry with the odd scorching northerly, winter mornings can frost, and east coast lows can drop a month of rain in two days. A test hole goes in at every site visit, and we set the excavation, base, steel and curing to suit what comes out of it.

Inside your own fence line, a driveway, path or patio rarely needs a permit. Once the work leaves your title and runs over the verge, footpath or kerb, it requires consent from East Gippsland Shire Council, which looks after Bairnsdale, Paynesville, Lakes Entrance, Metung, Bruthen, Orbost and the surrounding districts. Access onto the Princes Highway or the Great Alpine Road is a state road and involves the Department of Transport and Planning as well. Flood overlays, bushfire attack level ratings, house slabs and larger sheds can bring a building surveyor and engineer into the job. Your quote spells out which of those applies.

What a Bairnsdale Concreting quote shows you

Our quotes are written up after we have stood on the site, and they break the work into the pieces you would want to question. You will see the area we measured, any demolition of old slabs, pavers, bitumen or gravel and where it will be tipped, how deep we plan to dig, the crushed rock we will bring in and how many compacted layers it goes down in, the concrete strength, how thick the slab will be, and the reinforcement plus the chairs that lift it, the surface finish or stone mix, the joint layout, pits and stormwater connections, edges, steps and sealer. A vehicle crossing permit from East Gippsland Shire, a concrete pump, a long wheelbarrow run behind a house, or protection for a neighbour's garden are each listed as their own line.

We do not publish rates per square metre. Around Bairnsdale a driveway can sit on free-draining red loam on the river terraces, on grey alluvial clay down on the Mitchell River flats, on heavy duplex clay up at Wy Yung, or on loose lake-edge sand at Paynesville, and those four sites need four different bases. A figure printed on a website would be wrong for most of them, so we look first and quote what your block actually needs.
