Concrete cleaning and sealing in Bairnsdale VIC

Why sealing matters

Sealer protects concrete from stains, UV, water and wear, and on decorative finishes it brings out colour and depth. Without it, exposed aggregate turns dull, coloured concrete fades and oil spots soak in. Gum trees drop leaves that leave tannin stains on unsealed concrete, which are common around Bairnsdale.

Cleaning first

A sealer is only as good as the surface beneath it. We pressure clean, treat oil and rust marks, remove mould and old flaking sealer, and let the slab dry before sealing.

Choosing a sealer

Solvent-based acrylics give a wet-look sheen on aggregate and stamped work. Water-based sealers give a more natural look. Penetrating sealers protect without changing appearance. Pool areas, ramps and steep driveways get an anti-slip additive. We recommend the right product for your surface and how it is used.

How often to reseal

Most decorative driveways in East Gippsland need resealing every two to four years, more often in full sun or salt air near the lakes. Covered alfresco areas last longer.

New concrete

New slabs need to cure before sealing. We schedule sealing for new jobs at the right time and include it in the quote when you want it.

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.
