Coloured concrete in Ferntree Gully

Colour that suits the street

Ferntree Gully's streets are a mix of 1970s and 1980s brick veneer, weatherboard cottages near the station, and modern rebuilds in render and dark cladding. Coloured concrete lets a driveway and paths complement the house instead of sitting as a grey afterthought.

Through-colour and colour hardener

With through-colour, oxide pigment is mixed into the whole batch, so chips and wear show the same colour. With colour hardener, a blend of pigment, cement and hard fine aggregate is worked into the fresh surface, giving stronger colour and a tougher top layer. We recommend the method based on the area's use and the look you want.

Choosing a colour

Start with what cannot change: brick, roof, cladding and trims. – cream and tan brick pairs well with sandstone, buff and light brown – red and orange brick suits terracotta, warm brown and mid grey – dark roofs and modern facades suit charcoal, slate and graphite – mid greys hide dirt and leaf stains best on tree-lined streets Very dark colours get hot in full sun, so we may suggest a lighter tone around pools.

Finishes with colour

Broom-finished colour for driveways and paths, smooth or honed colour for covered patios, and colour combined with stamped or stencil patterns. Colour also works well as a border around exposed aggregate.

Efflorescence and variation

White bloom called efflorescence can appear as moisture carries salts to the surface. It usually fades and can be cleaned before sealing. Colour can also vary slightly between truckloads, so we plan pour sequences and joint positions to keep it even.

Sealing

Sealer is what keeps colour rich. Over time, sun and traffic wear the sealer, and colour looks faded and patchy. A clean and re-seal every few years restores it.

Refreshing faded colour

Faded coloured concrete that is otherwise sound can often be revived with cleaning and a tinted sealer. Badly worn areas may suit a coloured overlay.

Quotes

We bring colour samples on the visit, then send a written quote listing preparation, base, colour method, finish, joints and sealing.

Picking a colour that ages well

Colour oxides are mixed through the concrete, so the colour runs right through the slab rather than sitting on top. Even so, all coloured concrete softens a little as the surface weathers. Mid-tones such as slate grey, sandstone and gunmetal tend to age gracefully. Very dark colours look dramatic but show efflorescence, the white bloom that sometimes appears as concrete dries, more readily. Very light colours brighten shaded yards but show tyre marks and leaf stains. We bring colour chips to the visit so you can judge them against your home.

Broom finishes for grip

On sloping Ferntree Gully driveways, a coloured slab with a broom texture is a practical, grippy alternative to exposed aggregate. The broom lines run across the slope so tyres and shoes have something to hold.

Keeping colour consistent

Colour can vary slightly between truck loads and with curing conditions. We order the full quantity from one batch where possible, finish the whole area the same way and cure it evenly to keep the result consistent.

Sealing coloured concrete

A sealer protects colour from UV fade and stains and can refresh it years later.

Foothill ground, rain and councils

Ferntree Gully sits where the Knox plains run up into the Dandenong Ranges. Below the lawns on the lower streets you usually find heavy grey and orange clay that holds water through winter and splits open in a hot February. Higher up toward Upper Ferntree Gully, Upwey and The Basin, the soil is a stony, brown hillside clay over weathered rock, and the slopes send a surprising amount of water downhill every time it rains. Old cut-and-fill from earlier house builds adds another variable. We dig a test hole on every property, take the soft material out, rebuild with compacted crushed rock chosen for what we found, and shape the surface so water always has somewhere to go.

Inside your own boundary, most driveways, paths and patios need no permit. The crossover, kerb and council footpath always do, and that consent comes from Knox City Council for most of our area or the Shire of Yarra Ranges for Upwey and parts of Upper Ferntree Gully, Lysterfield and The Basin fringe. House slabs, large garages and many retaining walls go through a building surveyor with engineering. Bushfire and vegetation overlays affect parts of the hills. Your quote names whatever applies.

What our Ferntree Gully quotes spell out

You will not get a single number scribbled on a business card. Our written quote breaks the job into the pieces that actually drive the outcome: the area in square metres, breaking out and disposing of whatever is there now, how far down we dig, the class and depth of crushed rock, slab thickness and the steel inside it, the finish or stone blend you chose, the joint plan, each drain, pit and length of pipe, step and edge work, sealing, and any Knox or Yarra Ranges paperwork. If the site needs a line pump, a long barrow run or protection for a neighbour's driveway, that is listed too.

We keep square-metre rates off this website on purpose. In the foothills, the work hidden below the finished surface varies hugely between two blocks in the same street: one might be firm and flat, the next steep, wet and full of old fill. Pricing sight unseen means guessing, and a guess ends up either padded or short. After a visit we can price the real job.
