Local West Gippsland concreting specialists. Residential and rural jobs, free on-site quotes, quality finishes built to last.
Exposed aggregate is one of the most popular decorative concrete finishes in Warragul and across Baw Baw Shire, and for good reason. It reveals the stones in the concrete mix to create a textured, natural surface with excellent slip resistance, making it a practical and attractive choice for driveways, paths, patios and pool surrounds.
The finish is created by washing away the top layer of cement paste to expose the stones underneath, then sealing the surface to bring out the colour and protect against staining. We handle the full process, from the base preparation to the final seal, so your exposed aggregate surface looks sharp and performs well on West Gippsland ground for years.
What exposed aggregate is
Exposed aggregate is a decorative concrete finish where the top layer of cement paste is removed to reveal the stones, or aggregate, in the mix. The result is a textured surface with the natural colour and shape of the stones showing through, giving a decorative look that is also highly practical. The texture provides excellent slip resistance, making it a popular choice for surfaces that get wet, like driveways, paths and pool surrounds.
The finish is created by pouring the concrete, letting it set to the right firmness, then washing or brushing away the surface paste to expose the stones. The depth of exposure can be varied, from a light reveal that shows just the tops of the stones to a deeper exposure that shows more of their shape and colour. We control the exposure to give the look and the texture you want.
Local stone colour options
The colour of exposed aggregate comes from the stones in the mix, and there is a range of options available, from warm earth tones to cool greys and blues. The stones are sourced from local quarries, so the colours reflect the natural geology of the region. We can show you samples of the available stone blends and help you choose one that complements your home and your landscape.
The cement paste can also be coloured with oxide to give a background tone that sets off the stones, from a warm cream to a charcoal grey. The combination of stone colour and paste colour gives a wide range of looks, from a natural, earthy surface to a bold, modern contrast. We discuss the options during the free site visit and help you choose the right blend for your property.
Driveways, patios and pool surrounds
Exposed aggregate is a versatile finish that suits a range of surfaces. On a driveway, the texture gives excellent grip in wet weather, and the natural stone look complements both modern and traditional homes. On a patio, exposed aggregate gives a decorative, non-slip surface that is comfortable to walk on and easy to clean.
Around a pool, the texture of exposed aggregate gives grip on a wet surface, making it a safe and practical choice for pool surrounds. The sealed surface is resistant to pool chemicals and salt, and the continuous pour means no joints for water to penetrate. We can adjust the depth of exposure and the sealer to suit the location, giving more grip on a pool surround or a lighter texture for a patio where people walk barefoot.
Can exposed aggregate go over existing concrete?
Exposed aggregate can be applied over an existing concrete surface, but only if the old concrete is sound, level and free of major cracks. A thin exposed aggregate overlay is a specialised product that bonds to the existing slab and gives the look of exposed aggregate without a full pour. It is a good option for a driveway or patio that is structurally sound but has a tired or plain surface.
An overlay is not a fix for structural cracks, lifting or settling, as it will follow the shape of the underlying slab. For a surface with structural damage, a full replacement is the better option. We assess the existing slab on site and give you honest advice on whether an overlay or a full pour is the right choice for your situation.
Slip resistance in Gippsland wet weather
Slip resistance is one of the main reasons people choose exposed aggregate, and it is especially important in West Gippsland, where close to 900 millimetres of rain falls in a typical year. The texture of the exposed stones gives a non-slip surface that is far safer than a smooth trowelled finish when wet, making it the standard choice for driveways and paths on sloped blocks.
The level of slip resistance depends on the depth of exposure and the type of stones in the mix. A deeper exposure gives more grip, while a lighter exposure is smoother but less slip-resistant. We can adjust the exposure to suit the location, giving more grip on a sloped driveway or a pool surround, and a lighter texture on a patio where comfort matters more than grip.
Downsides and how we avoid them
Exposed aggregate has a few downsides that are worth knowing. The texture can be rough underfoot, especially for bare feet, which is a consideration for patios and pool surrounds. The surface can also be harder to clean than a smooth finish, as dirt can settle in the texture. And if the sealer wears off, the surface can look dull and be more prone to staining.
We address these downsides by adjusting the exposure to suit the use, using a lighter texture for patios and pool surrounds, and by sealing the surface with the right product. A quality sealer fills the texture slightly, making the surface smoother and easier to clean, while still maintaining grip. We also recommend resealing every two to four years to keep the surface protected and looking its best.
Popular colours and finishes
The most popular exposed aggregate colours in Warragul reflect the natural tones of the region. Warm earth tones, from sandy beige to rich brown, complement brick and timber homes and blend with the West Gippsland landscape. Cool greys and blues suit modern homes with render or cladding, and charcoal gives a bold, contemporary look that hides oil and dirt well.
The sealer also changes the final look, from a natural matte finish that lets the stones speak for themselves to a wet-look gloss that deepens the colour and gives a shiny surface. We can show you samples of each sealer type and help you choose the right one for your property. The combination of stone blend, paste colour and sealer gives a wide range of looks, and we help you find the right one.
Sealing and maintenance
Sealing is the key to maintaining exposed aggregate, and we seal every exposed aggregate surface we pour. The sealer brings out the colour of the stones, protects against oil and organic stains, and makes cleaning easier. We recommend resealing every two to four years depending on exposure and traffic. See our concrete sealing page for more on sealer types and resealing schedules.
Day-to-day maintenance is simple: a regular sweep and an occasional wash with a hose or pressure cleaner, using a wide-angle nozzle, is all that is needed. Keep drains clear of leaves and silt so water does not back up against the slab edge. If you notice a crack developing, have it assessed early, as a routed and sealed crack is a simple repair that stops water entry and prevents the crack from spreading.
Step-by-step process
Every exposed aggregate job starts with a free on-site quote. We come to your property, look at the ground, the access and the levels, and talk through the stone blend, colour and finish you want. We assess the soil, measure the area, note any drainage issues, and show you samples of stone blends and sealers. You get honest advice and a clear quote that reflects your actual site.
On pour day, we prepare the base, set the formwork, lay the reinforcement, and pour and screed the concrete. We then apply a surface retarder, let the concrete set to the right firmness, and wash away the surface paste to expose the stones. After the concrete has cured, we clean the surface, cut the control joints, and apply the sealer. The whole process is typically completed in two to three days, and the surface is walkable within a day of sealing.
