Exposed Aggregate Concrete in Noosa for Driveways, Pool Surrounds and Outdoor Areas
We pour and finish exposed aggregate concrete across Noosa Shire, from Noosaville and Tewantin out to Peregian Beach and up into the hinterland around Cooroy. The process is simple to explain and hard to fake. We place the concrete, screed and float it, then spray a surface retarder that stops the top layer of cement paste from setting. Once the slab underneath has firmed up, we wash that paste off with water and a broom to reveal the stones below. Timing that wash is the real skill. Go too early and you loosen the stones. Go too late and they stay buried.
Our climate shapes how we do the job. Summer storms can roll in during a pour, so we watch the radar, keep plastic sheeting on hand and plan pours around the afternoon weather where we can. High humidity means moss, mould and black algae grow fast on shaded concrete. That makes a good penetrating or acrylic sealer worth having on exposed aggregate here. Salt air near Sunshine Beach and Noosa Heads also attacks unsealed surfaces and any steel close to the top of the slab. We pay attention to reinforcement cover and sealing on coastal jobs for that reason.
Most people choose exposed aggregate because it hides the everyday mess. Sandy feet from the beach, tyre marks, leaf stains from the poinciana out the front. It also gives better grip than a steel-trowelled finish, which is why so many homeowners pick it for pool surrounds and sloping concrete driveways. If you want a smoother look in some areas, we can combine it with coloured and stamped concrete borders or bands so the whole outdoor area ties together.

How We Pour and Expose Aggregate Concrete in Noosa Shire
From base prep and formwork to the retarder wash and final seal
Step 1: Site Prep, Formwork and Falls
We dig out to the right depth, compact the base and check how water will drain off the finished surface. Formwork goes in with falls set away from the house and towards drains, which matters in our heavy summer rain. Reinforcing mesh is placed on bar chairs so it sits at the correct depth in the slab.
Step 2: Pouring and Placing the Aggregate Mix
The concrete arrives with your chosen stone blend already in the mix. We place it, screed it level and bull float the surface so the stones sit evenly just under the top. On some jobs we broadcast extra stone across the surface and press it in for a denser look.
Step 3: Retarder Spray and Exposure Wash
We spray a surface retarder over the fresh concrete so the top layer of cement paste stays soft. When the slab underneath has set enough, we wash and brush that paste away to expose the stones. We test small patches first to make sure the stones hold firm before washing the whole area.
Step 4: Saw Cutting, Acid Wash and Sealing
We saw cut control joints so any shrinkage cracking follows straight lines rather than wandering across the slab. Once the concrete has cured, we clean off any cement haze and apply a sealer. The sealer brings out the colour of the stones and helps resist mould, stains and salt air.
Why Exposed Aggregate Suits Noosa Homes and Holiday Rentals
Grip, low-fuss looks and a surface that handles our humid coastal climate
Better Grip Around Pools and on Slopes
The exposed stones give your feet and tyres something to hold onto. That helps on wet pool surrounds and on steep hinterland driveways after a storm. You get a surface that suits wet feet and wet weather much better than smooth concrete.
Hides Everyday Dirt and Wear
The mix of stone colours disguises sand, leaf litter, tyre marks and small stains. Your driveway looks tidy between cleans, even with beach trips and a holiday rental turnover every weekend. Plain grey concrete shows every mark by comparison.
Stands Up to Humid Coastal Conditions
A well-placed, properly sealed exposed aggregate slab copes well with our humidity, salt air and heavy rain. Sealing slows moss and mould growth in shady spots and makes cleaning easier. With resealing when the surface starts to look dull, it keeps its colour for years.

We Plan Pours Around Noosa Weather
Summer storms and humidity change how fast concrete sets and when we can wash it. We watch the forecast, keep covers on site and adjust our timing on the day. That care protects the finish you're paying for.
Careful Wash-Off Timing
The look of exposed aggregate comes down to washing at the right moment. We test small patches before exposing the whole slab so stones stay locked in. You end up with an even reveal across the surface.
Coastal and Hinterland Know-How
Sandy coastal blocks at Sunshine Beach and clay sites around Cooroy need different base prep. We set falls and drainage to suit your block and our heavy rain. That helps stop ponding, washouts and movement down the track.
One Crew for the Whole Outdoor Job
We pour driveways, paths, patios, slabs and permeable paving as well as exposed aggregate. That means your driveway, pool surround and side path can be planned and finished together. You deal with one team from dig-out to sealing.
Exposed Aggregate Questions From Noosa Homeowners
Common questions answered
How much does exposed aggregate cost compared to plain concrete in Noosa?
Exposed aggregate usually costs more than a plain broom finish because of the stone mix, retarder, washing and sealing. The final price depends on the area, slab thickness, access for the concrete truck or pump, how much dig-out is needed and the stone blend you choose. We give you a written quote after looking at the site.
What happens if it rains on the day of my pour?
Heavy rain on fresh exposed aggregate can wash out the retarder and damage the surface. We check the forecast closely and will move the pour if a storm is likely. If a shower comes through unexpectedly, we cover the work with plastic sheeting to protect it.
How often should I reseal exposed aggregate in a humid climate?
It depends on sun exposure, foot and car traffic, and how close you are to the beach. A good sign is when the stones look dull and water stops beading on the surface. We can clean and reseal it for you when that happens.
Can you turn my old plain concrete driveway into exposed aggregate?
You can't expose stones in concrete that has already set, so the old slab needs to come out or be overlaid. If your existing driveway is cracked or sunken, we usually recommend removal and a new pour with a proper base. We'll look at the slab and talk you through the options.
How do I keep moss and black mould off my exposed aggregate?
Keep it sealed, sweep off leaves regularly and avoid letting garden beds drain across it. In shady spots, a gentle clean with a suitable concrete cleaner helps before mould takes hold. Be careful with high-pressure washers held close to the surface, as they can strip sealer and loosen stones.
