Exposed Aggregate Concrete in Nambour for Driveways, Paths and Pool Surrounds
We lay exposed aggregate concrete across Nambour and the surrounding hinterland. It suits homeowners who want a hard-wearing, textured finish that looks better than plain grey. We pour a mix with decorative stone through it, then apply a surface retarder so the top layer of cement paste stays soft while the slab underneath sets. Once the timing is right, we wash that paste away with a pressure washer and stiff brooms to reveal the stone. The result is a grippy, natural-looking surface that hides tyre marks, leaf stains and red dirt far better than a smooth finish.
Local conditions shape how we do every job. Summer storms can dump heavy rain in a short time, so we plan falls, edges and drainage before the boxing goes in. Steep blocks in the hinterland also mean we often place exposed aggregate on concrete driveways where tyre grip matters in wet weather. Reactive clay soils move between wet and dry spells. That is why we compact a proper road base, use steel reinforcement and cut control joints in the right places to manage cracking.
High humidity is hard on decorative concrete. Mould, algae and black lichen spots grow on unsealed or worn surfaces, especially under trees or along shaded side paths. We seal exposed aggregate once it has cured enough, and we choose sealer with our humidity in mind so it does not turn cloudy or white. If you want the same finish carried through your backyard, we can match it on paths and patios so the whole property ties together.

How We Pour and Wash Exposed Aggregate Concrete
From base preparation to the final seal, here is what happens on site
Step 1: Excavation, Base and Boxing
We dig out to the right depth, remove soft soil and compact a crushed road base. We set up formwork to the levels and falls needed to shed storm water away from your house. Reinforcement mesh goes in on bar chairs so it sits in the middle of the slab.
Step 2: Pouring and Screeding the Aggregate Mix
The concrete arrives with your chosen stone blended through it, or we seed extra stone onto the surface for a denser look. We screed it to level, bull float it and tamp the stone just below the surface. Getting the stone evenly spread now decides how good the finished surface looks.
Step 3: Applying Retarder and Washing Off
We spray a surface retarder over the fresh concrete so the top layer stays workable while the slab below hardens. When the concrete is ready, we wash the soft paste away with a pressure washer and brooms. Timing matters here, and in humid weather we check the surface closely rather than going by the clock.
Step 4: Saw Cutting, Cleaning and Sealing
We saw cut control joints to guide any shrinkage cracks into straight lines. After curing, we acid wash or clean off any cement haze and let the surface dry properly. We then roll or spray on sealer to bring out the stone colour and protect against mould and staining.
Why Exposed Aggregate Works for Nambour Properties
Practical advantages for wet weather, steep driveways and busy households
Better Grip on Wet and Sloping Surfaces
The exposed stone gives tyres and shoes something to grip. That matters on steep driveways and around pools after a summer downpour. Plain trowelled concrete can get slick when wet, especially once moss starts to grow.
Hides Everyday Stains and Wear
The mix of stone colours disguises tyre marks, oil drips, leaf stains and red soil tracked in from the garden. You spend less time scrubbing to keep it looking clean. Minor scuffs blend into the texture instead of standing out.
A Finish That Suits Hinterland Homes
Natural stone sits well with timber Queenslanders, acreage homes and lush gardens. You can carry the same finish from the driveway to paths, patios and pool areas. It adds a finished look to the outdoor spaces you use every day.
Exposed Aggregate Concreting Built for Hinterland Conditions
We Know Hinterland Slopes and Soils
Many local blocks are steep, with clay soils that move between wet and dry spells. We set the base, reinforcement and joints with that in mind. We also plan grip and drainage for driveways that climb a hill.
Careful Wash-Off Timing
Wash too early and stones pull out. Wash too late and the paste will not come off evenly. We watch the surface closely on pour day, adjusting for heat and humidity to get a clean, even reveal.
Drainage Planned Before We Pour
Heavy summer storms will find any low spot. We set falls away from your house and add grated drains or edge details where water needs somewhere to go. If your site needs it, we can also talk you through permeable paving options.
Sealer Chosen for Local Humidity
Some sealers go cloudy or white when they trap moisture in humid conditions. We pick products and application timing that suit our climate. That helps your stone stay clear and protected for longer.
Exposed Aggregate Questions from Nambour Homeowners
Common questions answered
What affects the cost of an exposed aggregate driveway in Nambour?
The main factors are the area, site access, how much digging and base work is needed, and the stone you choose. Steep blocks, removing an old driveway or adding drains all add work. We measure on site and give you a written quote based on your actual job.
Can I turn my existing plain concrete into exposed aggregate?
Not really. The stone has to be in the concrete when it is poured, so an existing slab cannot be washed back to look the same. If your old concrete is cracked or sunken, we can remove it and pour a new exposed aggregate surface.
How long before I can walk or drive on new exposed aggregate?
It depends on the weather, the mix and how the concrete cures. Foot traffic comes well before cars, and heavy vehicles need to wait longest. We will give you clear advice for your job before we leave site.
Why does exposed aggregate get black spots or go green in Nambour?
Our humidity and rain let mould, algae and lichen grow, particularly in shady spots under trees. A good sealer slows this down, and a gentle clean followed by resealing usually brings the surface back. Avoid blasting it with a very high-pressure nozzle up close, as that can damage the sealer and loosen stones.
How often does exposed aggregate need resealing?
That depends on sun exposure, traffic, shade and the sealer used. Signs it is due include water soaking in instead of beading, the stone looking dull, or mould returning quickly after a clean. We can inspect it and reseal when it needs it.
