How exposed aggregate is made
Exposed aggregate is concrete with decorative stone mixed through it. After the pour, the stone is brought to the surface and the top layer of cement is removed to reveal it.
1. Mix selection
We choose an aggregate blend for the colour, size and texture you want, matched to your home.
2. Pour and place
Concrete is poured over a compacted, reinforced base, levelled, and the stone worked evenly to the surface.
3. Surface retarder
A retarder slows the top few millimetres from setting while the concrete below cures normally.
4. Wash and expose
At exactly the right moment the surface is washed back to reveal the stone. Too early or too late and the finish suffers — this is where experience counts.
5. Cut and seal
Control joints are cut to manage cracking, then the surface is cleaned and sealed.
Why the concreter matters
An experienced exposed aggregate concreter knows how to pick a mix that suits the site, apply retarder for an even finish, and build a structurally sound slab that cures properly. Cameron and his son are on every job — no rotating subcontract crews — so the same standards are applied from the first peg to the final seal.
We give honest advice on what will and won't work on your site, and a clear, itemised quote before any work starts.
Where we use exposed aggregate
The same finish works right across a property, so your outdoor areas can tie together:
Driveways
Hard-wearing, low-maintenance and the most popular use. See our exposed aggregate driveways page for mixes and design options.
Paths and walkways
From straight front paths to curved garden walks that tie into the driveway.
Patios and entertaining areas
A durable, attractive base for outdoor dining, alfresco and fire-pit zones.
Pool surrounds
Naturally slip-resistant underfoot — a practical, good-looking choice around water.
Commercial spaces
Forecourts, car parks and pedestrian areas that need to look good under heavy use.
Caring for exposed aggregate
Exposed aggregate is low maintenance, not no maintenance. Hose or pressure-wash it to remove dirt, avoid acids and bleach which can damage the surface, and reseal every few years to protect it from moisture, stains and UV. If a crack ever appears, get it looked at early — we can advise on repairs.

Frequently asked questions
What is exposed aggregate concrete?
It's decorative concrete where the top layer of cement is washed away to reveal the natural stone mixed through it, giving a textured, stone-like finish that is durable and slip-resistant.
How do concreters get the textured finish?
A surface retarder is applied after the pour to stop the top layer setting. Once the concrete beneath has firmed, the surface is washed back to expose the stone. Timing the wash is the critical skill.
Is exposed aggregate good around a pool?
Yes. The exposed stone gives good grip underfoot when wet, and lighter mixes stay cooler in summer. We plan drainage so water runs away from the pool and the house.
Do you do commercial exposed aggregate work?
Yes, we take on commercial forecourts, paths and outdoor areas as well as residential work. Call us to talk through the scope.
