Exposed Aggregate Concrete in Baldivis
Imagine a driveway or outdoor area where the colour and texture of the stone show through instead of a plain grey surface. Exposed aggregate concrete removes the top cement layer to reveal the decorative stones underneath, giving a hard-wearing finish that works well on residential properties in Baldivis and surrounding areas.
We install exposed aggregate concrete for your driveways, patios, pathways and outdoor living spaces. The textured surface hides minor marks and gives better grip when wet than a smooth broom finish. Every job starts with correct base preparation and drainage falls so the concrete holds up under local conditions.
How the finish is created
After the concrete is poured and levelled, a retarder is applied to the surface. Once the concrete has set enough, the top cement paste is washed away to expose the stones. The size and colour of the aggregate can be chosen to suit the property. Smaller stones give a finer look while larger stones create more texture.
The surface is then sealed. Sealing protects the stones from staining and helps the colour last longer. Most exposed aggregate surfaces benefit from cleaning and resealing every two to three years, depending on traffic and sun exposure.
Where exposed aggregate works well
Exposed aggregate suits areas that see regular use and need a durable surface. It is commonly used for:
- Residential driveways
- Patios and alfresco areas
- Pathways
- Pool surrounds and outdoor living spaces
If you also want a matching concrete driveway or concrete patio in the same finish, we can pour both at the same time so the front and back of the property look consistent.
Preparation and installation
The finish depends on the base work as much as the final wash. We excavate to the required depth, compact the base, and set formwork and drainage falls before any concrete is poured. Steel reinforcement is placed on chairs so it sits in the middle of the slab. On sandy soils common in Baldivis and nearby estates, proper compaction reduces the chance of movement later.
Once poured, the surface is levelled and the retarder is applied at the right time. The wash is done when the concrete has set enough to hold the stones but still allows the top cement to be removed cleanly.
Exposed aggregate versus other finishes
Exposed aggregate leaves the stones slightly raised, which gives texture and grip. Honed concrete uses a similar stone mix but is ground flat for a smoother surface that suits undercover areas. Liquid limestone is a different mix that stays cooler underfoot and is often chosen for pool surrounds.
A new exposed aggregate pour gives a consistent stone finish across the whole area. If the existing surface is still sound but only needs a surface refresh, other options may be discussed on site.
Frequently Asked Questions
Standard concrete has a smooth or broom finish. Exposed aggregate washes away the top cement layer so the decorative stones show through, creating a textured surface with more grip.
