Exposed Aggregate Concrete in Perth: Costs and What to Expect

Exposed aggregate is Perth's most popular premium driveway and patio finish — a textured, decorative concrete surface that reveals the natural stone within the mix. It looks great, hides dirt well, and provides excellent slip resistance.

How Is Exposed Aggregate Made?

After the concrete is poured and levelled, a chemical retarder is applied to the surface to slow the curing of the top layer. The retarder is washed off the next day, revealing the aggregate (stones) within the mix. The result is a textured surface with stones embedded throughout.

Exposed Aggregate Costs in Perth

Expect to pay $90–$130 per m² for standard exposed aggregate. The variation in price depends on the aggregate mix (imported pebbles cost more than local stone), area size (larger areas cost less per m²), and site access. A standard 40m² double driveway runs $3,600–$5,200 installed.

Choosing Your Aggregate Mix

Perth concreters typically offer river pebble (warm tones), white quartz (bright, clean look), charcoal basalt (modern), and multi-colour blends. Ask to see samples on a completed job before committing, as wet concrete looks different to cured concrete.
