Exposed Aggregate Concrete Finishes in South Brisbane and Logan

What Is Exposed Aggregate Concrete?

Exposed aggregate is a decorative concrete finish where the surface layer of cement paste is removed to reveal the natural stone beneath. The result is a textured, non-slip surface that showcases the colour and character of the aggregate stones embedded within the concrete.

This finish combines the structural strength of a full concrete slab with the visual appeal of natural stone, without the maintenance headaches of pavers or loose gravel.

How We Install Exposed Aggregate

David and the Bunce Concrete team follow a precise process refined over 18 years of concreting across South Brisbane and Logan.

First, we prepare the site with proper excavation, compaction, and formwork. We pour the concrete with your chosen aggregate blend mixed through the full slab depth, not just scattered on top. This ensures lasting durability rather than a cosmetic surface that chips away.

After pouring, we apply a surface retarder that slows the curing of the top layer. At exactly the right moment, we pressure-wash the surface to expose the aggregate stones beneath. Timing is critical here. Wash too early and the stones pull loose. Wait too long and the surface will not expose cleanly. This is where experience makes all the difference.

Once cured, we apply a quality penetrating sealer to protect the surface and enhance the stone colours.

Built for Queensland Conditions

South-east Queensland throws everything at outdoor concrete: harsh UV, torrential summer rain, and ground movement from reactive clay soils. Exposed aggregate handles all of it.

The natural stone surface resists fading from UV exposure far better than coloured or stamped concrete finishes. The textured profile channels water effectively, reducing pooling on driveways and pathways. Proper steel reinforcement and control joints, which David specifies for every job, manage the ground movement common in the Logan and Springwood area.

What Affects the Cost

Several factors influence the price of your exposed aggregate project:

• Site access and preparation — sloping blocks or poor soil require extra work
• Slab size and thickness — larger areas and thicker slabs use more material
• Aggregate selection — premium stone blends cost more than standard options
• Formwork complexity — curved edges or stepped levels add labour
• Drainage requirements — some sites need additional drainage solutions
