What Is Exposed Aggregate Concrete?
Exposed aggregate concrete is a decorative form of concrete where the surface cement paste is removed — during or shortly after placement — to reveal the natural stones, pebbles, and aggregates embedded within the mix. The result is a textured, visually distinctive exposed concrete finish that immediately sets a project apart from plain grey concrete.
The process works by applying a surface retarder to slow the curing of the top layer, then washing it away to uncover the aggregate below. What’s left is a surface rich in natural colour and texture — smooth river pebbles, crushed quartz, granite chips, or a custom stone blend, depending on the mix selected.
This approach delivers two important benefits in one finish. Aesthetically, it produces a natural stone appearance with real depth and character that complements both modern and traditional Australian homes. Functionally, the raised texture of the exposed stones creates a slip-resistant surface that performs safely in wet conditions, making it ideal for high-traffic outdoor areas. It’s a strong, durable concrete finish built to handle decades of Australian weather.
What Is Aggregate Concrete?
Aggregate concrete is made from four core ingredients: cement, sand, water, and aggregates. Aggregates — which include materials like crushed rock, gravel, and natural stone — make up the bulk of the mix. They’re what give concrete its structural integrity, bearing capacity, and density.
Without aggregates, concrete would lack the strength to perform under the loads placed on driveways, slabs, pathways, and construction projects. The size, shape, and hardness of the aggregates directly influence the finished product’s durability and surface characteristics.
When aggregates are selected for their visual appeal and then intentionally exposed at the surface, the result is decorative exposed aggregate concrete. Broadmix is a trusted supplier of quality aggregate concrete mixes across Victoria, offering products designed for consistent strength, reliable workability, and exceptional surface finish.

- Site preparation — Excavation, compaction, and sub-base installation to create a stable foundation.
- Concrete mix preparation — The selected aggregate mix is batched and prepared to specification.
- Pouring and levelling — Concrete is poured, screeded, and levelled to the required surface grade.
- Surface retarder application — A chemical retarder is applied to the surface to slow the setting of the cement paste on top.
- Washing to expose aggregates — Once the body of the concrete has cured sufficiently, the surface is washed to remove the retarded paste and reveal the aggregate below.
- Sealing and curing — A quality sealer is applied to protect the surface, enhance colour, and extend the life of the finish.
