Average Cost Of Exposed Aggregate In Perth

Exposed aggregate driveways in Perth typically cost between $110 and $160 per square metre, fully installed. That range covers standard residential work on a well-prepared site. More complex jobs — sloping sites, tight access, large areas or premium aggregate blends — can push costs beyond $160 per m².

What Affects Exposed Aggregate Pricing

Understanding what drives the cost variation helps you assess quotes accurately:

  • Aggregate type — standard blends are cheaper; premium pebbles, coloured glass or imported stone cost more
  • Exposure depth — deeper exposure requires more careful washing at the right cure window, adding to labour time
  • Site preparation — rocky ground, tree roots or deep sand all add excavation and compaction costs
  • Slab thickness — driveways used by heavier vehicles need a thicker slab and more reinforcement
  • Access and site constraints — narrow gates or limited concrete truck access increase pour time and cost

Is Exposed Aggregate Worth The Cost

For most Perth homeowners, exposed aggregate is worth the price premium over plain concrete. Here is why:

  • Texture improves grip in wet weather, making it safer than smooth-finish concrete
  • The natural look of exposed pebbles ages better than plain or stencilled concrete
  • Durability is equivalent to plain concrete — the finish does not peel or deteriorate with normal use
  • It adds stronger kerb appeal than plain concrete, which can support property value

Exposed Aggregate vs Plain Concrete

If you are deciding between exposed aggregate and plain concrete, the key differences come down to cost and aesthetics:

  • Plain concrete: $80 – $130 per m²
  • Exposed aggregate: $110 – $160 per m²

The $30–$40 per m² premium buys you a textured, non-slip surface with a richer visual appearance. Over a 60 m² driveway, the difference is roughly $1,800–$2,400 — a relatively small amount when considered against a 25–30 year lifespan.

Frequently Asked Questions

Frequently Asked Questions

Helpful answers for Perth property owners planning concrete driveways, repairs, resurfacing and durable concrete surfaces.

How much does exposed aggregate cost per m2 in Perth?

Exposed aggregate in Perth typically costs between $110 and $160 per square metre installed. Premium aggregate blends or complex sites can push this higher.

How long does an exposed aggregate driveway last in Perth?

A properly installed exposed aggregate driveway in Perth will last 25–30 years or more. The exposed surface is no less durable than plain concrete when correctly installed and maintained.

Does exposed aggregate need sealing?

Sealing is recommended every 3–5 years to protect the aggregate and prevent staining. Sealing does not significantly increase the overall cost of ownership and helps maintain the appearance of the surface.

Can exposed aggregate be used on sloped driveways?

Yes. The textured surface of exposed aggregate makes it well suited to sloped driveways where grip is important. Contractors may charge a small premium for sloped sites due to additional formwork and finishing complexity.
