Exposed Aggregate Driveways
Exposed aggregate is poured like an ordinary driveway, then the surface is washed back to reveal the decorative stone within the mix. The result is a textured, non-slip finish with far more character than plain grey concrete.
Pricing guide: How much more does exposed aggregate cost?
Expect roughly 25 to 50 per cent more than plain concrete, reflecting the decorative stone and the extra washing and sealing work.
Why homeowners choose it
- Distinctive finish that lifts the look of a property
- Naturally slip-resistant, which suits slopes and pool surrounds
- Hides dirt and tyre marks better than plain concrete
- Same structural durability as a standard slab
- A wide range of stone colours and sizes to choose from
How it works
-
1
Preparation
The area is excavated, based and formed exactly as for a standard driveway.
-
2
Pour
Concrete containing the chosen decorative aggregate is poured and screeded.
-
3
Surface retarder
A retarder is applied so the very top layer of cement stays soft while the slab sets beneath.
-
4
Exposing
The surface is washed back the following day to reveal the stone.
-
5
Seal
Once cured the surface is sealed, which deepens the colour and makes cleaning easier.
Hiring guide
Questions worth asking before you commit to a contractor.
Ask to see it, not just take their word for it. Insurance protects your property if something goes wrong on site.
Site preparation, disposal of old material, and any council permits can be included or charged separately — get it in writing before you compare quotes.
Some contractors do the work themselves; others subcontract parts of it. Neither is wrong, but you should know who is doing your job.
Old concrete, tree roots or drainage issues are common surprises. Ask how a change of scope gets costed before it happens, not after.
Materials usually carry a manufacturer's warranty. Ask specifically about the contractor's own workmanship warranty too.
Frequently asked questions
How much more does exposed aggregate cost?
Expect roughly 25 to 50 per cent more than plain concrete, reflecting the decorative stone and the extra washing and sealing work.
Is it hard to keep clean?
No harder than plain concrete once sealed. The texture actually hides marks well. Give it an occasional hose or pressure wash.
How often does it need resealing?
Every three to five years depending on sun and traffic. Resealing keeps the colour rich and stops the surface absorbing stains.
Is it slippery when wet?
Less so than smooth concrete. The exposed stone gives good grip, which is why it is popular around pools and on sloped drives.
