The finishes
Exposed aggregate, honed, polished and burnished concrete, chosen to suit your home and budget.
Approved installer
We're an approved installer of Geostone Holcim, so your exposed aggregate is laid and finished to the manufacturer's standard.
What's included
What decorative / architectural concrete covers
Exposed aggregate
Stones revealed in the surface for a textured, hard-wearing, high-end decorative finish.
Polished & honed concrete
Smooth, modern floors and surfaces with a subtle sheen, ideal for alfresco areas and interiors.
Architectural floating steps
Cantilevered concrete steps that create a clean, contemporary entrance or level change.
Feature slabs & benchtops
Bespoke concrete benchtops, hearths and feature slabs finished to your design.
Concrete & landscape packages
We can package your concrete work with the surrounding landscaping, like floating steps or a driveway finished together with the landscaping around it — cheaper and more hassle-free than coordinating separate trades.
Outdoor features
Custom curved bench seats, fire places, stepping stones and more. We build all formwork in situ, so we're not limited to standard shapes — any size, dimension or shape can be built to your design.
What decorative concreting is
Decorative concreting is any concrete finished to look like a feature rather than a plain grey slab. The most popular is exposed aggregate, where the top layer of cement is washed back to reveal the stones set in the concrete, giving a textured, hard-wearing surface that suits driveways, paths and pool surrounds. See our full exposed aggregate pricing breakdown for real per square metre rates and what moves the price. Polished and honed finishes create a smoother, modern look for alfresco areas and interiors, and architectural floating steps add a clean, contemporary entrance — see how architectural and decorative concreting differ if you’re not sure which term applies to your job. If you’re weighing it up against a plain or coloured driveway, see our driveway options comparison.
The Geostone process
As an approved installer of Geostone Holcim, a typical residential job takes 4 to 6 days, laid and finished to the manufacturer’s standard:
- Days 1–2: Preparation. Excavation, site prep, steel fixing and formwork.
- Days 3–4: Pour and wash. The concrete is poured, then the top layer is washed back to expose the aggregate.
- Days 5–6: Acid wash and seal. The surface is acid washed, then finished with a penetrating sealer that lasts 5 to 10 years (less on high-traffic driveways). On driveways or slabs with a big slope, we also add a non-slip additive to boost the grip.

Choosing the right finish
The best finish depends on where it’s going, how much traffic it gets and the look you’re after. When we come to quote, we bring a range of exposed aggregate samples with us so you can see and touch each mix and picture how it’ll look laid in your driveway, path or backyard. Not sure what it’ll cost? See our exposed aggregate cost guide for real prices, or our driveway options comparison if you’re still deciding between finishes.
