Maintenance Tips for Exposed Aggregate Concrete

With the right care, exposed aggregate concrete will look great and perform well for decades. Follow these straightforward maintenance steps:

Reseal every 2–3 years

Resealing protects the surface from UV damage, staining, and moisture penetration. The frequency depends on traffic levels and exposure.

Clean with pressure washing

A regular pressure wash removes built-up dirt, algae, and surface grime without damaging the aggregate or sealer.

Avoid harsh chemicals

Strong acid-based cleaners can strip the sealer and damage the cement matrix. Use pH-neutral cleaning products.

Repair cracks early

Small cracks addressed promptly prevent water ingress, which can cause the crack to grow over time — particularly during freeze-thaw cycles.

Straight Answers

Questions We Hear From Donnybrook Customers

What concrete strength do I need for a residential driveway or house slab?

A typical residential driveway is 25 MPa, sometimes 32 MPa for heavier use or commercial-grade work. House slabs are engineer-specified the structural drawings will state the MPa, slump and reinforcement. We won’t guess on a structural slab, but for paths, shed pads and standard driveways we can recommend based on the application.

Is permeable concrete an option if my estate's planning permit requires water-permeable surfaces?

Often yes many new Donnybrook permits call for permeable surfacing on driveways and paths to meet stormwater conditions. Permeable concrete is one of several options. Whether it suits your slab depends on the substrate, the loading and long-term maintenance. Send through the permit condition and we’ll talk it through.

How long should I wait before sealing an exposed aggregate driveway?

Most sealers want 28 days of cure before application so the slab has finished its initial moisture loss. Some water-based sealers allow earlier check the product datasheet. Sealing too early traps moisture and you’ll see it bloom under the surface within months. Better to wait.

Can you supply a pour into a tight new-estate block with restricted truck access?

Yes a lot of our Donnybrook work is in newer estates with narrow service roads and shared driveways. Where the truck can’t reach, we coordinate with a line pump. Tell us the site conditions when you book and we’ll confirm the right setup.

What happens to leftover concrete at the end of a pour?

A small over-order is normal better than coming up short and needing a second truck for half a cubic metre. Anything unused returns to the plant for wash-out. If you’ve got a use for the extra (a step, a small pad, post footings), have it formed up so the crew can place it before the truck leaves.

Do you batch on weekends for residential pours?

Yes Saturday and Sunday delivery is available, and plenty of owner-builder driveway pours happen on weekends specifically because that’s when the homeowner can be on site. Book a couple of days ahead so dispatch can load the run correctly.
