What Is Exposed Aggregate Concrete?
Exposed aggregate concrete is created by removing the top layer of cement paste to reveal the natural stones (aggregates) underneath. This gives the surface a textured, decorative finish.
Instead of a smooth grey slab, you get a mix of stone colours and textures that stand out. This is why it’s commonly used for:
- Exposed aggregate driveways
- Concrete patios
- Pool surrounds
- Footpaths and walkways
It’s sometimes referred to as washed aggregate concrete or exposed finish concrete, and it’s a popular choice in Darwin due to its combination of durability and appearance.
Why Choose Exposed Aggregate in Darwin NT?
Darwin’s climate can be harsh on outdoor surfaces. Heat, rain, and heavy use all take a toll. Exposed aggregate is well suited to these conditions.
Strong and Long-Lasting
The exposed stones create a tough surface that handles traffic better than standard concrete finishes.
Slip-Resistant Surface
The textured finish provides extra grip, making it a practical option for driveways, paths, and pool areas.
Low Maintenance
Once sealed, exposed aggregate is easy to clean and doesn’t require constant upkeep.
Visual Appeal
With different stone sizes and colours available, you can customise the look to suit your property.
Exposed Aggregate Driveways
An exposed aggregate driveway is one of the most common upgrades homeowners choose. It replaces plain concrete with a finish that adds character while still being practical.
We install:
- Aggregate concrete driveways for new homes
- Replacement exposed concrete driveways
- Extensions to existing driveways
- Custom layouts and edging
Compared to a plain slab, an aggregate driveway stands out visually while still handling daily vehicle use. It also helps reduce the appearance of stains and wear over time.
If your current driveway is cracked or outdated, replacing it with an exposed driveway can improve both function and street appeal.
Exposed Aggregate for Patios & Outdoor Areas
Outdoor living is a big part of life in Darwin. Exposed aggregate works well for patios because it combines durability with a more refined finish.
It’s commonly used for:
- Outdoor entertaining areas
- Alfresco spaces
- Garden seating areas
The textured surface helps prevent slipping, especially during wet conditions. It also stays visually consistent over time, even with regular use.
Exposed Aggregate Walkways & Footpaths
Footpaths and walkways benefit from the grip and durability of exposed aggregate.
We install:
- Garden paths
- Side access walkways
- Entry paths to homes
Using exposed aggregate for walkways creates a consistent look across your property, especially if it matches your driveway or patio.
Exposed Aggregate Slabs
For homeowners building or extending, exposed aggregate slabs offer a decorative alternative to plain concrete.
These slabs can be used for:
- Shed bases
- Outdoor structures
- Seating areas
- Small courtyards
They provide the same structural strength as standard concrete, but with a more finished appearance.
Pool Surrounds with Exposed Aggregate
Pool areas need a surface that is both safe and durable. Exposed aggregate is a practical option for this environment.
Key benefits include:
- Better traction around wet areas
- Resistance to wear from water and chemicals
- A cooler surface compared to some finishes
This makes it a suitable choice for pool surrounds in Darwin homes.
Installation Process
The installation of exposed aggregate concrete typically follows a straightforward, step-by-step approach:
- Site Inspection
The area is assessed, measurements are taken, and layout and finish preferences are determined. - Ground Preparation
The site is cleared and prepared to create a solid base, which is essential for long-term durability. - Formwork & Reinforcement
Formwork is set up to define the shape and structure, with reinforcement added where required. - Concrete Pouring
The aggregate concrete mix is poured and spread evenly across the surface. - Exposure Process
The top layer is carefully washed back to reveal the embedded stones, creating the exposed aggregate finish. - Sealing
Once cured, the surface is sealed to protect it and enhance its appearance.
Repair & Resurfacing Options
If you already have concrete in place, you may not always need a full replacement.
We offer:
Concrete Repairs
Fixing cracks, chips, and damaged sections to restore the surface.
Concrete Resurfacing
Applying a new layer or finish over existing concrete, including exposed-style finishes where suitable.
This can be a more cost-effective way to refresh older surfaces without removing everything.

Cracks in concrete are usually caused by ground movement, temperature changes, poor concrete preparation, or heavy loads. Minor cracks are common and can often be fixed with concrete repair or sealing before they worsen.
