✨ Exposed Aggregate Concrete – Strength Meets Style

Looking for a driveway or outdoor area that stands out? Exposed aggregate concrete combines durability, texture, and modern design in one finish. It’s one of the most sought-after concrete styles across North Brisbane and the Moreton Bay region, and it’s a specialty of K & Co Contracting.

💎 What Is Exposed Aggregate?

Exposed aggregate is a decorative concrete finish where the top layer of cement paste is removed to reveal the natural stones and pebbles within the mix. The result is a high-end, textured surface that’s both visually striking and naturally slip-resistant.

Each project is unique — no two slabs look exactly the same. You can choose from a wide range of stone colours, textures, and sizes, allowing you to match your home’s exterior perfectly.

🏡 Where It’s Commonly Used

Driveways and crossovers
Pool surrounds and patios
Pathways and entrances
Courtyards and outdoor entertaining areas
Commercial forecourts and walkways

Exposed aggregate gives any outdoor space a designer finish while standing up to Queensland’s climate.

⚙️ Our Installation Process

At K & Co Contracting, our process ensures a consistent, long-lasting result:

Preparation & Formwork – The site is excavated, compacted, and set out to the correct levels.
Concrete Placement – We pour high-strength concrete with your chosen aggregate blend.
Surface Retarder Application – A retarder is sprayed on to keep the surface paste soft while the concrete cures.
Exposing the Aggregate – Once cured, the surface is carefully washed or pressure-cleaned to reveal the stones beneath.
Sealing & Protection – Finally, we apply a premium sealer that deepens the colour and protects the surface from stains, UV, and weather.

🌈 Customisation Options

Your exposed aggregate can be fully tailored to your design preferences:

Aggregate choices: natural river stones, granite, quartz, shells, or even coloured glass.
Colour tones: from warm earthy hues to contemporary greys or bold contrasts.
Finish options: light, medium, or full exposure depending on the texture you prefer.

We work closely with suppliers such as Neilsen’s and Boral to offer premium local mixes suited for driveways, paths, and pool surrounds.

🧼 Maintenance & Longevity

With proper care, exposed aggregate concrete can last 30 years or more. To keep it looking its best:

Rinse or pressure-wash periodically to remove dirt and grime.
Reseal every 2–3 years to maintain colour and surface protection.
Avoid harsh chemicals or acidic cleaners that can dull the surface.

When sealed correctly, it remains slip-resistant, low-maintenance, and fade-resistant, even under heavy use.

💰 Cost & Value

Exposed aggregate costs slightly more than plain concrete, but it delivers far more in curb appeal, slip resistance, and longevity.
Many homeowners see it as an investment that adds value and aesthetic impact to their property.

Concrete Sealing

Importance of Sealing Concrete: Sealing concrete surfaces can help protect against damage from moisture, staining, and other factors that can cause deterioration over time. It can also enhance the appearance of the surface and make it easier to clean and maintain.

Oct

Excavation

Excavation is typically done with the use of heavy machineries, such as excavators or Skidsteer bobcats, as well as hand tools like shovels and picks. Proper excavation techniques are important for ensuring the stability and longevity of the finished concrete structure, as well as minimizing the risk of accidents or damage to surrounding structures.

Subgrade preparation

The subgrade is the foundation layer, made up of compacted soil, crusher dust or road base aggregate. Its quality directly affects the overall performance of the concrete structure, as well as its longevity and durability. Evaluating the subgrade's properties, such as its strength, stiffness, and moisture content is crucial before constructing a pavement on top of it. Proper preparation and improvement of the subgrade can prevent concrete distress, such as rutting and cracking, which can lead to expensive maintenance and repairs. In summary, the subgrade plays a critical role in ensuring the long-term performance of a concrete system, and it is essential to give it due consideration during construction.
