An exposed aggregate driveway features a special finish where the surface of the concrete is treated to reveal the aggregates, or stones, that are embedded in the concrete mix. These aggregates could be a variety of materials such as crushed stone, gravel, or pebbles. The exposed aggregates give the driveway a textured and decorative appearance, offering a non-slip surface that’s both durable and visually appealing.

This type of concrete finish can be customized with different color schemes, textures, and aggregate combinations to suit your home’s style and your personal preferences.

How is an Exposed Aggregate Driveway Made?

The process of creating an exposed aggregate driveway involves mixing concrete with aggregates. The concrete is poured as a traditional driveway, but the surface is treated to expose the aggregates. Here’s a brief overview of the process:

  1. Preparation: The area for the driveway is measured and prepped, with any existing surface being removed. A base layer of gravel is often used to ensure proper drainage.
  2. Pouring the Concrete: The concrete is mixed and poured into the designated area. This is the same process as pouring a regular driveway, but the aggregate mix is carefully added to the concrete for the desired effect.
  3. Exposing the Aggregate: Once the concrete has been poured, the surface is treated to expose the aggregates. This can be done by either using a chemical retardant or washing the surface after a specific curing time.
  4. Finishing: After the aggregates are exposed, the surface is smoothed and sealed to protect the driveway from the elements and ensure long-lasting durability.

Benefits of Exposed Aggregate Driveways

1. Durability

Exposed aggregate driveways are incredibly strong and durable, making them ideal for heavy traffic. The exposed aggregates increase the strength of the concrete, which is important for driveways that experience constant wear and tear.

2. Low Maintenance

Exposed aggregate driveways require very little maintenance. Regular cleaning and occasional resealing are typically all that’s needed to keep the driveway looking new. The textured surface also helps prevent the accumulation of dirt, making it easier to clean than smooth concrete alternatives.

3. Non-Slip Surface

The textured surface of exposed aggregate concrete offers a natural non-slip surface, which is especially beneficial for homes in areas with wet weather. It reduces the risk of accidents, particularly in the rainy Melbourne climate.

4. Aesthetic Appeal

Exposed aggregate driveways are highly customizable. With a range of color options, aggregate types, and surface finishes, you can create a driveway that complements the overall look of your home. Whether you prefer a natural stone appearance or a more modern, polished look, exposed aggregate can provide a unique and stylish finish.

5. Increased Property Value

The aesthetic appeal and durability of exposed aggregate driveways can increase the curb appeal of your property, which can lead to a higher resale value. Homebuyers often appreciate the low-maintenance, attractive features of exposed aggregate driveways.

Exposed Aggregate Concrete Cost

One of the primary considerations when installing an exposed aggregate driveway is the cost. The price of an exposed aggregate driveway can vary based on factors such as the size of the area, the complexity of the design, and the quality of the materials used.

Cost Factors for Exposed Aggregate Driveways

  1. Size of the Driveway: The larger the driveway, the higher the cost. The price is typically calculated per square meter, with the cost increasing for larger areas.
  2. Type of Aggregate: The type of aggregate you choose can significantly impact the cost. For example, premium or exotic aggregates such as granite or marble can be more expensive than common materials like pebbles or gravel.
  3. Complexity of Design: If you want intricate designs or custom color mixes, the cost will be higher. Simple exposed aggregate finishes are generally more affordable than custom-designed ones.
  4. Preparation and Site Conditions: If the ground needs to be leveled or excavated before pouring the concrete, this will add to the cost. The condition of the site will determine how much preparation is required.

Average Cost of Exposed Aggregate Driveways in Melbourne

The cost of an exposed aggregate driveway in Melbourne can vary widely depending on the factors mentioned above. On average, the cost can range from $80 to $150 per square meter. This cost typically includes the material, labor, and necessary equipment for installation. However, more complex designs or higher-end aggregates can push the price higher.
