Keen on an exposed aggregate finish but unsure how to make it happen?

We can help.

We’ve helped hundreds of clients throughout Melbourne enjoy vibrant, versatile and durable exposed aggregate surfaces. Now, we’re breaking down the step-by-step process for you.

An exposed aggregate driveway can blend seamlessly with Melbourne’s diverse architectural styles. It can also serve as an impromptu cricket pitch when the car isn’t in the driveway (just be wary of potential spin from the exposed surface).

So whether your home boasts classic charm or contemporary chic, here’s how you create a stunning driveway for your Melbourne home.

Before you start any construction project, it’s essential to plan and design your driveway. 

Consider factors such as the size of your driveway, the desired shape, and any specific patterns or colours you want to incorporate. You should also obtain any necessary permits or approvals from your local authorities.

Take inspiration from the surrounding landscape and the architectural style of your home. Melbourne offers a diverse range of design possibilities, from classic to modern. A well-thought-out design will ensure that your driveway complements the overall look of your property.

Exposed aggregate driveways get their name from the decorative aggregates or stones that are “exposed” on the surface. Melbourne offers a variety of options when it comes to aggregates. Common choices include:

• Crushed granite
• Quartz
• Limestone
• Recycled glass

Consider the colour and size of the aggregates to create the desired aesthetic effect.

Prepare the area for your driveway by excavating the existing surface to the required depth. The depth will depend on the type of soil and the expected load on the driveway.

Generally, a depth of 100-150mm is suitable. Ensure proper drainage by sloping the driveway away from your home to prevent water buildup.

After excavation, it’s essential to create a stable base for your driveway. This usually involves adding a layer of crushed rock or gravel, followed by compaction to ensure a firm and level surface.

Next, create formwork along the edges of your driveway to define its shape. Reinforce the concrete with steel mesh or rebar to enhance its strength and durability. Proper reinforcement is crucial to prevent cracking and ensure the longevity of your driveway.

Now, it’s time to pour the concrete. Mix the concrete according to the manufacturer’s instructions, and make sure it’s of the right consistency. Pour it evenly over the prepared base and spread it using a screed board. Work quickly to avoid any inconsistencies in the surface.

While the concrete is still wet, sprinkle the chosen aggregates evenly across the surface. Use a float or a trowel to press the aggregates into the concrete gently. Be careful not to push them too deep, as they should be partially exposed.

Once the aggregates are in place, use a broom or a brush to lightly sweep the surface to remove any excess materials and create a textured finish. Allow the concrete to cure for at least 48 hours before walking or driving on it. During this time, keep the surface moist to prevent cracking.

To protect your driveway from stains and deterioration, consider applying a sealer. Sealers not only enhance the appearance but also extend the lifespan of your driveway. Reapply the sealer every few years to maintain its effectiveness.

Regular maintenance involves cleaning the surface with a mild detergent and a soft brush to remove dirt and debris. Avoid using harsh chemicals or high-pressure washing, as these can damage the exposed aggregate.

The aggregates also provide excellent traction, making your driveway safe even in wet conditions.
• Low Maintenance: One of the key advantages is their low maintenance requirements. With periodic sealing and routine cleaning, your driveway can maintain its beauty and functionality for many years. Unlike traditional concrete driveways, which may require frequent resurfacing or repairs, they are a cost-effective choice in the long run.

Recycled glass or crushed recycled concrete can be used as aggregates, reducing the environmental impact of your project.

Creating an exposed aggregate driveway can add both beauty and functionality to your home.

With careful planning, the right choice of aggregates, and proper construction techniques, you can achieve a stunning and long-lasting driveway that will enhance your property’s curb appeal for years to come.
