Concrete and Exposed Aggregate Surfaces

At Fluid Limestone in Perth, WA, we specialise in liquid limestone and exposed aggregate surfaces for spaces such as driveways, gardens, backyards, pool surrounds, patios, walkways, and other outdoor areas. Whatever type of exterior renovation project you have in mind, we can help you to achieve outstanding results within your specified budget. Although we specialise in exposed aggregate and liquid limestone, we have plenty of experience of working with other concrete surfaces, pavers, and custom inlays so whatever your requirements, we are sure that we can meet them.

Why use Exposed Aggregate in Perth ?

Exposed aggregate has all the benefits of plain concrete surfaces, with the following additional advantages:

  • Enhanced Durability – The top layer of aggregate takes most of the pressure from vehicles or foot traffic, protecting the concrete underneath. This ensures that cracks and splits are a rare occurrence with such surfaces.

  • Unique Appearance – The choice of aggregates and the custom nature of the mixing and application processes means that every surface is unique. If a bland, grey concrete surface does not appeal to you, an exposed aggregate surface is the perfect solution.

  • Increased Traction – The rough nature of the surface provides extra traction, which is particularly useful in wet conditions.

If you are interested in premium finishes, exposed aggregate surfaces can be completed with a number of attractively coloured materials for visually stunning results.

How We Approach Concrete and Exposed Aggregate Projects

All of the materials and labour practices that we use meet or exceed current Australian Standards so quality and safety are not issues you will ever have to worry about when we are working in and around your home.

The way that we approach the creation of a new exposed aggregate surface depends on the area in which we are working. For new surfaces that will replace a completely unprepared area such as bare earth, we will normally create a foundation of stakes and planks, over which a concrete mix is poured. For more even surfaces, such as existing walkways and driveways, we will start by moving sand and levelling the ground, before pouring the initial concrete mix.

Whichever approach is called for, the next stage involves the application of a surface retarder that will keep the uppermost layer of concrete wet whilst the lower layers dry completely.


The final stage involves the application of the exposed aggregate onto the still wet concrete surface. This final layer of gravel and stones is literally thrown across the wet concrete, producing a unique finish that can be customised to suit your personal preferences and needs. After an hour or two, when the uppermost surface is partially set, we use a roller and push broom to ensure that an even distribution is achieved.

Low Maintenance Surfaces

The concrete pavers and exposed aggregate surfaces that we create are an extremely durable, low maintenance solution for areas such as pool surrounds, backyard patios and outdoor play areas. They are very easy to to keep clean – a quick spray with the garden hose is all that is normally required, and they do not attract insects or dust. Their durable nature means that they are able to provide many years of service without any noticeable degradation, even in high traffic areas.

Cool and Attractive

Concrete and exposed aggregate stays much cooler than most materials in hot weather conditions and because we can customise the mix, and the type of stones used, we can create surfaces that blend in perfectly with the existing exterior of your property or the flowers you have chosen to plant in your garden. In short, exposed aggregate provides all of the longevity and practicality benefits of concrete with none of the aesthetic drawbacks.

Because you can choose from a wide variety of concrete mixes and different types of aggregate, your new surface can be tailored to meet your budgetary needs as well as your personal preferences and practical requirements.
