Bluestone pavers are a premier choice for homeowners, landscapers, and designers seeking to combine natural beauty with exceptional durability. This distinctive natural stone, renowned for its stunning blue-grey hues and unique character, has been a cornerstone of architectural and landscaping projects for centuries. From the cobblestone streets of historic cities to the sleek, modern patios of contemporary homes, bluestone offers a versatility that is hard to match. Its innate strength allows it to withstand heavy foot traffic and harsh weather conditions, while its aesthetic appeal provides an instant upgrade to any property. Choosing bluestone is an investment in a surface that not only looks magnificent on day one but will continue to age gracefully, developing a rich patina that tells a story over time.
This article guide will explore everything you need to know about bluestone pavers, from their geological origins to installation, maintenance, and the final design choices that will make your space truly unique.
What Exactly Are Bluestone Pavers?
Bluestone is a cultural and commercial name for a type of sandstone or basalt that is notable for its striking blue-grey colouration. In Australia, the term typically refers to a dense, hard basalt that is quarried and then cut into pavers, tiles, and other landscaping products. This stone is formed from the rapid cooling of volcanic lava, a process that gives it its incredible density and strength. The signature blue colour, often interspersed with subtle hints of rust, brown, and lilac, comes from the mineral content within the stone, particularly iron and carbon compounds. Each bluestone paver is entirely unique, featuring its own variations in colour and texture, which means your paved area will be a one-of-a-kind masterpiece. Unlike manufactured concrete pavers, bluestone offers an organic, natural look that blends seamlessly with the environment.
It is this combination of raw, earthy beauty and formidable physical properties that has cemented bluestone’s status as a premium paving material for both residential and commercial applications across Australia and the world.
Why Choose Bluestone for Your Project? Unmatched Benefits
The decision to use bluestone is supported by a long list of compelling advantages that make it stand out from other paving options. Its primary benefit is its phenomenal durability and longevity. As a volcanic rock, bluestone is incredibly hard-wearing, resistant to cracking, and can handle immense pressure, making it ideal for driveways as well as pedestrian areas. Furthermore, it is naturally slip-resistant, especially in its honed or textured finishes, providing a safe surface around pools, patios, and pathways, even when wet. From an aesthetic standpoint, bluestone is incredibly versatile. Its neutral, cool-toned palette complements a vast range of architectural styles, from traditional and rustic to minimalist and modern. It also pairs beautifully with other materials like timber, white rendered walls, and lush green plants.
Bluestone is also valued for its thermal properties; it remains cool underfoot compared to materials like brick or concrete, which is a significant advantage in the Australian climate. Finally, as a natural product, it is an environmentally friendly choice, requiring minimal processing and possessing a timeless appeal that never goes out of fashion, thereby adding significant value to your property.
A Step-by-Step Guide to Installing Bluestone Pavers
Proper installation is the critical factor that ensures the beauty and longevity of your bluestone paving. The process requires careful planning and execution.
- Planning and Preparation: The first step involves meticulous planning. Measure the area to be paved to calculate the number of pavers required, always adding an extra 10% for cuts and waste. Decide on the pattern, such as a simple stack bond or a more complex herringbone design. Next, prepare the base. This is the most crucial part of the entire process. The existing soil must be excavated to a depth of at least 100-150mm below the desired finished level. The subsoil is then compacted using a plate compactor to create a stable, unyielding foundation.
- Laying the Base and Sand: Once the sub-base is compacted, a layer of road base or crusher dust (approximately 75-100mm thick) is spread over the area. This layer must be levelled and compacted with extreme care, as it provides the ultimate support for your pavers. Any dips or bumps in this base will telegraph through to the final surface. After compacting the road base, a bedding layer of coarse, sharp sand is spread to a depth of about 30-40mm. This sand layer is screeded perfectly level using a straight piece of timber or aluminium, creating a smooth, even surface on which to lay the pavers.
- Laying and Cutting the Pavers: Begin laying your bluestone pavers from a fixed corner point, such as a house wall or a straight edge. Work your way outwards, placing each paver carefully onto the sand bed. Use spacers to maintain consistent joints between the pavers. As you reach the edges of your project area, you will need to cut pavers to fit. This is best done with a diamond-blade wet saw, which ensures a clean, precise cut while keeping dust to a minimum. Always wear appropriate safety gear when cutting stone.
- Compacting and Sealing: After all the full and cut pavers are in place, spread a fine, dry jointing sand over the entire surface. Use a soft broom to sweep the sand into the gaps between all the pavers. The final step is to run the plate compactor over the entire paved area, which vibrates the pavers down into the sand bed and locks them together while simultaneously filling the joints completely. For added protection against staining and to enhance the colour of the stone, applying a penetrating sealer is highly recommended once the surface is completely clean and dry.
Caring for Your Bluestone Surfaces: Maintenance Made Simple
While bluestone is a low-maintenance material, a small amount of care will keep it looking pristine for decades. The primary maintenance task is regular cleaning. Simply sweeping away dirt and debris with a stiff broom and occasionally rinsing with a garden hose is usually sufficient for day-to-day upkeep. For a deeper clean, especially if dealing with moss or mildew, use a mild detergent mixed with warm water and scrub with a stiff brush. It is crucial to avoid harsh acidic or alkaline cleaners, such as vinegar or bleach, as these can etch the stone’s surface and permanently damage its finish. For oil or grease spills, act quickly by absorbing the excess and using a dedicated stone poultice or a paste made from baking soda and water to draw the stain out. Sealing your bluestone pavers is not always mandatory, but it is highly advisable.
A quality impregnating sealer will penetrate the stone and provide an invisible barrier against water, oil, and dirt penetration, making future cleaning much easier and helping to preserve the stone’s natural colour. Reapplying sealer every two to three years is typically recommended to maintain optimal protection.
Inspiring Design Ideas for Bluestone Pavers
The applications for bluestone pavers are virtually limitless, offering a sophisticated solution for both grand and intimate spaces.

- Durable and Attractive Driveways: For a driveway that combines immense strength with curb appeal, bluestone cobbles or large-format pavers are an excellent choice. They can withstand the weight of vehicles while maintaining their structural integrity and aesthetic value.
- Serene Pool Coping and Decking: The natural slip-resistance and cool-to-the-touch quality of bluestone make it a supremely safe and comfortable choice for pool surrounds. Its colour beautifully contrasts with the blue water of a swimming pool.
- Modern Interior Flooring: Bluestone is not just for outdoors. Using honed and filled bluestone tiles indoors creates a sleek, modern, and incredibly durable floor for living areas, kitchens, and bathrooms, bringing a touch of organic nature inside the home.
