Find the Best Crushed Rock Supplier Near You

Crushed rock is smaller particles of massive stones that are broken down by crushing machines. Crushed rock is generally used as an aggregate for construction and landscaping purposes. Crushed rock is made from common types of rocks such as limestone, dolomite, granite and trap rock. In some cases, crushed rock can also be composed of slate, marble, quartzite, sandstone and volcanic cinder.

Crushed rock can be used for a range of purposes including paving blocks and concrete for sidewalks, patios, driveways, homes, paved roads, as well as office buildings. Crushed rock can also be used as a base or sub-base material in mixing cement. Additionally, crushed rock creates tarmac and asphalt when mixed with a binder.

This crushed rock mixture is commonly used as driveway fillers and extenders to keep road construction firm and robust with an ethically pleasing finished product. The Macadam Technique also uses this crushed rock mixture which is designed to keep the structure strong and stable, particularly with the angular shape of the rocks that interlock with each other and close any gaps.

Crushed rock and gravel are two different kinds of aggregate. These aggregates are used for different purposes and provide different benefits to a construction project. It is best to identify the uses of these materials before you start working on your project for a fast and efficient process without having to worry about the project’s longevity.

Crushed Rock Crushed rock is commonly used for projects such as driveway construction and landscaping. Crushed rock is relatively cheap and comes in different sizes and colours, allowing customers to achieve their desired aesthetic. It can be used for railway track ballast beds, drainage systems, filler material, and retaining walls on shorelines and mountain roads.

Gravel One of the main differences between gravel and crushed rock is that gravel is not man-made. Unlike crushed rock that is produced from crushing machines, gravel is naturally formed from large rocks due to erosion. Gravel also has a rounder and smoother shape compared to crushed rock.

The utilisation of gravel can be compared to that of crushed rock. Gravel can also be used for driveway construction and landscaping. In addition, gravel is useful on construction sites with its lighter weight. While gravel tends to be cheaper than crushed rock, it usually does not provide an aesthetic appeal.

On average, gravel is the cheapest type of crushed rock. It costs an average price of $60 to $75 per yard or $1 to $3 per square foot for the material, delivery and spreading. For example, installing a 4 x 20 gravel walkway costs around $250, landscaping a 10 x 20 gravel patio costs around $450, while installing a gravel driveway costs around $600 to $1,800.

Crushed rock serves a variety of construction and landscaping needs, each type offering distinct advantages for specific applications.

• Limestone is ideal for road bases and drainage layers due to its durability and ability to improve soil pH levels, enhancing plant growth in landscaped areas.
• Granite, known for its hardness and beauty, is preferred for decorative features, countertops, and driveways, providing a long-lasting, aesthetically pleasing surface.
• Basalt, with its exceptional strength and weather resistance, is chosen for heavy-duty road bases and high-traffic areas, ensuring longevity under stress.
• Gravel is versatile, perfect for landscaping, pathways, and driveways, offering good drainage and a natural look that complements any outdoor space.
• Recycled Concrete Aggregate (RCA), an eco-friendly option, is used for sub-bases, fill material, and under paving, supporting environmental sustainability while providing a sturdy base.
• Road Base materials, including crushed rocks like limestone and granite, are fundamental for creating stable and durable foundations for roads, paths, and driveways.
• Stone Dust, with its fine particle size, is excellent for creating a stable paver base or filling between paving stones, though it's limited in drainage capabilities.
• Crush and Run, a mixture of crushed stone and stone dust, is a cost-effective and durable option for driveways and base materials, compacting well to create a solid surface.
• Crushed Limestone, similar to limestone but with a smaller, more uniform size, is great for enhancing soil pH, improving drainage, and as a decorative element in landscaping.
• Sand and Aggregate Blends are crucial for concrete mixes and base layers for paving, offering the right balance of strength and flexibility for various construction projects.
• Pea Gravel, with its smooth texture and ability to drain well, is ideal for walkways, garden beds, and as a decorative element around patios and ponds.
• Caliche offers a cost-effective solution for rural roads and driveways, especially in arid regions, hardening over time to create a durable surface.
• Crushed Granite provides unique color options for high-end landscaping and decorative features, delivering durability along with its aesthetic appeal.

Each type of crushed rock has been tailored for specific uses, from enhancing the beauty of outdoor spaces to providing the foundation for roads and buildings, ensuring both functionality and visual appeal.

Selecting the right crushed rock depends on your project's specific needs. For structural projects like foundations or road bases, you'll want a durable rock, like basalt or granite. For aesthetic landscaping, granite or gravel might be more appropriate due to their appearance. Consider factors like drainage, foot traffic and vehicular use when making your choice.

The price of crushed rock varies widely based on the type, location and quantity purchased. On average, prices can range from $20 to $60 per tonne or cubic metre, with granite and basalt generally being more expensive than limestone or recycled concrete. It's always best to request a quote from suppliers for the most accurate pricing.

Yes, crushed rock is a popular choice for driveways due to its durability and aesthetic appeal. Granite and gravel are commonly used for their attractive appearance and ability to withstand heavy traffic. Proper installation and a suitable base layer are crucial for longevity.

The main difference lies in size and surface. Crushed rock is larger and has jagged edges, providing better stability and making it suitable for high-traffic areas and structural applications. Pea gravel is small, rounded, and smooth, ideal for decorative purposes, playgrounds, and gentle on bare feet paths.

To calculate the amount of crushed rock needed, you'll need to determine the project area's square footage (length x width) and desired depth. As a general rule, one ton of rock covers about 80 to 100 square feet at a 2-inch depth. Use an online material calculator for a more precise estimate, or consult with a supplier to ensure you purchase the correct amount.

It depends on the type of crushed rock, where you are in Australia, and how you’re sourcing it (quarry vs landscape supplier). Here’s a breakdown to help you get a ballpark figure:

Typical Crushed Rock Cost per Tonne in Australia

Bottom Line: Crushed rock in Australia typically costs around $20 to $100+ per tonne, depending on the material and source.

The size of crushed rock you need depends on the purpose of your project. Smaller sizes (5–10 mm) are ideal for pathways, decorative finishes, or fine compaction, while medium sizes (10–20 mm) suit driveways, footpaths, and general construction. Larger sizes (20–40 mm) are commonly used for sub-bases, drainage, and heavy-duty load-bearing applications. Choosing the correct size ensures stability, proper compaction, and durability.

Tip: For driveways or sub-bases, combine medium sizes with fines to improve compaction and surface stability.

Crushed rock and gravel are both commonly used for construction and landscaping, but they differ in origin, shape, and performance. Crushed rock is mechanically crushed from larger stones, giving it angular edges that interlock well and compact firmly. Gravel is naturally formed through weathering and erosion, resulting in rounded edges, which makes it less stable under heavy loads but smoother underfoot.

Tip: For load-bearing surfaces like driveways or sub-bases, crushed rock is preferred. Gravel works well for decorative or low-traffic areas.

The quantity of crushed rock depends on the driveway’s area, depth, and type of rock. A typical residential driveway is usually 100–150 mm thick, and you can calculate the required volume using:

Volume (m³) = Area (m²) × Depth (m)

Tip: Always order 5–10% extra to account for compaction, spillage, and uneven surfaces.

Yes, crushed rock is commonly used in drainage applications because its angular particles create gaps that allow water to flow freely while preventing soil from clogging the system. It is often used in French drains, trench drains, and around pipes to manage water flow and reduce erosion.

Tip: For effective drainage, combine crushed rock with geotextile fabric to prevent soil from mixing with the rock and blocking water flow.
