Whether you need gravel for a small residential driveway or a large-scale road development, our bulk delivery services provide high-quality, screened material at competitive prices.
3. Pea Gravel
Pea gravel is a versatile, small-sized aggregate commonly used in landscaping, drainage systems, and certain road construction applications. Typically measuring between 3/8″ and 1/2″ in diameter, pea gravel consists of naturally smoothed stones formed through natural weathering or mechanical processing. It is commonly made from materials like limestone, granite, or quartz.
Why Choose Pea Gravel?
- Superior Drainage – Pea gravel’s small, rounded stones create spaces that allow water to drain quickly, preventing puddles and runoff buildup.
- Low-Maintenance & Durable – Its smooth, natural finish makes it an excellent choice for paths, patios, and decorative driveways that require minimal upkeep.
- Ideal for Permeable Surfaces – Used in French drains, garden beds, and erosion control solutions where water management is a concern.
- Aesthetic Appeal – Available in various natural colours, pea gravel enhances outdoor spaces with a polished, decorative look.
While pea gravel is less commonly used as a primary road base, it can be applied as a surface layer for driveways or as a functional drainage material in road construction projects.
Soil Kings offers premium pea gravel in bulk, ensuring you get the exact amount needed for your landscaping or construction project—no unnecessary waste or plastic bags.
4. Recycled Asphalt
Recycled asphalt, also known as asphalt millings, is an eco-friendly, cost-effective alternative to traditional paving materials. This type of road gravel is made by grinding up old asphalt from roads, highways, and parking lots, repurposing it into a durable, reusable material for driveways, road construction, and pathways.
Why Use Recycled Asphalt?
- Sustainable Choice – Repurposes existing asphalt, reducing landfill waste and environmental impact.
- Naturally Binds Together – The fine particles harden and compact over time, forming a stable, long-lasting surface.
- More Affordable than New Asphalt – Provides the same durability at a fraction of the cost, making it ideal for budget-conscious projects.
- Resistant to Weather & Traffic Wear – Holds up against freeze-thaw cycles, heavy vehicle traffic, and erosion.
Recycled asphalt is commonly used for driveways, rural roads, parking areas, and farm lanes, providing a low-maintenance yet sturdy surface.
At Soil Kings, we provide high-quality recycled asphalt in bulk, delivering a durable, cost-efficient option for your road and driveway needs.

Benefits of Using Road Gravel
Road gravel offers a range of significant advantages, particularly for road construction, driveways, and pathways. Its natural properties make it a highly durable, affordable, and low-maintenance material for various applications. Let’s take a closer look at some of the key benefits of using road gravel: durability and longevity, cost-effectiveness, and easy maintenance.
1. Durability and Longevity
One of the most important benefits of using road gravel is its impressive durability and longevity. Gravel, especially when used in road construction, can withstand heavy traffic loads and harsh weather conditions. When properly compacted, gravel forms a solid surface that resists wear and tear over time, making it ideal for roadways, driveways, and pathways.
Gravel’s ability to resist the development of potholes and ruts is one of the key reasons it is used for high-traffic roads. Its natural flexibility allows the material to shift and settle without cracking, unlike asphalt or concrete, which can crack or buckle over time. This makes gravel a practical and long-lasting option for regions that experience fluctuating temperatures, such as freezing and thawing in colder climates.
When gravel is used in road construction, it’s laid in multiple layers, with the coarse gravel placed at the bottom for stability and the finer gravel on top for a smoother finish. This layered structure improves the road’s overall strength, ensuring that it holds up well over the years. Properly compacted gravel roads can last for decades with minimal deterioration.
2. Cost-Effectiveness
Gravel is a cost-effective alternative to more expensive materials like asphalt or concrete. For both road construction and residential applications such as driveways and pathways, gravel offers a budget-friendly solution without compromising on quality or durability.
One of the reasons gravel is so cost-effective is its relatively low material cost. It can be sourced locally, which reduces transportation costs and allows for affordable bulk pricing. The savings are passed directly to the consumer, whether for large-scale road projects or smaller landscaping projects. In addition, gravel is easy to install, which reduces labour costs compared to the more complex installation processes required for asphalt or concrete. For example, while asphalt requires a specific mixture and heating process during installation, gravel can be laid quickly with minimal equipment, speeding up the project timeline and lowering labour expenses.
For areas that experience high traffic volume, gravel’s ability to maintain its quality with minimal upkeep offers a substantial reduction in long-term maintenance costs.
3. Easy Maintenance
Maintaining gravel surfaces is relatively simple compared to other materials like asphalt or concrete. Gravel offers ease of upkeep, helping property owners and municipalities save time and money on repairs and restoration. The natural drainage properties of gravel are also a major benefit for maintenance.
One of the key advantages of gravel is that it doesn’t crack or warp like asphalt or concrete, meaning you don’t have to worry about costly patchwork or resurfacing. Over time, gravel may experience some wear, such as areas becoming uneven or sunken due to erosion or heavy traffic. However, this can be easily corrected through a process called regrading. Regrading involves redistributing the gravel to level out the surface and ensure even coverage, which is a simple and affordable task that can be done periodically to maintain the gravel’s integrity. For residential driveways and pathways, gravel is also easy to replenish if areas start to look worn down.
