The Benefits of Open Graded Aggregates in Hybrid and Fully Permeable Paver and Natural Stone Installation


When it comes to modern landscaping and hardscaping, the emphasis is increasingly on sustainability and functionality. One of the innovative approaches gaining popularity is the use of open graded aggregates for hybrid and fully permeable paver and natural stone installations. This method not only aligns with eco-friendly practices but also offers a range of practical benefits. In this blog post, we'll explore the key advantages of using open graded aggregates and why they are becoming a preferred choice for many landscape projects, especially for homeowners in Barrie, Ontario, looking to enhance their properties.


Understanding Open Graded Aggregates

Open graded aggregates are a type of crushed stone that has been screened to remove most of the fines, resulting in a material with a high void content. This means the aggregate particles are of uniform size and do not pack together tightly, allowing water to pass through easily. The two most common types of open graded aggregates used in permeable installations are:

  1. No. 57 Stone: A versatile aggregate often used in base layers.
  2. No. 8 Stone: Typically used for bedding layers.


Key Benefits


1. Enhanced Drainage

One of the primary benefits of using open graded aggregates is their excellent drainage capabilities. The high void content allows water to flow through the aggregate and into the ground below, reducing surface runoff. This is particularly beneficial in areas prone to heavy rainfall, as it helps prevent flooding and erosion. For hybrid and fully permeable paver installations, this means a more effective stormwater management system, which is crucial for maintaining the integrity of the landscape.


2. Reduced Risk of Flooding

By promoting rapid water infiltration, open graded aggregates significantly lower the risk of flooding. Traditional impermeable surfaces like concrete or asphalt can lead to water pooling and overflow during heavy rains. In contrast, permeable installations absorb and disperse water, reducing the strain on stormwater systems and minimizing the risk of urban flooding.


3. Sustainability

Using open graded aggregates supports sustainable construction practices. By allowing water to percolate through the surface, these aggregates help recharge groundwater supplies. Additionally, they reduce the need for extensive stormwater management infrastructure, which can be both costly and environmentally damaging.


4. Durability and Stability

Despite their permeability, open graded aggregates provide a stable and durable base for pavers and natural stones. The uniform size of the aggregate particles ensures a strong interlock, distributing loads effectively and preventing settling or shifting. This stability is essential for maintaining the long-term performance and appearance of the installation.


5. Maintenance Benefits

Permeable paver systems using open graded aggregates are generally easier to maintain. The free-draining nature of the aggregate prevents water from pooling on the surface, reducing the risk of weed growth and the formation of ice in colder climates. This leads to a cleaner, safer, and more visually appealing landscape.


6. Environmental Impact

By using open graded aggregates, you're contributing to a more environmentally friendly landscape. These materials reduce the urban heat island effect, lower surface temperatures, and support natural water cycles. Furthermore, they often involve less excavation and disturbance to the site compared to traditional impermeable surfaces.


Applications in Landscaping

Open graded aggregates are versatile and can be used in a variety of landscaping applications, including:

  • Driveways: Providing a durable and permeable surface that can withstand vehicular traffic.
  • Patios and Walkways: Enhancing aesthetics while ensuring proper drainage.
  • Parking Lots: Reducing runoff and minimizing the need for extensive stormwater management systems.
  • Green Spaces: Supporting sustainable urban development by allowing natural water infiltration.
