The Benefits of Using Open Grade Gravel vs. Traditional (Class 5) Gravel

When it comes to selecting gravel for your landscape or hardscape projects, it’s essential to understand the different types of gravel available and how they can impact the functionality, durability, and long-term performance of your outdoor spaces. Two common types are open grade gravel and traditional (Class 5) gravel. While both have their uses, open grade gravel offers distinct advantages over the traditional variety, especially for specific landscaping and drainage needs.

Let’s explore the key differences and benefits of using open grade gravel compared to Class 5 gravel.

1. Superior Drainage with Open Grade Gravel

One of the most significant advantages of open grade gravel is its superior drainage capacity. Unlike Class 5 gravel, which is a mixture of sand, gravel, and fines, open grade gravel is designed with larger stones and fewer fine particles. This structure allows water to pass through more easily, reducing runoff and helping to manage stormwater effectively. Open grade gravel is ideal for areas that need to handle excess moisture, such as driveways, patios, or walkways that see a lot of rain or snow melt.

If you’re designing a drainage system, or creating a permeable surface, open grade gravel ensures that water flows freely through the material, preventing pooling or erosion. It’s especially useful for creating French drains or rain gardens that need excellent water flow.

2. Reduced Compaction and Better Longevity

Class 5 gravel, which includes finer materials, tends to compact over time, creating a solid, almost impervious surface. While this can be desirable for certain applications, it can also lead to drainage problems as water struggles to permeate the compacted material. In contrast, open grade gravel doesn’t compact as much because of its larger stone size and lack of fines. This means it maintains better permeability over time, ensuring that the surface remains functional for longer periods without the need for frequent maintenance.

For areas with heavy traffic or driveways, using open grade gravel can help maintain the surface's integrity, minimizing ruts or holes caused by water infiltration. This can save you money and effort in repairs down the road.

3. Enhanced Stability for Heavy Traffic Areas

Open grade gravel's structure of larger, angular stones provides a more stable foundation than traditional Class 5 gravel. This makes it a better choice for areas that will see a lot of weight and movement, such as parking areas, driveways, and walkways. The larger stones lock together more securely, reducing shifting and erosion. Class 5 gravel can sometimes shift under pressure or during wet conditions, leading to uneven surfaces, which can be frustrating and require more frequent adjustments.

4. Better for Long-Term Permeable Pavement

For homeowners looking to create permeable pavements or eco-friendly landscapes, open grade gravel is the ideal choice. It meets the standards for permeable paving systems, which are becoming increasingly important in urban areas where stormwater management is a concern. Open grade gravel allows water to infiltrate the ground naturally, replenishing groundwater and reducing the strain on municipal stormwater systems.

In contrast, traditional gravel can often lead to runoff and water pooling, which contributes to erosion and pollution. Open grade gravel provides a sustainable, environmentally friendly solution that aligns with modern landscaping trends focused on sustainability and water conservation.

5. Low Maintenance and Less Weed Growth

Open grade gravel can also be easier to maintain than traditional gravel. Because it is less compacted, there is less soil contact and less opportunity for weed seeds to take root. In contrast, the finer particles in Class 5 gravel can create a more fertile environment for weeds to grow. Additionally, open grade gravel’s structure means that debris and organic matter tend to wash away more easily, reducing the buildup of materials that can encourage weed growth.

While you’ll still need to perform routine maintenance, such as raking or replenishing the surface, open grade gravel requires less effort to keep weeds at bay and maintain its aesthetic appeal.

6. Aesthetic Appeal with Open Grade Gravel

Open grade gravel tends to have a cleaner, more uniform appearance because of the larger, more uniform stone sizes. This can give your landscape a more polished, modern look. It’s particularly appealing for decorative driveways, garden paths, or patios, where visual appeal is a priority. In comparison, Class 5 gravel’s mix of different sizes and fines can appear uneven and less visually appealing.

If you're aiming for a contemporary or sleek design, using open grade gravel will help create a cleaner, more refined surface that complements modern landscaping features.

Which Gravel Should You Choose?

When deciding between open grade gravel and traditional Class 5 gravel, it comes down to the specific needs of your project:

• If drainage is a priority, such as in driveways, patios, or areas prone to water pooling, open grade gravel is the better choice.

• If you need a more compacted surface, like for heavy traffic areas or stable driveways, Class 5 gravel may be a good option.

• For eco-friendly projects, permeable pavements, or areas requiring low maintenance, open grade gravel shines.
