Gravel is a versatile material widely used in landscaping and construction projects due to its durability, cost-effectiveness, and variety of types. However, choosing the right gravel for your project can be challenging without understanding its applications and specifications. Fehn Companies, a trusted supplier of high-quality gravel and aggregates, offers a diverse range of materials tailored to various needs, from playgrounds and drainage systems to road construction. Here, we guide you through selecting the ideal gravel for your project.

Understanding Different Types of Gravel

Gravel comes in various sizes, textures, and compositions, each suited for specific uses. Here are some common types of gravel and their applications:

1. Pea Gravel (3/8” Washed Rock)

Pea gravel is characterized by its smooth, round texture and small size, typically around 1/4 to 3/8 inches. It is commonly used for:

• Backfilling drain tiles and fuel tanks
• Creating playground surfaces
• Landscaping features, including decorative areas and garden paths

2. 3/4” Washed Rock

This medium-sized gravel is versatile and can serve multiple purposes, such as:

• Retaining wall backfill
• Radon rock installation under basement floors
• Landscaping projects requiring moderate drainage

3. Larger Gravel (1 1/2” Washed Rock)

Larger gravel sizes provide excellent drainage and stability, making them ideal for:

• Pipe bedding materials
• Erosion control along slopes
• Landscaping accents for robust features

4. Crushed Limestone and Granite (3/4” Minus)

These materials are crushed to specific dimensions and are commonly used for:

• Base layers under paved surfaces or retaining walls
• Road base work and parking lots

5. Recycled Aggregates (Recycled Asphalt, Class 5 Recycle)

Eco-friendly and cost-effective, recycled materials are perfect for projects like:

• Driveways and trails
• Parking pads
• Subgrade reinforcement for muddy surfaces

Factors to Consider When Choosing the Right Gravel

Selecting the right gravel depends on your project’s specific requirements. Here are some key factors to evaluate:

1. Purpose of the Project

Determine whether the gravel is needed for decorative, functional, or structural purposes. For example:

• Decorative projects benefit from pea gravel or washed rock for their aesthetic appeal.
• Functional projects like drainage systems require materials with excellent water filtration, such as larger washed rock.
• Structural applications, such as road bases, need durable crushed aggregates.

2. Size and Shape of Gravel

Gravel size affects its performance. Smaller sizes like pea gravel provide a smoother surface, while larger sizes enhance stability and drainage. The shape also matters—rounded gravel is gentler on feet, making it suitable for playgrounds, whereas angular gravel interlocks better, providing a stable base for construction.

3. Drainage Requirements

Projects requiring water runoff management, such as rain gardens or retaining walls, benefit from washed rock or riprap. These materials facilitate proper water flow while preventing erosion.

4. Environmental Impact

Opting for recycled aggregates reduces the environmental footprint of your project. Fehn Companies offers eco-friendly options, including recycled asphalt and Class 5 recycle, ensuring sustainable solutions without compromising quality.

Practical Applications of Gravel

Playgrounds

Pea gravel provides a safe and visually appealing surface for playgrounds. Its smooth texture minimizes injuries, while its durability ensures long-term performance.

Drainage Systems

3/4” washed rock or riprap works excellently in drainage applications. These materials prevent water pooling and protect structures from erosion.

Road Construction

For road bases or driveways, crushed limestone and granite offer stability and resilience under heavy loads. Recycled asphalt is a budget-friendly alternative that maintains structural integrity.
