Types of 3/4 Gravel
3/4 gravel comes in various types, each suited for specific applications. Understanding these differences is essential for selecting the right material for your project.
Crushed Stone Gravel
Crushed stone gravel is made from larger stones that are mechanically crushed into smaller pieces. This type of gravel is angular in shape, which allows it to lock together tightly, making it ideal for driveways and foundations. The rough texture provides excellent drainage and stability.
Pea Gravel
Pea gravel consists of small, rounded stones, typically measuring around 3/4 inch in diameter. Its smooth surface makes it an attractive option for landscaping projects, walkways, and playgrounds. Pea gravel is also excellent for drainage applications due to its void spaces.
River Rock
River rock is similar to pea gravel but is larger and comes in various colors and shapes. It’s primarily used for decorative landscaping and drainage features. The smooth texture and natural appearance make river rock a popular choice for garden beds and pathways.
Quarry Process Gravel
Quarry process gravel includes a mix of different sizes of gravel and stone dust. This blend compacts well, making it suitable for use as a base material for driveways and under concrete slabs. It provides excellent drainage and stability.
3/4″ Minus Crushed Gravel
This type of gravel includes crushed stone with fines (small particles) that help it compact tightly. It’s often used for creating a stable base for asphalt or concrete surfaces. The ability to compact makes it a preferred choice for many construction projects.
Applications of 3/4 Gravel
3/4 gravel can be applied in various scenarios, offering both functional and aesthetic benefits.
Driveways
Using crushed stone or quarry process gravel for driveways provides a durable surface that can withstand heavy traffic. The angular shapes of crushed stones lock together, reducing movement and ruts.
Landscaping
Pea gravel and river rock are often used in landscaping for pathways, garden beds, and decorative features. Their smooth texture and variety of colors enhance the visual appeal of outdoor spaces.
Drainage Solutions
3/4 gravel is commonly used in drainage systems. Its larger size allows water to flow through easily, preventing pooling and flooding. This drainage capability is crucial in areas with heavy rainfall.
Concrete Base
3/4 minus crushed gravel is ideal for creating a solid base under concrete slabs. The compact nature of this gravel minimizes settling and cracking in the concrete.
Erosion Control
In landscaping, gravel can help control erosion by stabilizing soil and directing water flow. It is often used in conjunction with plants to create a natural barrier against soil loss.
Technical Features of 3/4 Gravel
| Feature | Crushed Stone | Pea Gravel | River Rock | Quarry Process | 3/4″ Minus Crushed |

| Shape | Angular | Rounded | Rounded | Mixed | Angular |
| Size | 3/4 inch | 3/4 inch | Varies | Varies | 3/4 inch |
| Drainage Capability | High | Very High | High | Moderate | High |
| Aesthetic Appeal | Low | High | Very High | Low | Low |

Choosing the Right 3/4 Gravel
When selecting the right type of 3/4 gravel, consider the following factors:
Purpose
Identify the primary application for the gravel. If you’re building a driveway, crushed stone may be the best choice. For landscaping, consider pea gravel or river rock.
Drainage Needs
If drainage is a concern, opt for gravel types with larger void spaces, such as pea gravel or river rock. For compacted bases, 3/4 minus crushed gravel is ideal.
Aesthetic Preferences
For decorative applications, choose gravel that complements the overall design of your landscape. River rock offers a natural look, whereas crushed stone may be more utilitarian.
