What Is Gravel?

Gravel is a loose aggregation of rock fragments. It is formed through the natural process of weathering and erosion, where larger rocks break down into smaller pieces over time. Gravel can also be produced artificially through crushing larger rocks. The size of gravel particles typically ranges from 2 to 64 millimeters in diameter, making it distinct from smaller particles like sand and larger particles like cobblestones.

Types of Gravel

Gravel comes in various types, each suited for different purposes. Understanding the different types of gravel can help you choose the right one for your specific needs.

Pea Gravel

Pea gravel is a small, smooth, and rounded type of gravel. It is named for its resemblance to peas. Pea gravel is often used in landscaping for pathways, driveways, and decorative purposes. Its smooth texture makes it comfortable to walk on and visually appealing.

Crushed Stone

Crushed stone is produced by mechanically crushing larger rocks into smaller pieces. It is available in various sizes and shapes, making it suitable for a wide range of applications, including construction, drainage, and landscaping. Crushed stone is often used as a base material for roads, driveways, and patios.

River Rock

River rock is a type of gravel that is naturally smoothed by the action of water in rivers and streams. It is available in various sizes and colors, making it a popular choice for landscaping projects. River rock is often used for decorative purposes, such as in garden beds, water features, and dry creek beds.

Bank Gravel

Bank gravel is a type of gravel that is found in natural deposits along riverbanks and in stream beds. It is typically composed of a mix of sand, silt, and small to medium-sized gravel particles. Bank gravel is often used in construction projects, such as for concrete aggregates and drainage systems.

Lava Rock

Lava rock is a type of gravel that is formed from solidified lava. It is lightweight, porous, and has a unique, rugged appearance. Lava rock is often used in landscaping for decorative purposes, such as in garden beds and rock gardens. It is also used in gas grills and fire pits for its ability to retain heat.
