What is Gravel and Its Types

Gravel is made up of loose rock fragments and comes in a variety of types, each suited for different uses in landscaping and construction.

Here are a few common types of gravel and rock:

1. Crushed Stone – Sharp and angular; perfect for driveways, base layers, and drainage.
2. Pea Gravel – Smooth and rounded; great for garden paths, patios, and decorative areas.
3. Decomposed Granite (DG) – Fine gravel that compacts well; used in paths and modern landscapes.
4. River Rock – Larger, rounded stones are often used in beds, water features, or for erosion control.
5. Base Gravel – Coarse and compactable; used under patios, pavers, and concrete foundations.
