Recommended: 5-10% for compaction and spillage

Weight = Volume × Density
Important Note
Results are estimates. Actual gravel requirements may vary due to compaction, site conditions, and settling. Always order 5-10% extra to account for waste and ensure complete coverage.
Gravel is a loose aggregation of small rock fragments that has been naturally or mechanically produced. It is one of the most commonly used materials in construction and landscaping projects due to its versatility, durability, and relatively low cost. Gravel comes in various sizes, colors, and types, each suited for different applications.
Common uses of gravel include driveways, walkways, drainage systems, landscaping beds, and as a base material for concrete and asphalt. The type of gravel you choose depends on your specific project requirements, including load-bearing needs, drainage requirements, and aesthetic preferences.
Pea Gravel
Small, rounded stones ideal for walkways, patios, and decorative landscaping. Easy to walk on and provides excellent drainage.
Crushed Stone
Angular pieces that compact well, making them ideal for driveways, road base, and construction projects requiring stability.
River Rock
Smooth, rounded stones in various colors. Popular for decorative landscaping, water features, and dry creek beds.
Decomposed Granite
Granite that has weathered into small particles. Creates a natural-looking surface for paths and patios.
- Account for compaction: Gravel can compact by 10-20% after installation, so consider ordering extra material.
- Consider the base: If installing over soft soil, you may need a deeper layer or a fabric barrier.
- Check delivery options: Gravel is typically sold by the cubic yard or ton. Know your local supplier's pricing method.
- Plan for edging: Edge restraints help keep gravel in place and maintain clean borders.
- Factor in irregular shapes: For non-rectangular areas, divide into smaller sections and calculate each separately.
