Pro Tips

  • Order 15-20% extra material to account for compaction—crusher run compresses significantly when properly compacted
  • Compact in 2-3 inch lifts using a plate compactor rather than dumping full depth at once for a denser, more stable base
  • Install edge restraints before spreading material to prevent crusher run from migrating into lawn areas
  • Slope your crusher run surface 1-2% away from structures (1/8" to 1/4" per foot) for proper drainage

Common Questions

What is crusher run?

Crushed stone (3/4" and smaller) mixed with stone dust that compacts into a solid base

How much per square foot?

~24 lbs per sq ft at 4" depth, or about 0.012 cubic yards

Does it harden like concrete?

No, but it locks together when compacted into a very stable surface

Better than pea gravel?

Yes for driveways—angular pieces compact solid, unlike round gravel

How the Calculator Works

Our calculator multiplies your length, width, and depth measurements to determine the total cubic yards needed for your project. We then convert to tons using crusher run's average weight of 3,000 pounds per cubic yard (1.5 tons) and automatically add your selected compaction percentage to ensure you have enough material after compaction settles.

Formula

Cubic Yards = Length × Width × (Depth ÷ 12) ÷ 27

Tons = Cubic Yards × 1.5

With Compaction = Base × (1 + Factor%)
