Why expert review matters
Every calculator is reviewed by certified professionals to ensure accuracy.Hawkin's CCP, CEP certification ensures professional-grade precision.
How much crushed concrete do I need?
Multiply L × W × depth (ft), divide by 27 for cubic yards, then multiply by 1.35 for tons.
How deep should the base be?
4-6" for residential driveways, 6-8" for parking lots, 4" for patios and walkways.
Is crushed concrete as good as gravel?
Yes, RCA performs similarly and costs 30-50% less. It's approved for base material in most areas.
Does crushed concrete drain well?
Yes, it drains adequately and actually improves over time as cement particles re-bond.
The calculator multiplies your project's length, width, and desired depth to determine total cubic yards needed. It then converts cubic yards to tons using the density of your selected size grade (crushed concrete weighs approximately 1.25-1.40 tons per cubic yard depending on size). We automatically add your selected overage percentage to account for compaction and settling.
Formula
Cubic Yards = (Length × Width × Depth in ft) ÷ 27
Tons = Cubic Yards × 1.35 × (1 + Waste %)
