Gravel Calculator for Concrete
Calculate the exact amount of gravel needed for concrete projects including foundations, slabs, and footings. Determine gravel volume based on area dimensions, depth, and project type.
Step 1: Project Dimensions
Understanding Gravel Requirements
Gravel provides a stable base for concrete, prevents soil movement, and aids drainage. Typical depth is 4-6 inches for most concrete projects.
Step 2: Gravel Specifications
About Gravel Calculations
Gravel is measured in cubic yards or tons. A cubic yard of gravel typically weighs 1.25-1.5 tons. Always account for compaction (10-15%) and waste (5-10%) in your calculations.

Volume Breakdown
Gravel Calculation Formula
Volume (yd³) = (Length × Width × (Depth/12)) / 27 × Compaction × Waste
Length and width in feet, depth in inches. Multiply by 27 to convert to cubic yards. Adjust for compaction and waste factors.
