Concrete Base Calculator
Calculate concrete volume, materials needed, and costs for your foundation, slab, or patio project. Get precise measurements for any concrete base.
Step 1: Base Dimensions
Concrete Base Measurements
Accurate dimensions are crucial for calculating the correct amount of concrete. Standard slab thickness is 4-6 inches for patios and 6-8 inches for driveways.

About Concrete Bases
Concrete volume is calculated in cubic yards. One cubic yard covers 81 sq ft at 4″ depth. Always order 5-10% extra to account for spillage and uneven subgrade.

Concrete Mixing Instructions
For manual mixing: One 80-lb bag yields approximately 0.6 cubic feet of concrete. Mix with clean water according to manufacturer instructions. Pour within 30 minutes of mixing.
Cost Breakdown
Concrete Volume Formula
Cubic Yards = (Length × Width × Depth) ÷ 27
Calculate volume in cubic feet first (Length × Width × Depth in feet). Then divide by 27 to convert to cubic yards. Multiply by waste factor (typically 10%) for total yards needed.
