Concrete Block Fill Calculator
Calculate how much concrete you need to fill concrete blocks. Estimate materials and costs for block wall projects.
Step 1: Block Details
Understanding Block Fill
Standard concrete blocks typically have two or three cores that need filling. The fill percentage accounts for the empty space within each block that requires concrete.

About Concrete Calculation
Concrete is typically measured in cubic yards or cubic meters. One cubic yard covers approximately 40 square feet at 8 inches thick. Always add a waste factor for spillage and over-excavation.

Volume Breakdown Analysis
Concrete Calculation Formula
Volume = (Blocks × Block Volume × Fill %) × (1 + Waste %)
The total concrete volume is calculated by multiplying the number of blocks by the volume of each block, adjusting for fill percentage, then adding extra for waste. Convert to cubic yards by dividing by 46656 (36×36×36 inches).
