How to Calculate Concrete Blocks
Formula
Standard 8×8×16 concrete blocks (CMUs) cover 1.125 blocks per square foot of wall area. A 5% waste factor accounts for breakage.
Block walls require mortar, rebar reinforcement, and sometimes grout fill in the cores for structural strength.
Common use cases:
- Retaining wall construction
- Foundation walls
- Garden and privacy walls
