πŸ’‘ How to Calculate Concrete Wall Volume

Wall volume = length Γ— height Γ— thickness. Standard foundation walls are 8 inches thick for 1-story homes and 10 inches for 2-story. Basement walls are typically 8–10 inches thick and 8 feet tall. Add 5% for waste and form settlement.

Poured concrete walls require steel forms, rebar reinforcement, and proper curing. Walls over 4 feet tall need horizontal and vertical rebar β€” typically #4 bars at 12-inch centers both ways. Plan for inspection before the pour.

A 40 ft foundation wall, 8 ft high, 8 inches thick: 40 Γ— 8 Γ— 0.67 = 213 cu ft = 7.9 cu yd. Order 8.3 cu yd (+5%). At $130/yd, cost β‰ˆ $1,079.
