Estimate concrete for poured foundation and basement walls.

Educational US estimate only. Not engineering, structural, code, or professional construction advice. Mix designs, codes, and local conditions vary — verify with licensed professionals and your building department.

Estimator methodology

BuildToolsHub takeoffs separate net measured quantities from ordered quantities. Ordered qty = net × condition-based waste, then rounded for plant or package sizes (e.g. ready-mix to the nearest 0.5 yd³).

  • Concrete bags: Quikrete / SAKRETE published yields (80 lb ≈ 0.60 ft³). Ready-mix contingencies follow ASTM C94 purchaser practice.
  • Rebar: CRSI published lb/ft tables; optional lap allowance ≈ 40× bar diameter (confirm with drawings).
  • Roofing: NRCA squares (100 ft²); pitch factor √(1+(rise/12)²); ~3 bundles/square for standard shingles.
  • Aggregates / fill: ASTM C29-style densities; swell/compaction allowances for haul and place volumes.
  • Masonry: BIA / NCMA common unit factors (e.g. ~1.125 CMU/ft² for 8×16 face).

Use the Order tab for a supplier call sheet and the Assumptions panel for the exact factors applied to this run.

Why use Foundation Wall Concrete Calculator

Enter wall length, height, and thickness to estimate cubic yards for poured foundation walls.

Openings, steps, and keyed joints change volume. Subtract large openings when accuracy matters.

How to use

  1. Enter job dimensions. Pick a pour/layout condition to set industry waste %, or choose Custom.
  2. Review Net vs Order on the Summary tab — order the rounded quantity, not net alone.
  3. Open the Order tab for a supplier checklist, then print, export CSV, or share the link.

About Foundation Wall Concrete Calculator

Do I subtract window openings?

For rough takes, often ignored; for ordering, subtract large openings to avoid overage.

What thickness is common?

Depends on design; many residential walls are 8–10 inches. Confirm on drawings.

Include footings?

No. Calculate footings with the footing calculator separately.

Is this professional engineering advice?

No. Educational estimates only. Verify with a licensed professional and local codes.
