MEASURE ONCE. PLAN YOUR PURCHASE.

Concrete Wall calculator.

Sum wall segments, deduct openings and remove explicitly duplicated intersection volume.

CONCRETE

Your inputs

Use measurements from your plan and properties from your chosen product. Any prefilled values are illustrative.

Intersection volume counted twice

yd³

Waste allowance

Shortcuts only; choose your own allowance above.

Where to get this value

Enter your own allowance. Presets are input shortcuts, not a construction recommendation.

Wall segment 1

Segment length

Where to get this value

Measure this dimension in your plan or on site and use the displayed unit. For irregular shapes, divide the geometry into the supported sections.

Height

Where to get this value

Measure this dimension in your plan or on site and use the displayed unit. For irregular shapes, divide the geometry into the supported sections.

Specified thickness

Where to get this value

Measure this dimension in your plan or on site and use the displayed unit. For irregular shapes, divide the geometry into the supported sections.

Opening area

ft²

Where to get this value

Measure only the area, length or quantity to deduct, in the unit shown. Keep this consistent with the surface being calculated.

BEHIND THE NUMBERS

How this calculation works.

Opening deductions use the thickness of their own segment. Intersection deductions must be calculated from your actual joined geometry; the tool does not invent a corner detail.

V = Σ((L × H − openings) × thickness) − duplicate intersectionsCalculated with normalised units

A worked example

Illustrative inputs only. Product properties and design dimensions are not recommendations for your project.

Intersection volume counted twice: 0.1 m³
Waste allowance: 10 %
Segment length: 4 m
Height: 2 m
Specified thickness: 200 mm
Opening area: 1 m²

Concrete to order: 1.43 m³

Before you purchase

Use dimensions from your plan and properties from your chosen product. Any design spacing, section or fixing pattern must already be specified.
