Calculate Volume of Concrete
🏗️ Calculation of the volume of concrete for the foundation and screed
This calculator helps you determine exactly how many cubic meters of mixture (m³) to order at the factory. An error in calculations is costly: either you overpay for an extra mixer, or there is not enough concrete to complete the monolith, which is critical for strength.
How to choose a calculation type?
- 🧱 Strip foundation: Choose this type if you plan to fill the contour under load-bearing walls. If you have not yet calculated materials for walls, we recommend our building block calculator.
- ⬛ Slab (Screed): Ideal for calculating floors, ceilings or flat foundations. It works according to the formula: Area (m²) × Thickness (m).
- 🏛️ Column / Pile: For round supports and bored piles. You need to know the height and diameter.
Frequently asked questions (FAQ)
🔹 How to convert liters or kilograms to cubes (m³)?
Concrete plants ship products strictly in cubic meters. The weight of 1 cube depends on the brand of concrete (usually 2300–2500 kg). Our volume calculator gives the result immediately in m³, so that it is convenient for you to place an order.
🔹 Is it possible to use a calculator to calculate mortar for masonry?
No, this tool calculates the volume of a monolithic fill. The consumption of mortar for laying bricks or blocks is calculated differently (usually 0.2–0.3 m³ per cube of masonry).
🔹 What is the “compression factor”?
When pouring, concrete is compacted with a vibrator, expelling air. The volume of the mixture decreases. For an accurate order, we recommend multiplying the result by a factor of 1.05 (that is, adding 5%).
