This online calculator will help you determine the required amount of materials for a cement-sand floor screed. Its main purpose is to simplify the calculation process, allowing you to determine how many cubic meters of floor screed are needed, as well as the material consumption per square meter. The calculator takes into account all key parameters, such as floor area and the required screed thickness, to precisely calculate the amount of cement, sand, and other components.

Calculator features:

  • Calculation of floor area for screeding
  • Selecting the screed thickness (typically from 20 to 100 mm)
  • Choosing the concrete mix grade for the required strength
  • Option to include reinforcement mesh calculation (you can calculate the mesh weight here)

To begin the calculation, you need to enter the room’s length and width, select the screed thickness, and specify the concrete mix grade. Once the calculation is completed, the calculator will provide the exact amount of cement, sand, and water required for the floor screed. This helps you prepare all the necessary materials in advance and avoid excess usage.

Additional features:

  • Automatic generation of results in a table format
  • Consideration of component ratios for various concrete grades

For example, for concrete grade C12/15, the cement-to-sand ratio is 1:3, for C16/20 – 1:2.8, and for C20/25 – 1:2.4. Using this calculator allows you to quickly and accurately calculate the floor screed and determine the required amount of materials for your project.
