If you are planning to build a house with a monolithic concrete slab foundation, our Concrete Slab Foundation Calculator will help you determine all the essential parameters. With its assistance, you can establish the optimal thickness of the concrete slab foundation, compute the reinforcement layout, and select the appropriate rebar dimensions.
To perform the calculation, you will need to know the geometric dimensions of your foundation and the approximate weight of the house. The building weight can be easily determined using our online load collection service for foundations.
Our online calculator enables you to:
- Calculate the reinforcement layout for the monolithic concrete slab by determining the required quantity and diameter of rebar bars;
- Perform a punching shear analysis for the concrete slab foundation to ensure structural safety and load resistance;
- Determine the amount of materials needed for formwork and select the optimal board thickness;
- Estimate the foundation cost for an economic comparison of various construction options.
The following input data and factors are used in the calculations:
- Rebar of class B500B with diameters of 8, 10, 12, and 14 mm;
- Reinforcement meshes with grid spacing of 100×100 mm and 200×200 mm;
- Concrete cover thickness of 50 mm;
- Steel density — 7850 kg/m3;
- Rebar splicing by overlap;
- Rebar weight safety factor — 5%;
- Formwork material volume safety factor — 30%.
Use our online Concrete Slab Foundation Calculator to quickly and accurately determine all the essential parameters for your house foundation. This will help you optimize costs and ensure the reliability of your concrete slab foundation.
