Information on the purpose of the calculator

Online calculator for monolithic concrete slab foundation is designed to calculate the dimensions, formwork, the number and diameter of reinforcement and the volume of concrete required for arranging this type of foundation for houses and other buildings. Before choosing the type of foundation, be sure to consult with experts whether this type is suitable for your conditions.

A slab foundation is a monolithic reinforced concrete foundation laid under the entire building area. It has the lowest ground pressure among other types. It is mainly used for light buildings, since with an increase in the load, the cost of this type of foundation increases significantly. With a small depth, on sufficiently heaving soils, it is possible to evenly raise and lower the slab, depending on the time of year.

Be sure to have good waterproofing on all sides. Insulation can be both sub-foundation and located in the floor screed, and most often extruded polystyrene foam is used for these purposes.

The main advantage of slab foundations is the relatively low cost and ease of construction, since, unlike strip foundations, there is no need to carry out a large amount of excavation. Usually it is enough to dig a pit 30-50 cm deep, at the bottom of which a sand cushion is placed, as well as, if necessary, geotextiles, waterproofing and a layer of insulation.

It is imperative to find out what characteristics the soil under the future foundation has, as this is the main decisive factor in choosing its type, size and other important characteristics.
