When beginning a new construction, no matter if the house is small or large, there are many decisions that must be made. Including which foundation method is most suitable for the existing area.

It is important to choose at an early stage the foundation method that is most cost-effective and the ability to minimize the risks of frost heave.

It is the most proven basic method for this new construction of single-family houses. Conclusion: The conclusion of the thesis is that many of the representatives which works in the construction area choose concrete slab over other house foundations when there is no requirement for a specific house foundation from the customer
