Main steps of foundation desing1. Design of the layers (decisions: waterproofing level, loadbearing structureof the basement)
2. Determining the width of the foundation strips (total thickness of thesuperstructure + overlappings of the waterproofing + 2*5 cm tolerance)
3. Determining the depth of the foundation strips (loadbearing soil -10 cm, atleast 50 cm, geometry, frost level, neighbouring building, subsoil water)
4. Designing the individual situations (level change/steps of the foundation(max. 30 degree), level next to a neighbouring building)
