Hello.
According to the architect, a strip foundation should be more cost-effective. We are planning a single-family house with a basement.
In my opinion, however, such a foundation involves considerably more work, whereas a slab foundation without strip footing would just require a few centimeters more concrete... Labor costs are often higher than the raw materials. We don’t have any quotes yet since we are not that far along, but I would still be interested in your experiences.
The energy consultant prefers the slab foundation, as it is easier to insulate and carries less risk of thermal bridges – which makes sense to me.
What are your experiences with this?
Thanks and best regards from Swabia.

It always depends—however, if there is no slope and the soil is not load-bearing, then gravel would only be good for the earthworks contractor.

Ulrich Fuckert19 Aug 2016 07:59The difference actually lies in the structural system. On appropriate soil, strip foundations do not require reinforcement and can transfer the loads directly into the ground. The slab then only needs light structural reinforcement. It is different with a load-bearing slab. Here, the loads must be fully supported by the slab, meaning the slab becomes the load-bearing element and is usually heavily reinforced.

20cm (8 inches) crushed stone under the slab...Hello
I consider the 20 cm (8 inches) as a capillary-breaking layer.
