Excavating strip foundation on poor soil

What the cell phone corrects so easily
From 2.2-4.0 comes gravel, sandy, weakly silty.

The architect said it would be enough to dig down to 2.2 and then simply set a strip foundation...

A 2m high strip foundation is of course nonsense... Either replace the soil or build a basement. The former will be so expensive that one can seriously consider a basement.

He said that strip foundations can be made up to about 3m. A basement is just such a thing... first of all because of the costs and because of the groundwater which is at 1'.

In any case, it is an expensive piece of land to develop. You said it hasn't been purchased yet. Is it cheap? Then that would somewhat balance things out. Or are there alternatives? Is the soil like this everywhere for you? Karsten

Aha, I've never heard such nonsense before.. I recommend that if you are serious about the property, you have a foundation recommendation created by a soil engineer.

For the region it is not favorable, however there are hardly any alternatives... Price will roughly be around 95€/m^2.
