Hello,

I have a plot of land and want to build a single-family house on it. I had a soil report prepared in advance. It turned out that the soil is not particularly load-bearing (silty, sandy) with a bearing resistance of 100. The geologist recommends a 1.20 m thick soil cushion and suggests having everything else calculated by a structural engineer, as there may be subsequent settlements of 2-4 cm. What will the structural engineer generally recommend to me or what measures can be taken to safely build a house on the soil/foundation cushion?

Thank you very much gerrko

The measures are usually stated in the [Bodengutachten] as foundation recommendations. Our situation is similar. 1.40m in depth had to be removed and replaced with various layers of gravel. Additionally, geogrids and drainage were installed.

, can you say approximately how much the replacement cost? We received our soil report today and it reads quite terribly clay, silt, sand, etc…

Including all work, materials ([Schotter, Geogitter, Drainage]), and removal of excess masses, we are at approximately €15,000.

What is important is what is stated in the paragraph [Der Gründungsenpfehlung]. It depends on how much and in what ratio clay, silt, and sand occur there.
