ᐅ Gap in the foundation—does anyone have experience with this issue or any information?

Hello everyone,

We have now been living in our small solid-built house for 1.5 years.
I am currently working on the landscaping step by step, and I noticed that at the back of the house there are gaps forming at several spots (3-4) along the foundation slab.
A brief background: we built without a basement and, following the recommendation from the soil survey, founded the house on a 1.5 m (5 ft) thick gravel base.
Is this normal settling, or would it make sense to consult a specialist?
Anyone with opinions or information?
Attached are some photos; in some places, I can insert a 1 m (3 ft) rod about 20 cm (8 inches) into the gap.
Regards

Earthquake. Volcanic eruption... or simply drought? The volume of the ground has contracted! This has happened everywhere in Germany.

Nordy, don’t always be so cheeky. Te, you do have a warranty. Ask your general contractor.

The dryness and soil shrinkage issue is serious. Really. Soils everywhere have settled by one or two millimeters (around 0.04 to 0.08 inches) as water volume has been lost.

Yes, you can also see that the ground has settled. What worries me more is the gap that is currently forming at the slab. Thanks for your information.

Yes, I do have a warranty. After the GC told me during the construction phase that water behind the vapor barrier is "normal," I expect I’ll be told again that I’m "being too sensitive" 🙂

But you’re right, before I close this up, I’ll give him a call on Monday.
