The foundation doesn't really care whether it has lateral bearing pressure or not. But the ground beneath the foundation is under vertical pressure from the garage and now finds a lateral escape route. And if the foundation then hangs in the air, the garage tips sideways into the pit.
The building authority will shut down the construction measure immediately. Your neighbor or his service provider must pay for the proofs, not you.
How quickly does something like this usually happen? Of course, it depends on the respective office, but can one still expect action on the same day in such a case if one calls there first thing in the morning? The pool will probably be delivered sometime in the next few days and then you won't see anything anymore. Earth loosely poured into the gap between the pool and the excavation would not restore the bearing pressure, and the pool probably cannot absorb the pressure.
Hello,
It was similar for us: our double garage stands on the boundary. The neighbor built with a basement. The basement wall was also on the boundary with us. I hope you can imagine the problem... A structural engineer calculated underpinning: first a 4m deep hole was dug exactly on the boundary. The garage was practically standing on a cliff. Then, in about eight sections about 1m wide each, the earth beneath our strip foundations was dug out and secured with a concrete wall. Our garage now stands on a subsequently built 4m deep wall...
It was quite delicate. We documented everything. The whole operation was a year ago. Until today everything is fine. No cracks or anything similar.
In our residential area, many dig very close to the boundary – the plots are very small. Every garage stands on the boundary. So far, I have never heard of any problems.
Just ask at the building authority and let us know here. I am very curious myself...
That definitely sounds like someone with the appropriate expertise gave it some thought. Unfortunately, there is no corresponding planning or structural calculation for our neighbors. I will report back when I know more.
