ᐅ Heat Pump Foundation Too Close to Garage: Repair or New Construction?

Hello everyone,
Our site manager knowingly allowed the foundation for the external unit of the air source heat pump to be poured with only an 11 cm (4.3 inches) gap from the future garage wall. The air source heat pump’s manual states that there should be at least 20 cm (7.9 inches) clearance.
Now the plumbing specialist has already noticed that it is very close to the garage foundation and has positioned the external unit as far towards the end of the heat pump foundation as possible, to leave as much space as possible. (I assume he didn’t know that the garage extends 30 cm (11.8 inches) beyond the garage foundation on each side.) However, one corner of the heat pump foundation broke off during this process.
In any case, the site manager believes he can repair the break and simply extend the heat pump foundation by 20 cm (7.9 inches), thus achieving just over the required minimum clearance.
Is it possible to repair the break without any issues and extend the heat pump foundation, or is this a substandard, cheap fix? I definitely do not want the foundation to crumble during the next frost. Should I insist on a new foundation?
Thanks for your help.
Best regards,
Snowside

Is that really correct? The corner seems to be hanging in the air...

Is that really correct? The corner seems to be hanging in mid-air...I believe that is correct. All the walls are resting on the foundation, and then the thermal insulation was glued and screwed on. That’s why it looks like the corner is floating. The area around it will be filled with soil later.
markus270325 Jun 2018 18:23Okay, then I misunderstood. I thought the wall was hanging in mid-air there. With the external thermal insulation composite system (ETICS), it’s not as problematic.
