Build probes for geothermal energy - yes or no?

Hello friends, we have a little problem. When we started building back then, we were still very inexperienced and naive. The drilling crew was the very first trade that came to our site and drilled the holes for the probes of the ground source heat pump. They were quite a bungler and rough character, which we didn’t realize at the time, especially since he was only commissioned by the general contractor. In short, the guy didn’t follow the plans but drilled wildly somewhere. This was also because instead of 3 holes, he had to make 6. Now the said holes are unfortunately only about 2.5 meters away from the house and, of course, on the terrace side. We have been planning our terrace for ages, but it keeps failing on the question of whether we can massively build over these things now or not? We have to overcome about 40 cm in height to the terrace door. I would like a small strip foundation with gravel inside and slabs on top. My husband prefers wooden planks on stilts. Basically, everyone would agree to anything as long as these stupid probes don’t get damaged. If we use vibrating plates on them, will they be ruined? Should we dig them out with a spade to see exactly where they are? What would you do?

what kind of probes? Geothermal energy? What exactly are those?

I personally (will also use geothermal energy) would build over it conditionally, so that you can still access it afterwards. You should also know exactly where they are located. I documented everything with pictures and a plan with measurements, so that I can find them again without much effort. I would also have serious concerns about the vibrating plate. Unfortunately, my statement is only based on a gut feeling ✌️

Yes, we feel the same way. We also have photos. Unfortunately, the drill covered the soil over the pipes faster than we could measure everything exactly back then. There were only small flags at the spots, but at least something. It’s no use. I will dig them up this spring to see exactly where they run.

Deep drilling? You can build over it, the heat comes from deep down. Usually, you don't need to touch it anymore.

I would be cautious with such generalizations. Although the heat comes from the ground, there are distributors that one might eventually need to access. The pipes should, of course, be properly laid in sand; then even a vibrating plate won't cause any damage. Those who do it correctly install a shaft with a shaft cover on top, so you can always access it again if one of the probes has problems and needs to be shut off.
