Hello friends,
we have a small problem.
When we started construction, we were still very inexperienced and naive. The very first trade on site was the drilling crew for the geothermal heat pump boreholes. They did a pretty sloppy job, but we didn’t realize it at the time, especially since they were only hired through the general contractor.
In short, the guy didn’t follow the plans and drilled holes randomly. This was partly because instead of 3 holes, he had to drill 6. Unfortunately, these holes are now only about 2.5m (8 feet) from the house and right on the terrace side. We have been planning our terrace for ages, but keep running into the question of whether we can build over these boreholes or not.
We need to overcome a height difference of about 40cm (16 inches) up to the terrace door. I would prefer a small strip footing with gravel inside and slabs on top. My husband is more in favor of wooden planks on stilts. Basically, everyone would agree on anything as long as those darn boreholes don’t get damaged. If we use a vibrating plate compactor on top, will that ruin them? Should we dig them up with a spade to check exactly where they are? What would you do?

Should we dig them up with a spade to see exactly where they are? What would you do?The probe inside the pipe isn’t the problem (they last forever), but usually, they have a rather short connection cable. These cables connect to wiring/distributors to get into the utility room. You might need to access those.
