ᐅ Is the borehole for the geotechnical soil investigation visible?

Hello everyone,

can anyone tell me if the boreholes from small-core drilling and dynamic probing can still be seen after a geotechnical site investigation?

We can't seem to find any signs on our property indicating exactly where the investigations took place. This is despite the locations being marked on the site plan, even if only symbolically.

Nothing was visible at our site (gravel subsoil – topsoil had already been removed). However, the company took photos during the drilling – these photos were also part of the expert report.
