Does the builder have to hand over the soil report?

We have a heavy clay soil that may have been further compacted by the construction, I’m not exactly sure. But here you can dig a hole, for example 50x50x50 cm, pour water in, and after two days it’s still almost just as high. We don’t have visible puddles though; apparently there are enough permeable spots on the surface. We have accepted it; after all, we live on a clay slab. Trying to just twist a holder for the sunshade into the lawn? You can forget it. The carpenters also swore quite a bit while digging the foundations for the carport. You really can’t do much if it’s not just the top layer. The "positive" side: we have no moles here. Apparently it’s too tough for them as well.

As long as the water does not stand at the building or similar and disappears from the lawn within a reasonable time (I find puddles after rain normal at first), I would accept it, because I believe truly helpful measures are not proportional to the benefit.
