Hello everyone,
in most constructions, you can see that a "membrane" (I can’t recall the exact technical term right now) is placed between the concrete slab and the masonry to prevent rising dampness.
In our shell construction, from what I could observe, this seems to have been omitted. Before I discuss this with the site manager, I wanted to ask for your collective knowledge to find out if this is normal, what the possible reasons might be, or other relevant information. Maybe my concerns will be resolved already.
I’ve attached a photo. If it had been done, you would see it, right?
Best regards

already sealed from below and therefore dry,That is probably more wishful thinking than reality. The material itself may be waterproof, but it’s not made in one solid piece. In the simplest case, the panels are just butt-jointed. So, of course, there are gaps. Water can also run behind it from the sides.

Naturally, there are gaps. Water can also run behind the sides. In our case, all joints are sealed with foam, and the external insulation on the sides fits seamlessly. In addition, there are polyethylene and aluminum foils under the rigid foam boards. That should make it reasonably watertight.
