ᐅ Moisture Sealing of the Concrete Slab

Hello everyone,
for better moisture protection, the waterproof membrane will then be extended up along the exterior walls, similar to a basin.
When I mentioned this to the builder, they responded:
the waterproof membrane will NOT be extended up the exterior wall.

The installation complies with the requirements of the DIN standard.

How necessary is this? Should I insist on having the membrane extended up the wall?

Are the walls built on waterproofing membranes? Raising them up is not necessary; whether you want to insist on that is up to you, but I think your builder will be unlikely to agree with you on this...

It seems that the damp-proof membrane is also missing.

Yes, what did they put under the masonry?

Something can be seen beneath the masonry

This can somehow be read between the lines from the builder’s response.
