Hi, we are just about to hand over the house, and recently the site manager mentioned casually that we still have to apply a bitumen layer on our base, which is already plastered. And it should be as high as the earth will be backfilled.
The other site manager said only over/up to (?) the perimeter insulation.
But since you never see the guys and when you do, they are very short with you, it hasn't been properly explained to us so far how far we really have to do something.
Under the base plaster there is pink styrofoam, which in turn was glued on with bitumen (without any nasty sticky black stuff).
Do we really have to apply another bitumen coating now? Or is an insulating coating based on bitumen enough? Or maybe a flexible sealing slurry?
Everyone says something different -.-
There are way too many different types of bitumen. No idea what the right one is.
Attached is a screenshot from the contract regarding the sealing.
I also do not see anywhere else that anything else still has to be done by the builder.

Here you can see part of the base
