Hello everyone,
We are planning to pour concrete for our entrance platform, which will be covered either with WPC decking boards or natural stone slabs. The platform will be wider than the door opening.
In the picture, you can see the current situation. A black waterproofing strip has already been installed by the window company, and in front of it, the white perimeter insulation of the basement is visible. We have now applied a self-adhesive bitumen membrane here (not yet visible in the photo).
Is there anything we need to consider before pouring the concrete? Should XPS boards be applied to the render?

Yes, standing water or occasional heavy rainfall isn’t the main issue. A drainage channel or simply a slope away from the house is usually enough. But in Berlin, over the past 10 years, there have been two severe rain events where people had to wade through water ankle- to knee-deep, and subway stations were flooded (I believe someone even drowned during one of those events). In such cases, having 40 cm (16 inches) of extra height before the slag runs into your house is a relief... The water just needs to be able to drain away. And not just a little, but completely. Despite poor drainage conditions, we still plan for a ground-level design. The concrete slab will extend well beyond the house, and the screed will be added on top. That should raise it high enough to create a proper slope away from the house and across the property.

The concrete slab already protrudes quite a bit, and then there's the screed on topAnd insulation plus the service layer, and then you end up with a step, like we do

For us, it will probably end fairly close to the original ground level; I will likely need to excavate a little bit more beforehand. But we’ll see how it turns out with the screed.
