ᐅ Insulation at the door threshold — similar to paving?

Hello,
in the picture you can see the insulation with the door behind it. Now I want to install a block step or patio slabs level with the door threshold.
For this, I need a proper substructure. The insulation is in the way.

What should I do?

Cut it away?
Simply build up with concrete?
Just put a slab on top with recycled material underneath?

I would appreciate a few links or tips.

Thank you very much

I’m not entirely sure what you are planning, as it’s not clear from the picture. How will you handle drainage if you want a flush floor connection? How is the door sealed?

So, we have a canopy with a depth of 2m (6.5 feet) and a width greater than the front door. I haven’t really considered your questions yet. Drainage is managed through the slope and the canopy.

A roof covering helps, but even then you can have driving rain.
A ground-level door usually requires two sealing layers and a drainage channel.
No one can force you. If it is properly roofed, it can work without a drainage channel, as long as it is well sealed and the surface has sufficient slope.
Just keep this in mind.

So, I asked around again among friends and a site manager.

The latter suggests that I should cut away the insulation.

Another person said that if I properly seal the insulation from below and from the sides, it won’t move.

The door has a roof of 2.7m (9 feet) and on one side a wall, on the other side a roof that extends 1m (3 feet).

Of course, I’m installing it with a slope. I’m still considering whether to wrap the insulation or cut it away.
