ᐅ Base insulation cover XPS/dimple membrane

Hello,
we are insulating our exterior wall and I have installed 120mm (5 inches) XPS boards as perimeter insulation, which extend about 40cm (16 inches) into the ground and about 20cm (8 inches) above it. A dimpled membrane is applied over these and then backfilled.
Above that, 140mm (6 inches) mineral wool insulation boards will be added.

Now to my question:
As far as I know, the dimpled membrane is pulled up above the ground level. How can this be properly covered or concealed so that the splash water area is finished neatly?

Attached is a sketch for illustration:
Thank you very much for your help.

Hi mundele,

I'm not an expert here. Off the cuff, I would cover it with drainage fabric.

Best regards

My initial gut feeling would be to cover it with drainage fleece.

However, this fleece should be the dimpled type. I would suggest the following setup:

Concrete, then fully apply XPS insulation boards, and finally the dimpled membrane.
