Hello
Due to the fiber provider's unwillingness to place the fiber receiver in a sensible location, I have been forced to make a hole in the basement wall to run a network cable. Since both the inner and outermost layers are so-called dyonit panels, the hole became unsightly large.
Is it safe to fill with foam around a flexible conduit without it being compressed?
I then thought about plastering with house fix or suitable mortar near the surface.
Does plaster/mortar adhere to foam?

If this is asked in the wrong category, maybe the mod. can move it?
