Lay satellite cable and terrestrial cable into the house

Hello everyone,

next, I am coming to the topic of electricity in our house construction. I now want to lead 3 underground cables outside and 4 satellite cables into the house. Is it enough to simply use a conduit and then foam it up with well foam? Is that then waterproof or do you have to use special feedthroughs?

Thanks for your help

Basement or no basement available?

Oh forgot, no basement Kfw 40 if important. Cladded / brick

How do the suppliers enter?

According to the old scheme, kg pipes

Run power and satellite cables in separate empty conduits, please.

If you want to seal the conduits with foam, that will work, but only fill a few centimeters of the conduit with it; otherwise, you'll have trouble if you need to access it again.
