ᐅ Multi-utility house entry – routing cables out of the building

Hello,

I have watched a few videos about multi-utility connections. In our case, the gas line remains unused.

Can we use this connection to route cables out of the house? We need to run two thick power cables to the garage for further distribution, 3 double LAN cables, a KNX cable, 2 telecommunications lines for the garden gate buzzer, 3 x NYM 5-core cables, possibly a vacuum hose, power supply for a cistern, a power cable for an awning motor, and I’m sure I’ve forgotten a few others.

How do you seal it properly?

The telecom section, as I have seen, has 4 sub-ducts. I need 2 for telecom purposes (copper cable and empty conduit for fiber optic). That leaves 2 sub-ducts free. Can I use those for something else?

Thanks for your answers.
