ᐅ Pulling cables through a conduit (or duct).

How long is the conduit? Do you have a fish tape or pulling tool so you don’t have to use the wires?
The cables are probably stacked on top of each other, which could be blocking the pull.
Once you reach 10 meters (33 feet), it gets quite difficult. As @Fummelbrett! already mentioned, it’s important to use plenty of lubricant.

I just measured, it should be close to 10 meters (33 feet).

I only have those nylon pulling guides from the hardware store, but they’re not very effective. I was able to push another empty conduit with an 18mm (0.7 inch) inner diameter up to that point. I plan to insert an inspection camera there to see why it won’t go any further. After that, I’ll figure out the best plan moving forward.

Hello,

The endoscope arrived, and I tried it right away. It doesn’t look good around my empty conduit.

At some point during construction, it must have been damaged.

There are definitely stones inside, and it’s no longer perfectly round.

There is still space available, but the question is how I can get through there.

What type of conduit did you use? Normally, it’s quite difficult to damage...

What a pity about the conduit.
Get some lubricant and also slightly move the other cables. Most likely, use the 5x16 one. The insulation there is much more durable than network or coax cable. It only has to slide through the corner once. I don't really see an issue with a doorbell wire. But that would be the limit.
Your plan to use the existing network cable and skip the doorbell wire isn’t going to work?

So, hours later. Nothing gave me any peace of mind, so I lifted the paving and once again cut through compacted mineral aggregate. As is often the case in life, I got unbelievably lucky—the pipe was probably damaged during the installation of the thick point foundations for my mezzanine roof.

So now there is a huge mound of concrete over my broken pipe.

For the time being, we’ve connected the doorbell to a network cable. But I want to fix it properly. We are supposed to get fiber optic installed here. I already have a duct from the house to the street that runs over the garage. My plan was for them to put their cable inside that without destroying my entire property again.

You have 1100m² (11840 sq ft) of land, and concrete and duct come together to the millimeter.

The empty conduit now appears to be the weak point. Isn’t it possible to lay the new cable next to it as an underground cable or in a new conduit? The camera and related equipment cost a significant amount.
