ᐅ Is it always possible to install empty conduits without any issues?

Hello,

we have a newly built semi-detached house.

I wanted to have several empty conduits installed to allow for future upgrades.

I planned to have 2 empty conduits installed from the roof down to the basement for:
- photovoltaic system
- satellite cable

And I also wanted to have one installed from the basement to the garage.

I wanted to know if empty conduits can always be installed out of sight?

Also, I wanted to ask how much these empty conduits cost (including installation) per linear meter.

Is it easy to pull cables through these empty conduits later on?

We have also had various conduit pipes installed, which are mostly laid "out of sight," but I cannot yet tell you the cost per meter (per yard). Later, you can implement your plans using these conduit pipes without having to break open the walls.

It is important that your planning is discussed and coordinated with the relevant workers (electrician) before pouring the foundation or other masonry elements.

Although it may seem obvious, the electrician must of course ensure that the minimum bending radii are observed and that the conduit is not crushed, etc. – otherwise, it will be impossible to pull the desired cables through later.

Make sure to install a conduit during construction that will later serve as a guide to pull cables through. Ensure the bend radii are as large as possible. For long distances (more than one floor), I would currently recommend installing an intermediate junction box so you only need to pull cables one floor at a time. In an installation shaft, a service hatch in a discreet location is useful where two empty conduits meet, allowing cables to be pulled through one after another.

When laying conduit in screed, use so-called armored conduit that cannot be crushed, maintaining the effective cross-section.

Maybe you should also consider arranging a chat with your general contractor to discuss your questions 😀

No one can probably tell you the exact cost here. Conduits or empty ducts are generally always possible, but I would only have them installed where I actually plan to use them later.

During planning, I was also warned that condensation can form inside the conduits, which might lead to moisture problems. However, I did not look into this in detail.
