Electrical conduit

[Moonshine]

This is similar to my post here, that i need to get electric ducting in under a floor space, on a similar run to the water.

I also need conduit for connecting the house to the garage at about a distance of 25m and will need a fair bit. Is this type suitable?

i presume something cheaper like this is not suitable due to rippled inside

Can electric and internet / phone share the same duct?

For the garage electrics the choice is yours.

the flexible cheap stuff is fine but difficult to pull anything through. If you are putting the cables through first and then burying it, it’s fine.

As a minimum I would use the 50mm twin wall over the other option you proposed 

 

I prefer to stick to 100mm twin wall, gives future flexibility for adding extra cables.

 

swa cable and exterior grade data cable will be fine in the same duct.
