Is this around the norm for 100M of Gaine préfilée ? Do I save much by buying the individual cables and conduit and filling myself?
Seems a lot of dosh for 100M

I can’t offer any informed opinion except that 25m from Bricomarche is about 47€. I was in there today and I happened to notice how expensive it was. It all seems very expensive these days. I just checked on their website and notice that 100m is only 116€ and 50m is about 60€.

Cable prices are silly money now.
The bare gaine has also gone up but if you have a source of cheap single core cable then you can do your own thing, I did about 7 years back using flexible conduit wire.
To fill a 100m couronne you need a 200m straight unobstructed run and something to tie the draw wire to.
You pull the conduit over the cable and not the cable through the conduit.

We never used it, Câble only, easier to run and way cheaper. The only gaine we used was when we wanted to make up 'peculiar runs eg 3 x2.5 + 4, 5, 6 or 7 x 1.5 etc or for passing câble through walls and metalwork.

If you have enough airspace between them it would work for a while Bare wire = uninsulated conductor. Wire = insulated conductor. Câble = 2 or more insulated conductors covered encased inside another insulation (double insulation) Google.fr R02V, H07VU etc

I never knew that câble should have a circonflex, thanks for that!

Not being an electrician as such , I would always use gaine in walls that would be plastered and cable if there was access for later.

If you have any past signs of rodents in the house, then use the hard plastic conduit for everything - I mean everything, even simple two wire internet feed! Avoid cable as they love the soft round cable to sharpen their teeth...

I used the PER multi-couche water pipe to span under my now ex chalet in the UK, it had to be fed into the shallow void from underneath and connected via access holes bored in the floor.
It has a hard aluminium layer, more than one possibly surrounded by PE, I then put a foam pipe insulation sleeve over it.
One winter I found the hot water from the ballon was not getting up to heat, the mice had chewed their way through creating a 24/7 spa!
They are more than capable of chewing through the gaine plastic but its larger diameter means they cannot open their jaws enough to get a bite, I think 16mm is pretty much the lower limit.

Not being an electrician as such , I would always use gaine in walls that would be plastered and cable if there was access for later. The normes require that gaine be used anywhere that is not accessible or visitable, I was very surprised at Le Dollys comment, whilst I completely agree as a professional electrician either he was running all his wiring surface mounted or was indeed using gaine in cloisons, above ceilings etc.
I made my own interpretations, I would use gaine to/from the interrupteur (dry lined cloisons) and above the suspended ceiling to the central DCL lighting fitting but when I fitted spots I used cable from that fished to and from each hole for each fitting, I used larger LED spots so that I could et my fist through.
My God fearing French self-builder friend struggled with gaine for each and every fitting.
The principle is that any wire/cable must be able to be withdrawn and replaced from inaccessible areas, with gaine this is usually possible if the max number of conductors, bend radius etc are respected.
Another advantage of gaine is that if the correct length plasterboard screws are used (yes there is a norme for that also) then you cannot drive a screw through a cable, if a longer screw is used and the gaine is not overfilled its nigh on impossible for the screw to cut through to a conductor.

Its only 6 Euro's cheaper? Do you have a cheaper source? It is almost half the price of the gaine préfilée that you linked to.
