Underground Cable conduit

[dal]

Hi so I'm going to be laying a new patio & I want to run some cable underground before the patio is laid, the cable is for 12V for RGB lights, but I want to have a number of T juntions along the route so individual cables can branch off ( one for each light ). Can anyone suggest a underground conduit suitable for this sort of thing. I know I could buy a long reel of the stuff but it's not ideal for my needs as I would have to 'break in' to it every meter.
Cheers

I've used waste pipe for running the cabling to the LED lights and robotic mower.

I used 40mm solvent weld as I already had quite a few bits but could equally use 32mm or push fit connectors.

Just don't expect to be able to pull cables through with T junctions, they will get caught.

Thats not a bad idea actually, I reckon if I used 40mm pipe with T junctions it would be ok to pull the wire through as the wire is quite small, maybe I'll experiment with that, cheers.

Why don't you just use the proper stuff - either 20mm or 25mm electrical conduit -you can get any type of joint configuration you require.

Given how cheap the plastic waste pipe is & that I can get 40mm I think it will actually be easier to work with for my needs. The proper stuff would come to a fair bit in comparison.
