Flexible, small dia. conduit

    I have some extensive pre-wiring to do in and around a very ornate hardscape. I need to be running wire up knee walls that will have a rubble stone veneer applied to them. As there is so much mortar used in rubble wall construction I want to be able to protect the wire jacket from the lime in the mortar.

    Do you know of a small dia. flexible, thin wall tubing or conduit that I can use for this application. I checked in at HD and found 1/2 poly pipe, but it is too thick and rigid for the application.

    Thanks.

    Have you checked with an irrigation supplier? Maybe they have some type of drip tubing or the like that would solve your dilemma. I know this is a stupid suggesion, but I can't think of another at the moment. How fast would the lime deteriorate the jacket anyway?

    Yeah what Chris said. Go back to HD and look in the irrigation area and look at solid drip tubing. The you can paint it to match the stone.

    The wire will be installed inside the conduit and then anchored to the cinderblock foundation of the wall, then the mason comes and applies the rubble limestone finish to the walls to complete... completely covering the wiring except for a pigtail that comes through the stone/mortar to allow for some flush mounted louvered downlights.

    Depending on the mortar used, I would think that a cable might only last 10 years or so in there. The lime in the mortar will eat through the jacket.

    Regards

    So how much life do you think the drip tube idea would provide? Another 10 years maybe?

    I am hoping so, at least that...

    I am actually thinking about using 12/2 BX but not sure if it is rated for the application (inside a masonry wall)

    Regards

    Not sure what 12/2 BX is. Does canadian code specify that it would have to be in conduit for this application being that it is not a wall of the dwelling?

    is the cinderblock built yet ? I am doing about the same thing now but speced the conduit to be exactly where I want it during wall construction. They simpy made hole in the cinderblock and stubed the conduit out. I can cut it off and just fish tape my wire up fom the base of the wall.

    refridgeration tubing ??

    James,
    Take a look at the PEX tubing. It is commonly used for plumbing where you will need very flexible tubing. Usually what you see under sinks. This stuff is very durable.
