    I am planning on putting a concrete base down in my garage
    Plan is to dig out and put 100mm of hardcore and 100mm concrete on top
    The garage is not used for a car, its more of just a store room
    The garage is also NOT accessible directly from the house
    My central heating boiler is in the garage and its gas is fed by a 22mm pipe which as you can see from the pictures attached, exits my kitchen wall, drops downwards (see pipe to left of the air brick) into the ground, and then pops up approx 2m to the right before re-appearing and going off to the boiler
    I seem to recall the depth of this pipe is approx 12" below ground and again, i seem to recall being told that the pipe is wrapped in Denso tape (see Denso.jpg)

    Obviously i would rather not have to pay for the gas piping to be modified to have to be visible on my outside wall so my questions are :

    Q1 - Is it ok to have a standard 22mm copper pipe wrapped in Denso below ground ?
    Q2 - If yes, can i concrete over as described above ?
    Q3 - Where the concrete meets the pipe, is there any other barrier or distance needed other than the thickness of the Denso tape, to stop the concrete reacting with the pipe ?

    The red line on the photo is where i plan for the concrete base to come to

    Can anyone advise please ?

    Many thanks in advance

    Lol. I've dug ancient (unprotected) copper pipes out of concrete showing only signs of surface blemishes. The copper and soldered joints was fine and intact.

    Crack on. Just cover it in soft sand and warning tape. Sleeve it in plastic if you want, but I would not bother as long as its wrapped in Denso.

    It is extremely dangerous to bury gas pipes under structures, that is why it's not allowed.

    Incorrect.

    It is forbidden to build over a gas service. Please don't post where you are not qualified.

    I am qualified, and you are extremely irresponsible to suggest otherwise.

    Domestic gas (as long as it is protected against corrosion) in concrete is allowed.
    Do stop posting rubbish.

    I said, and I am correct "It is extremely dangerous to bury gas pipes under structures, that is why it's not allowed."

    And you said "It is forbidden to build over a gas service." an answer open to interpretation, probably deliberate. You can build a path over a gas pipe but you must not build a structure over a gas pipe, doesn't matter what size or who owns it, end of.

    And as you're doubting my qualifications to comment, what are you're qualifications for being a builder?

    No, it is not open to interpretation. The gas 'service' ends at the meter. Domestic gas pipes can be buried in concrete - i.e. built over.

    So you have twisted my words, seems you are atypical dodgy builder that makes ridicuolous interpretations of regulations so you can earn an extra few pounds.

    You are an incompetant highly dangerous fool, lets just hope your cavalier attitude doesn't kill anybody. And remember your word play doesn't fool me and certainly won't fool a prosecution barrister.

    If you don't know what a 'service' is, then you should not be preaching about gas.

    Stick to decorating boyo.(y)

    And the insults start, I must have touched nerve, are you thinking about all the gas pipes you've buried under structures and the consequent possible explosions? Or perhaps you couldn't care less.

    Edit - I just looked up where staffordshire is, and see that birmingham is slap bang in the centre. Always dreaded doing jobs in Birmingham, every job was a pain due to low skilled labour and their bosses that couldn't understand regulations. Explains a lot.
