    I am running a cold water feed to my shed, about 10m from the house. The house already has a cold water tap on the outside, and I intend to plumb into it (keeping the tap for garden work) but having a permanent feed to the shed.

    I am digging a trench to the required depth (~750mm) but within the last metre or so of the house there is hard concrete about 4 inches under the soil.

    This means I cannot simply dig the 750mm trench up to the side of the house like I had hoped.

    Presuming this is the foundation, it would be a tall order to cut a 750mm-deep notch into it. Is there another way?

    The pipe is blue polypropylene; can I use an insulted jacket on it and then concrete it in to a smaller channel I could cut into the concrete for this last metre to the house? I could use an elbow to get it tight to the wall before angling upward toward the tap. This would need to be insulated anyway.

    Any other possible solutions? Thanks in advance - Colin.

    Look at insuduct, not cheap but works well

    To comply with regulations, you would need to speak with your water undertaker and ask for a shallow lay. Also mdpe isn’t recommended for above ground connections.

    You can use the insuduct groundbreaker, I've used it for a water main that was forgotten on a new build so had to bring it up out of the ground and up the wall then through wall 6 inches above floor level.
    They also use it for flats so can run up side of buildings in mdpe.
