    piping loops

    When deep verticle holes are drilled how do they make the 90's at bottom to come back up ? And what is grouting ?
    TIA

    The tubing comes with a 180 u bend already attached. Grouting fills the bore hole with a thermally conductive material.

    Some companies also plastic weld a double 90 at the desired depth (I think a preformed 180 is a better idea personally)
