  • 1.  Pipe Lineability

    Posted 9 days ago
    Hi ASCE Community,
    I want to inquire - is this pipe spot lineable in your opinion?  There is a lot of utility conflicts above to open cut, so I'm wondering if this is lineable.  In my opinion, yes it appears to be lineable since there's nothing obstructing the lining apparatus.  I am not looking for perfection and recognize the finished product will not be perfect but expecting it to be stablized.  
    Thanks in advance,
    Michael

    A CIPP lining might be a viable option. You would probably want to spec a fully structural liner thickness.

    If there is enough vertical clearance between the other utilities, pipe bursting might be another option for you.
