Does anyone have experience with CIPP? Our client has a break in a PVC pipe, 9 feet below grade and, unfortunately, 4 below a column footing. I'm hopeing to avoid all of the shoring that would be necessary if we dig. Hence, I'd like to use one of the "pipe within a pipe" solutions.
Q1) do these work long term?
Q2) does the heat of curing effect the pvc pipe?
Q3) difficulties of installation?
Thanks in advance,
