Cured in Place Pipuing - Pipe Repair

Cured in Place Pipuing - Pipe Repair

Cured in Place Pipuing - Pipe Repair

(OP)
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,

Imagineer


RE: Cured in Place Pipuing - Pipe Repair

To answer your questions: Q1 generally cipp lasts 50+ years.
Q2 Depends on the system that is used. But in general no.
Q3 The difficulties of installation are varied from site to site. You do not give enough information ie.. What size is the break? Is there groundwater present? If so what is the hydrostatic head? If it is only one break you can do a spot repair if several you made need to do an entry point to entry point. What size is the host pipe in dia? These are just a few of the questions that would need to be answered to give a better response to your inquiry. If you want you can e-mail me at dwain64@hotmail.com.
