Grouting Sewer Joints

[Queenofshit]

Has anyone had long term success (greater than 10 years) using test and seal methods for sewer joints? I am curious what engineers or operations personnel have to say about the longevity of fixing leaking joints by sealing with chemical grout. Thank you for your time and opinion!

I was under the impression that grout will last somewhere between 8 and 15 years. There may be longer life grouts out there. Go to Trenchlessonline and look for grout companies. De Neef and Avanti are 2 I know of. Once the leaks are stopped you could CIPP the line. Then you have 50+ years of life.
