Hey guys,

Has anyone had experience with Perma-liner or similar trenchless CIPP (cured in place pipe) repair?

We have a manufacturing plant with sewer piping in bad shape due to chemical attack.

I thought this might be a good option.
There is a lot of equipment/piping/electrical that would need moved to excavate the old piping, so that is why I'm thinking this could be a good option.

Regular diluted acids and caustics and hot condensate in contact with the piping.

There are three or four lateral connections to the main line, so I need to ask how they handle that, and also the hotter fluid temps.

I'm hoping someone has had had - or knows of a similar situation and how it was dealt with.

Thank you
