I have sold so many PermaLiner jobs, now it is a waste, to many people doing it for real cheap.
I like the material, it appears strong and durable, if it is installed wrong, it does crease and look like crap. Around the bends, it will kink a bit. excellent for lateral lining, where you can stay at the property line and blow the liner. some cities here have now prohibited the installation because to many isots blowing into their sewer. Permaliner is #1 in the trenchless business.
good stuff, just to many people around here killed the market.
I have also sold alot of pipe bursting, where 2 holes are required. a bit less expensive then permaliner tech, just different requirements
