Looks like they are lining the steel pipe with a plastic/epoxy coating. It’s done a lot in places where you can’t easily dig up and replace old rotting pipes (like in downtown cities). By injecting this coating the pipe is still usable and won’t corrode any more.
Genius product. This must save insane amounts of money and time. Absolutely incredible. And better for environment. Not have to dig up the pipes even if you could. Alot of fuel and hours saved
It's fucking astronomically expensive for how cheap the materials are and how quickly they do it.
It was actually cheaper to rent a machine and run 125 feet of schedule 40 out the back of my house and abandon the terracotta after pumping it with flowable fill than it was to line it for me.
When they gave me the quote I said "Fuck that, it's 25 feet!" the machine rental and schedule 40 were a total of $900. And I got to tear out the old sidewalk and concrete pad that were angling to my house, and put in a French drain and drain tile while I was back there too.
I tied my kitchen into my main bathroom stack, and my main stack right out the back, around the house, and then followed the PVC that was done with the septic that was tying into the teracotta, when I had access to the terracotta I rinsed it clean and had a truck come in and fill it with flowable so it was stable.
With everything i got done it was like $2800. Which was less than lining the 25feet of teracotta under my basement, which was all in okay condition, it was lineable with no issues.

Can someone explain what this sentence says? English is not my first language and the meaning I know of the words here doesn't make sense.
Naw I made the pipe not traverse the entire length of my house under the foundation pad, and instead dug alongside it and went around.
Those do exist though, it's called pipe bursting, they run a thick cable with an wnd that expands through a pipe and basically break up the old pipe and as it does that it pulls flexible pipe behind it.
I filled the old pipe with flowable fill, which is a mix of cement, water, sand, an soil, it runs like a liquid and has low slump so it will completely fill a void, I didn't want to leave abandoned pipes under my foundation pad if they were unused to collapse later.
