just watched a very interesting video of a method used in europe for some 20 year and
now spreading into large multistory apartment buildings. they use a videoscope and
without breaking existing plumbing lines, coat the insides of the lines with an epoxy
type (not sure of the material)

is this method known and in use in the usa? what's it called?

they calculated costs vs. the traditional method of ripping everything open and it was
less than half the cost but just as strong and insurance companies had approved it
from a liability standpoint (think moisture damage in wet spaces in buildings with 100
people)

I smell at least a little BS here. Assuming you're talking about drain
pipes:

1. They'd have to somehow clean the slime and deposits off the inside
of the pipe.

2. To be "as strong" the material would have to be of a significant
thickness which would seriously shrink the inside diameter of the drain
pipe.

Where did you get this video?

Sister-in-law in Vegas (pipes leaking in house on a slab) talking about
having this done.
Don't know outcome.

I've never seen it inside a building, but lining sewer mains is pretty
common. It's more expensive than the pipe itself but a lot cheaper
when you consider you don't have to put the streets back together when
you're done.

I just Googled for a description for you and found:

no bs as you can see from the other replies to the thread

they do, that was the videoscope part with some type of head

2. To be "as strong" the material would have to be of a significant
thickness which would seriously shrink the inside diameter of the
drain pipe.

have no idea about that but it's been in commercial use over 20 years in
germany

it was on the evening news, on network TV
