Something to keep in mind is that if you can see that the pipe is cracked,
etc, so will an inspector if you were to sell the place.
Like another poster said, you could probably run a parallel lateral, and at
least have be able to use your plumbing while this is going on.
The actual connections at each end would only take an hour or so.
If your old pipe were to break, you'll be out of your house for days.

We need to tap into the waste pipe close to where it exits our basement
in order to get enough elevation to reach a basement sink we are
installing.

However, when we had the plumber come in, he noticed that the pipe
appears to have some hairline cracks and rusting flakes. The plumber
is afraid that if he cuts in to the existing pipe to put in a "T", he
may crack the whole pipe including the adjacent part that runs through
the foundation. Needless to say, this would be a b--ch to repair.

Any way to "strengthen" or brace the pipe so that he can cut into it
more safely?

Would putting generous amounts of JB Weld around any of the cracked
areas be sufficient? (probably not, I imagine)

Thanks
