Long shot, I know, but anybody have a good company they have used in the DFW area for polymeric pipe lining of existing sewers? Secondary method of repair would be CIPP.

That's out of my little bubble of knowing any good contractors, this board generally comes through in a pinch though so I thought i'd give it a shot.

Not anything I know about, but could a storage tank remediation company do something like that?

Not sure but North Texas Contracting does a lot of utility work in DFW. If they don't do it they know somebody who does. Or at least they'll do it and sub it out.
