My back yard drain (partially under cement) is the old orangeberg pipe. When it is snaked out to remove and roots etc I am now receiving parts of the pipe. Total replacement would be tremendous. Can one sleeve orangeberg and is it economical? Can one use  the epoxy liner to fix?

Richard, Orangeburg pipe, also called “fibre conduit”, is made from made from layers of wood pulp and pitch (for more information, see the article on Wikipedia here). Because Orangeburg lacks in structural integrity (even when it was new), it’s not a suitable host pipe for epoxy lining. It might be possible to sock line Orangeburg pipe if enough of it is intact, but you’ll need to consult with a company that offers these services to find out. The North American Society for Trenchless Technology’s website, is a good place to start looking for companies that offer different trenchless solutions that might have a solution for you, or at least offer additional insight.
