If the leak is in a main sewer line (4"), you might look into using the "trenchless" sewer line replacement. Otherwise you have only two options: 1) cut into the building drain before it goes under the inaccessible part of the house and reroute it; or 2) perform a major excavation along the existing line and lay new pipe there.
