Does anybody have any suggestions for easier/faster ways to bore under sidewalks for getting pipe under? I've been using the old post and sledge hammer approach, but I seriously need to have a better way. The trick is that (and get ready for this)... On the sites I need this the most, I have no access to a hose bibb, so tools like borit won't work. Unfortunately, one of the MURBs (Multi-Unit Residential Building sites) I'm doing poured all their sidewalks and forgot to drop sleeving in. Any ideas?
