Stopping a sanitary sewer infiltration

You’ve had infiltration into your sanitary sewer system for years. You’ve tried to stop it, but short of replacement, nothing did the trick. There is another solution, however: sealing the leaks with polyurethane grout. Chemical grouting has a proven track record dating back decades to repair concrete and masonry infrastructure, yet it is still a relatively unknown practice in many circles.
