Plenty of products promise to make underground repairs as unobtrusive as possible.
Feltner was recently called in to repair a drain line under the kitchen floor of a hospital. Not that long ago, about the only way to conduct such repairs was to rip up whatever was covering the line before you could literally get to the problem. That usually meant a headache for the sewer and drain line owner, to say nothing of the other aches and pains associated with the “reconstruction” costs of putting everything back in place.
