Emergency Trenchless CIPP Under a Marble Patio - The Gulch, Nashville
A rental property in The Gulch had a failing sewer line, and the failure ran beneath an expensive marble patio. Prodigy restored it with trenchless CIPP relining in about three hours, with zero excavation and the patio left completely untouched, for an estimated $16,500-$28,000 less than excavation would have cost.
The Challenge
The property's sewer line was failing, and the root cause sat in the worst possible spot: an offset joint where a PVC section met an older cast iron section, directly beneath an expensive marble patio. A prior plumber had already worked the problem, fixing one pipe, but missed the actual root cause, so the trouble continued.
Excavating to reach an offset joint under a marble patio would have meant tearing out and rebuilding the hardscape - exactly the kind of collateral damage that turns a sewer repair into a five-figure restoration project.
Our Solution - Trenchless CIPP
Rather than dig, Prodigy diagnosed and restored the line from the inside. A CCTV sewer camera inspection located the offset joint and confirmed the real root cause the previous plumber had missed. After hydro jetting to clean and prep the pipe, the team installed a CIPP (cured-in-place) liner, creating a new, jointless pipe inside the failing one, with the marble patio never touched.
