Eliminate Unnecessary Digging Historically, repairing a pipe meant accessing the pipe where it was damaged in order to replace the damaged portion with new pipe. In the Cincinnati area, this meant excavating (digging) a large enough trench to be able to access and repair the pipe, no matter what length or depth the pipe was, or what stood above it (trees, driveways, production floors, retail space, etc.). CIPP (Cure In Place Pipe), also known as Trenchless Pipe Repair or Pipe Lining, eliminates the need to excavate. Instead, the old pipe is lined, creating a brand new pipe inside the old one, which has made the process very popular with our residential, commercial, industrial and municipal customers in Cincinnati, Northern Kentucky, Southwest Indiana and beyond.
