Trenchless Pipe Lining

Perma-Lateral Pipe Lining puts new pipes inside your old sewer pipes without digging trenches. Lasts 50 years or more!

This revolutionary new technology repairs sewer and other pipes without the expense and bother of digging trenches through your patio, yard or driveway. The new pipe goes right inside the old.

This is the only system bearing the ANSI / NSF STANDARD 14 CERTIFICATION for plumbing pipe repairs. Rehabilitates sanitary pipes, storm pipes, drain vents, and vertical piping systems with ease.

The unique compressed air inversion system allows the liner tube to snake through 22-, 45- and sweeping 90-degree angles.

The Process

  1. Existing host pipeline is cleaned out with rooter machine.
  2. Video pipe camera inspection confirms if pipe can receive lining.
  3. One (1) small pothole, approximately 4ft. x 3ft., is excavated to expose pipe.
  4. One piece felt liner is treated with epoxy resin.
  5. Lining is inserted into old pipe, calibration tube is inflated and expands the lining.
  6. Lining is Cured-in-Place as epoxy resin cooks and hardens.
  7. Calibration tube is deflated and removed, video camera inspects the results.
  8. Pipe lining is a permanent, stand-alone, new pipeline.
