Pipe LiningPipe Lining

Pipe Lining is a process used for repairing and replacing cracked, leaking, backed up, and damaged sewer lines. Using a “no-dig” trenchless process to avoid yard excavation, sidewalk destruction, or digging up trees, sewer lining involves inserting new epoxy-saturated pipe tubing into existing pipes, inflating the tubing, and curing it into place with hot air, steam or Bluelight LED technology. This results in a new seal lining the walls of existing pipes, replacing broken piping with the potential to last for decades.

How does sewer pipe lining work?

Most often targeting the replacement of clay piping, cast iron, concrete, plastic, and PVC pipes, the trenchless pipe lining process involves these steps:

  • Sewer Camera Inspection – To confirm the position of cracks and compromised pipes
  • Cleaning Existing Pipes – Removing debris and other blockages
  • Measurement of Existing Pipes
  • Preparation of Tube Replacement – The replacement pipe tubing will typically be a felt tube made of fiberglass, polyester, or similar materials
  • Epoxy Impregnation & Inversion of Tubing – The tube piping will be saturated or “impregnated” with an epoxy-resin and then flipped or “inverted” inside-out using an advanced inverter drum so that the epoxy-resin will be on the outside of the tubing, allowing it to be affixed to the walls of the existing pipes
  • Inserting Tubing Throughout the Compromised Pipes – The tubing will slide throughout the walls of the piping system until in place and ready for curing
  • Curing of Tubing – This is what creates the new seal. Using popular technologies — traditional hot air or steam curing (4-12 hours drying time) or Bluelight LED curing (up to 5 times faster), all moisture is drawn out and the pipes can solidify in place
  • Sewer Flow is Returned to New Pipes – Service to pipes can be restored once the curing process is complete.
