How Does Sewer Pipe Lining Work? 

The trenchless pipe lining process is most often used for the repair of old clay, cast iron and concrete pipes. 

STEP 1: Camera Inspection – This confirms location of cracks and failing joints
STEP 2: Clean Existing Pipes – Hydro Jetting debris and intrusions
STEP 3: Measure Existing Pipes
STEP 4: Preparation of Tube Replacement – Replacement piping will typically be a felt tube made of fiberglass, polyester or similar.
STEP 5: Epoxy Impregnation & Inversion of Tubing – The tube piping will be impregnated with an epoxy-resin and then inverted inside-out using a specialized inverting tool so the epoxy-resin will then be on the outside of the tubing, allowing it to bond with the walls of the existing pipes.
STEP 6: Tubing Insertion – The tubing will slide throughout the walls of the piping system until reaching final position.
STEP 7: Pipe Curing – Hot air or steam curing (4-12 hours drying time) or Bluelight LED curing (up to 5 times faster) creates the new seal. All moisture is drawn out and the new lining solidifies in place.
STEP 8: Flow is Returned to Newly Lined Sewer Pipe – Once the curing process is complete, service to the sewer line can be restored.
