How Does Pipe Lining Work? 

In the greater Seattle area, we use the trenchless sewer lining process to repair old clay, cast iron and concrete pipes.  First, A Camera Inspection – Locates cracks and confirms failing joints. Then, We Clean Existing Pipes – Hydro Jetting clogged sewer debris and root intrusions. Next, We Measure the Existing Pipes To determine how much lining material is needed. Additionally, Preparation of Tube Replacement – Replacement piping is typically a felt tube made of fiberglass, polyester or similar. Epoxy Impregnation & Inversion of Tubing – The tube piping is impregnated with an epoxy-resin. Then it is inverted inside-out using a specialized inverting tool.  As a result, the epoxy-resin is then on the outside of the tubing, and bonds with the walls of existing pipes. Tubing Insertion – The tubing slides throughout the walls of the piping system to reach its final position. Lastly, 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. Ultimately, all moisture is drawn out and the new lining solidifies in place. Finally, Flow is Returned to Newly Lined Sewer Pipe – Once the curing process is complete, service to the sewer line is restored. As a result, the life of your existing sewer line is now good to go. Potentially, for several more years of trouble-free service!
