Sewer Lining

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!

The Benefits of Sewer Lining

Homes and businesses turn to trenchless sewer lining for many reasons:

  • Because excavation of property is unnecessary, this saves landscaping and walkways
  • Location of underground utilities is not necessary
  • Significantly hinders root intrusion and slows erosion of pipes, giving your sewer line new life for several more years
