From Start to Finish: The Step-by-Step Process of Trenchless Pipe Lining

Trenchless pipe lining is a method of restoring or repairing old, damaged pipes without extensive excavation. Although trenchless sewer repair solutions have been around for over 15 years, there are still many who don’t understand how it’s done. In this article, Perry Plumbing and Pipelining explains how we carry out trenchless pipe lining in San Diego, CA. 

Sewer Camera Inspection

We begin the epoxy pipe lining process with a sewer camera inspection. This helps us to assess the nature and severity of the damage. The inspection results also help us determine if the affected pipe is stable enough to support the liner.

Pipe Cleaning

After we complete the inspection, the next step is to clean any clogged drains. We usually do this with the help of hydro jetting, which involves using high-pressure water to effectively clean the pipe and eliminate debris. This results in better adherence of the pipe lining material to the pipe, as well as lasting results.

Measuring the Pipes

Next, we measure the pipes’ length and diameter to determine how much lining material we’ll need for the trenchless sewer repair process. We measure and mix the resin based on these dimensions.

Liner Installation

Once we clear the sewer line, the trenchless pipe replacement process can begin. We use a bladder to pull the resin-filled liner through the damaged pipe and allow it to expand so that the lining can adhere to the pipe’s interior surface. We then deflate and remove the bladder once the liner hardens into a durable, fast-flow, and corrosion-resistant pipe.

Final Inspection

The final step in trenchless pipe lining is to perform a final sewer camera inspection. This allows our team to verify that everything is in place and in good working condition.
