Thanks to today’s technology, there’s no need to dig up floors and knock down walls anymore in order to replace bad drainage pipes. Structural pipe lining (also called cured-in-place-pipe lining (CIPP) or just pipe lining) is a minimally-invasive method for rehabilitating damaged sewer pipes instead of replacing them.
Pipe Lining is…
- Less expensive than invasive, traditional sewer line replacement where your damaged pipes are dug up and replaced with new ones.
- Fast. It can be done in a day.
- A solution that lasts. Lined pipes have a 50-year life use expectancy.
- Minimally-invasive. Unlike traditional methods, pipe lining doesn’t require heavy excavation. We just need access points to get at the pipe.
How Sewer Pipe Lining Works
The short answer is that sewer pipe lining creates a new pipe within your old, damaged pipe. Here’s how it works…
- Your pipe is first inspected by a CCTV sewer camera. This inspection is non-destructive and takes about 30 minutes to complete. We access the pipe via clean outs, a vent stack opening, or by removing a toilet. (Don’t worry. We’ll put it back together again when we’re done.) The sewer camera inspection not only measures the pipe‘s linear footage, but looks for problems as well. Things like cracks, invasive tree roots, and blockages.
- The pipe is then cleaned thoroughly via hydro jetting or some other method. This is done to remove any blockages such as tree roots or build up. Sometimes, sewer cleaning is all that is needed to solve recurring blockages. The goal of this thorough cleaning is to restore the pipe’s original diameter size.
- Now that the pipe has been inspected and cleaned, the lining process can begin. A felt liner – cut for the pipe’s dimensions – is saturated with a special epoxy and then inserted into the damaged pipe. A bladder on the inside of the liner is inflated. This pushes the liner up against the inside walls of the pipe, taking its shape. After it has cured for several hours, the bladder is removed, and you now have a brand new pipe within your old pipe.
- The next step involves reinstating any branches that were covered over during the pipe lining process. This is done robotically using special equipment.
- The final step is the post lining inspection to make sure everything is OK.
Sewer lining is not something that can be done in a few hours by one plumber. It takes 3-4 plumbing technicians, a half-day of preparation, an entire day for the installation, and then a few hours for the final inspection. Only certified and experienced plumbing technicians with the necessary special equipment should perform sewer pipe lining.
The Benefits Of Sewer Pipe Lining
Traditional sewer line repair is invasive. Therefore, the number one benefit of trenchless pipe lining is that you can repair a damaged sewer pipe without trenching through your living room.
Trenchless sewer lining is minimally-invasive and allows plumbing technicians to fix a damaged pipe without destroying property. That means that after the repair is complete, you don’t need to worry about paying someone thousands of dollars to rebuild destroyed floors and walls. This saves you both money and the stress of seeing and living with extensive property damage for a period of time.
Pipe lining is not a temporary solution. Your newly lined pipe has a life-use expectancy of at least 50 years.
What Pipes Can Be Lined?
Sewer lining can be used on any sewer pipe that’s structurally sound. In other words, a pipe that still has its basic structure. Since the liner used in sewer pipe lining takes the shape of the host pipe, it can’t fix problems with the pipe’s pitch or slope. Pipe lining also can’t fix a collapsed pipe.
CIPP can be used on sewer pipes that have corroded over time, or have cracked and are now experiencing problems with invasive tree roots and soil. After lining, the roots and soil won’t be able to get back into the pipe.
Trenchless lining can be used on…
- Residential, commercial, and industrial sewer pipes
- Vertical vent stacks in kitchens, laundry rooms, etc.
- Lateral lines
- Building mains
- Branch lines
- Rainwater leaders
- Underground storm lines
New Flow Plumbing does not offer pipe lining to repair cracked potable water pipes.
How Much Does Sewer Pipe Lining Cost?
The cost of pipe lining depends on a variety of factors including the length and condition of the pipe, the ease of navigation, the amount of cleaning needed prior to lining, and the accessibility of the pipe.
At first glance, pipe lining seems more expensive than traditional sewer repair. However, once you figure in the fact that you don’t need to pay thousands of dollars to repair the damage caused by big trenches, you actually end up saving money.
