Fixing Root Intrusions in Sewer Pipes: 4 Reasons You Should Be Using CIPP

Broken sewer line? Here's how to fix root intrusions in sewer pipes with less hassle (and less cost) for homeowners.

Trees and bushes are serious about finding water sources. And that raw determination can cause substantial damage to anything in their path, including sewer lines. Homeowners who have experienced root intrusions know how serious that damage can be, and they know that fixing it can be expensive, time-consuming, and frustrating.

So how should pipe repair businesses fix root intrusions in sewer pipes with as little disruption as possible, and with a less shocking repair bill? With all the methods drain cleaning and repair companies have to choose from, the option that covers the most needs is CIPP repair. With its fast, noninvasive process, fixing root intrusions is simple and effective for decades.

Key Takeaways

  • Temporary fixes for root intrusions can be less expensive, but often result in having to deal with more intrusions later on.

  • Some permanent options are viable for long-term solutions, but can damage property or extend downtime for homeowners.

  • CIPP repairs reduce downtime, maintain property, and provide root intrusion elimination for 50+ years in many cases.

  • Pipe repair companies with a pipe lining supply partner like T3 can reduce expense, streamline efficiency, and provide consistent training for every member of their teams.

Why Is It Important to Fix Root Intrusions in Sewer Pipes?

Root intrusions in sewer pipes can cause many problems, both minor and major, for homeowners and their property. It’s especially common for sewer lines made of terra cotta or clay, but root intrusions can also occur with rusted cast iron sewer pipes and damaged PVC lines.

When plant roots break into sewer lines, the wastewater inside can leak into the ground around it. Early on, that leaking can contaminate the soil and cause environmental issues. But if it isn’t repaired quickly, root intrusion can lead to soft, muddy soil along and around the sewer line. That wastewater can also cause foul smells and damage to concrete, landscaping, and hardscaping. Homeowners in need of sewer pipe repairs want a fast and effective solution to keep their property safe.

Temporary Solutions for Root Intrusions

Homeowners are often looking for inexpensive or do-it-yourself alternatives to calling a plumbing or pipe repair company. Some temporary solutions could save some money upfront, although a professional may still be required for more severe issues.

Methods

Chemical Removal: The most common temporary solutions to root intrusion issues generally employ chemicals to kill and dissolve the roots in the sewer pipe. These root-killing chemicals can include rock salt, foaming root killers, and copper sulfate.

Mechanical Removal: It’s also possible to remove tree roots mechanically. Water jets and cutting heads can eliminate existing obstructions quickly, and in most cases, they’re safe for pipes.

Pros

These cleaning methods usually offer homeowners low-cost solutions to root intrusions, so long as the pipes are structurally sound. And the use of chemical root killers can be a DIY option so a homeowner can address the problem without a contractor.

Cons

While temporary solutions can offer a simple and cost-effective alternative to major repairs, both mechanical and chemical removal of the roots will need to be repeated regularly (likely once a year or so). These options simply don’t address the primary cause of the sewer line damage. And when you remove tree roots in sewer pipes with chemicals, the process is often a guessing game as to how effective it will be long-term

Permanent Solutions for Root Intrusions

On the other hand, homeowners may want (or need) a more permanent solution to their root intrusion woes. These longer-lasting methods allow homeowners to fix root intrusions in sewer pipes only once, rather than once a year.

Methods

Permanent sewer lateral root removal options like pipe bursting, slip lining, and even full trenching and replacement aim at solving the problem at the source: the roots. In each case, the host pipe isn’t just cleaned out. Instead, it’s either reinforced or replaced.

Along with addressing the intrusions in the pipe, it may be necessary to remove the plants that caused the root intrusions. This removal better ensures that the sewer pipe won’t be damaged again.

Pros

The most important advantage of choosing a permanent fix for root intrusions is that it will only need to be performed once. In many cases, the repair could last as long as 50 years.

Cons

These permanent solutions are often more expensive than temporary fixes like root killers or drain cleaning. But they can also cause damage to landscaping and concrete above and adjacent to the sewer line. Pipe bursting can also compromise grade, which could cause damage to larger structures like patios.

Why Use CIPP Lining to Fix Root Intrusions in Sewer Pipes?

There is a solution that offers both a fast and effective way to fix root intrusions in sewer pipes: CIPP lining. This trenchless repair method offers long-term benefits without the drawbacks of other temporary or permanent solutions. Plus, there are few exceptions to what can be repaired.

What Is CIPP Lining?

Cured-in-Place Pipe (CIPP) lining is a pipe repair technique where a felt or fiberglass liner is inserted into a damaged host pipe and then cured inside the pipe using heat, steam, or UV light. Most repairs take less than 4 hours to complete, and CIPP provides a completely new and structurally functional “pipe within a pipe” without digging and trenching.

Benefits

  • Cost-Effective: CIPP is less expensive than trenching, and the one-time repair eliminates years of expense for DIY and temporary fixes.

  • Less Damage: With little to no digging, lawns, sidewalks, and driveways stay intact.

  • Fast Repairs: Today’s CIPP technology can cut repair timeframes down to hours instead of days or weeks.

  • Long-Lasting: The cured epoxy resin is as hard as PVC pipe, so it keeps tree roots from breaking into the sewer line in the future. And CIPP repairs can last 50 years or more.

  • Reliable: CCTV inspections before and after CIPP installations make it possible to be confident that sewer lines are repaired correctly, making it a more reliable option for both homeowners and pipe repair businesses.

Exceptions

  • Bellies: If the pipe has a belly, CIPP liners can’t bond properly to the walls.

  • Collapses: Pipe liners need to be pushed through the pipe lines, so if a pipe has collapsed underground, you’ll need a different approach.

  • Serious Structural Damage: Pipes must be strong enough to handle the pressure of the liner during the curing process without bursting.

  • Shifting: In seismically active areas, a visual inspection could show that clay pipe sections have pulled apart. In some cases, CIPP may still work, but in most cases, these shifts make it difficult for the liner to be inserted properly.
