Continued Cleaning, Excavate, Burst or CIPP Repair For A Pipe Defect

Best Practices – 3rd in the series –

The challenge of pipe defects outside the building usually end with roots growing into the sewer line through missing sections of pipe, joints, taps, and worn away pipe inverts. Moving outside the house gives us a lot of options for pipe repair.

  1. We have digging the entire length of compromised pipe and replacing it with new pipe.
  2. Pipe bursting gives us the options of opening two pits to install a new pipe by bursting the existing pipe ahead of pulling in a new pipe through the same alignment as the old pipe.
  3. The third option involves the CIPP process where we impregnate a fabric tube with resin, install it through a clean out or other opening and stop it before the main giving a complete “no dig” option to pipe rehabilitation.

These processes differ in this respect. Excavation or bursting will not require any pipe cleaning or preparation before executing those options. This leaves us with pipe cleaning for the CIPP rehab option. Here’s where you need to weigh options for your customer.

  • What are the impacts of excavating in terms of disruption and costs?
  • What are the impacts of pipe bursting regarding pit locations and how the pipe orientation is set?
  • Will I need multiple pits to accommodate direction changes of pipe?
  • Will I need a pit in the street at the sewer main?
  • If I choose the CIPP option, do I have any excavations to make or can I line through the clean-out?
  • How much cleaning of the host pipe will be needed to accomplish this job?
  • Are there any collapsed sections of pipe I’ll need to repair before lining?
  • For all options, will I need permits?
  • What restoration will I need to complete to put everything back to the way it was before I started?
  • Will I be able to complete the work and let the building be occupied while the job is going on?

The best practice here is to discuss all of these impacts and costs with your customer in advance, so they aren’t surprised by a forgotten cost here or a night or two in a hotel while completing your work.

We have 3 options for replacing the pipe when moving outside the home. You may select one option over the others when you calculate the impacts of each or you may find you use two or three of the options because that path appears to be the best path. Each option represents a tool in your tool box and you select the right tool to complete your work. All 3 of these options have many articles published regarding “best practices” for the work and we won’t rehash previously published and accepted industry standards. You can find them online through your favorite search engine.

Further, your suppliers will provide you the best practices for using their technologies as we have with our published “Step by Step” installation methods that pertain to the materials we supply. Our goal here is to give you best practices of managing your work and not necessarily executing your work. For more information call us at +1-888-354-6464 or write to
