Pipe Bursting versus Pipe Relining: A Brief Comparison

Providing long-lasting, quality underground sewer repairs for our customers is the cornerstone of our industry. There are several methods for performing these repairs, which range from tried and true to new and innovative. Two procedures our company utilizes most often are pipe bursting and pipe relining.

Sewer Line Repair Options

Before considering purchasing equipment to perform either type of sewer line repair, check with local inspectors regarding what types of repairs are approved for use. It is possible to convince local inspectors to consider approving new methods. Being a pioneer with a relatively unknown method in your area would give you an advantage in the marketplace. Always take the opportunity to be a leader!

Pipe Bursting Technique

Mr. Rooter Plumbing of Buncombe and Henderson Counties took a leap of faith in facilitating the education of local inspectors about pipe bursting in 2006. We saw the advantages and approved it for use to repair spot breaks in sewer lines using high-density polyethylene (HDPE). When the pipe bursting method is used, the end result is a brand-new HDPE pipe with fusion welded joints. The overall investment to start in pipe bursting is lower than it would be with relining. The material cost for each job is lower. This means the overall job price is less for our customers. If the pipe has lost its integrity (become oval-shaped or crushed), pipe bursting is the only method (of the two methods discussed in this article) that can be pursued. Some drawbacks of this procedure are that two access holes are required, and it cannot be used under buildings. If there are branches entering the line, each area must be exposed; the branches must be disconnected and then reconnected after the burst is complete. Any information about these procedures has the potential to be area-specific. The wisest approach to take would be to seek information from local municipalities regarding regulations.

Pipe Relining Technique

In the winter of 2014, our company decided to invest in relining equipment. We had some experience with the process, as we had subcontracted (to vendors who traveled great distances to bring this service) for relining on past jobs. A project had been presented for which relining was the only option, and we took this as a sign that it was time for our company to step forward as the innovator in our area. Our relining equipment type uses an inversion drum and hot water cure system. There are choices to be made when purchasing a system; each option has correlating price and time considerations. Relining can be tricky, so time and opportunity for training are a must. The procedure requires at least two people with ample skill. Relining is not a viable path to repair crushed pipes. The materials can be costly. While it seems daunting, the opportunity to provide an area with relining as an option for sewer line repair should be seriously considered. Laterals can be reinstated without exposing the line. Not many contractors can perform relining. It is a very versatile repair method with fewer access requirements, which is beneficial for jobs involving large concrete areas and intricately manicured landscaping.

When it comes to sewer line repair, there is no “always the best” option. Neither of these methods will remove a belly in the line. Research each available technique and choose what is right for your business in order to meet the needs of your community.
