Pipe Bursting versus Pipe Relining: A Brief Comparison

By Adam Glovan, of Mr. Rooter® Plumbing of Buncombe & Henderson Counties, NC

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.

When the pipe bursting method is used, the end result is brand new HDPE pipe (an environmentally sustainable, non-toxic, corrosion and chemical resistant pipe) with fusion-welded joints. The material cost for each job is lower, which 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 blog) which can be pursued. Some draw backs 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.

Relining can be tricky, so time and opportunity for training are a must- something that Mr. Rooter has. Relining is not a viable path to repair crushed pipe, and the materials can be costly. Laterals can be reinstated without exposing the line. Few contractors have the ability to perform relining. It is a very versatile repair method with less access requirements, which is very 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 consult with your local plumber when pipe problems arise.
