Trenchless Sewer Repair vs Traditional

Many people hear the word “trenchless” sewer repair and they think it is a special type of sewer. Actually the word trenchless only applies to a new method that is used to repair or replace a traditional sewer. It is called trenchless because the sewer pipe is repaired without having to dig a trench as is the case with traditional sewer pipe replacement.

Traditional sewer repair requires bringing in a backhoe and digging up the old sewer pipe, replacing it, and then filling the trench back in. This is troublesome and costly for people that have nice lanscaping, driveways or trees that the pipe runs under that will need to be removed. The good news is this is no longer necessary with the advent of trenchless sewer repair.

Lets Compare Tradtional Sewer Repair vs Trenchless

Traditional Sewer Repair

  • Requires Extensive Excavation
  • May Require Removal of Porches, Trees, Driveways, Etc
  • Average Length of Project Can Be 3-5 Days
  • Softer Soil Substrates May Cause New Pipe To Sag During Settling
  • Regrowth of Lawn and Landscaping Can Take Several Weeks
  • New Pipe May Have Several Joints Prone To Root Intrusion

  • Now this not to say that traditonal sewer repair should be avoided, in some cases it is the only solution depending on the severity of damage to the existing sewer pipe and the path of the existing sewer pipe. If the old pipe has completely collapsed or has a major belly from settling then trenchless sewer repair will not work in these cases. We will cover why a little later in this article.

    Trenchless Sewer Repair

  • Requires Little Or No Excavation
  • Does NOT Require Removal of Porches, Trees, Driveways, Etc
  • Average Length of Project Is Less Than 1 Day
  • New Pipe Follows Path Of Existing So No Risk of Settling
  • Regrowth of Lawn and Landscaping Not Required (not disturbed)
  • New Pipe Will Be Seamless, No Joints For Roots To Penetrate

  • So you can see trenchless sewer repair is an awesome technology that under the right circumstances is far superior to traditional sewer repair in many areas like minimal disturbance to yard and structures, completed quickly, seamless pipe will lock out roots for good. So what are poor circumstances for trenchless option? Let’s list them out

    Poor Candidates For Trenchless Sewer Repair Option

  • Existing Pipe Has Major Sagging Issues
  • With trenchless the new pipe will follow the path of the existing pipe so if it has a major sag, so will the new trenchless pipe

  • Existing Sewer Pipe Is Severely Crushed or Collapsed
  • For trenchless sewer repair, the existing pipe needs to have a least a fair amout of structural integrity to give the new trenchless liner a decent path to follow, however cracks and breaks are not an issue, a new trenchless liner will seal cracks and bridge breaks easily, even major breaks.

    So if your existing sewer pipe isn’t severly crushed or doesnt have a major sag then you would be a gret candidate for trenchless sewer repair. The type of pipe doesnt matter, it can be orangburg, cast iron, concrete, or even tar paper that was used many years back in several parts of the United States, the trenchless method works pefectly on all types of sewer pipes.
