What Is Trenchless Pipe Replacement?

It’s hard to describe any plumbing repair as good. Most homeowners just put them on a scale from bad to worst. Sewer line repairs are usually towards the “worst” end of the spectrum. When sewer lines have problems, nasty sewage can return to homes in the worst-case scenarios. In minor cases, none of the toilets will flush, nor will the basins and tubs drain water. 

Up until recently, sewer line repairs meant very invasive repair strategies. Since sewer lines are beneath the home and the surrounding grade, sewer lines had to be dug up to be replaced or repaired. Recognizing the pitfalls (pun intended) of traditional sewer repair, plumbers set out to find a better way. Trenchless sewer line repair is the answer. 

Here are some of the most common questions about trenchless sewer line replacement with answers from local experts. 

How Does Trenchless Sewer Repair Work?pipe

Instead of using trenching machines and backhoes to dig deep and wide swathes to accommodate new sewer piping, trenchless methods expose the sewer line in two places, at either end of the pipe to be replaced. Using special machines, heavy-duty cables are passed through the old line. From there, there are three options to repair old pipes: 
  1. Slip Lining: During slip lining, the cable inside the sewer line is attached to a new slightly smaller, flexible pipe. The cable is then winched back through the old pipe leaving a new lining inside the old pipe. 
  2. Pipe Bursting: Instead of lining the old pipe with a new liner, pipe bursting uses a powerful hydraulic head to destroy the old pipe while simultaneously pulling a new one through the old pipe’s path. 
  3. Cured-in Place Pipe (CIPP): CIPP is similar to slip lining in that it uses the old pipe for support. However, with CIPP a flexible sleeve is pulled into the old pipe and then exposed to an agent that causes it to cure in place. This leaves a new pipe in its place. 

What Issues Can Trenchless Pipe Repair Help With? 

Trenchless pipe repair is a tremendously useful procedure for homes suffering from chronic sewer problems. Chronic sewer problems are always an indication that something bigger is going on. Some of the underlying causes of sewer problems that trenchless pipe repair can fix are: 

  • Sewer backups
  • Tree root infiltration
  • Sewage leaks
  • Cracked clay or iron pipes
  • Corrosion that causes blockages
  • Minor sewer lines are misaligned due to shifting over time. 

save Why Is Trenchless Pipe Replacement the Best Option? 

Sewer line replacement is one of the most invasive home repairs that one can do. Historically it always involved digging huge trenches in the yard and most often required jackhammering of foundations or digging through basement walls. In the process, sidewalks and landscaping would have to be removed, and it would take years for things to look beautiful again. With trenchless sewer repair, homeowners can skip the hassle. 

In addition to being less invasive, trenchless sewer repair is quicker. Because crews don’t have to carefully dig through an entire property, the repairs can be done much quicker and more precisely. And since time is money, trenchless pipe repairs can also be cheaper than traditional repairs.
