Is a Trenchless Sewer Line Right for Your Septic Repair?

If you have a broken sewer line in your septic system, you may be wondering if a trenchless sewer line repair is a good option. No one relishes the thought of tearing up their yard to replace sewer lines, which is why trenchless pipe repairs can sound like a good option. However, there are some factors to consider before you choose a trenchless sewer line versus traditional pipe replacement.

Trenchless sewer line repairs are attractive to homeowners. They do not require the broken pipe be dug up with a trench. Instead, a pipe lining or soft-lined pipe is put in place of the broken pipe. This only involves digging two holes on either side of the broken pipe instead of a trench. This can save landscaping and take less time. However, there are some drawbacks to this method. Some factors that can be a problem include:

  • The grade or slope of the pipe needs to be just right. Pipe lining or trenchless pipe replacements require the right slope or pitch to work correctly.
  • Pipe bursting can cause disruption and damage to other structures underground. Pipe bursting is used when the pipe is being replaced using a trenchless method; if underground utilities are too close, the bursting action could cause damage to this equipment.
  • Unforeseen complications can result in a trench method to be needed, causing further delay and cost.

While trenchless pipe replacement or repair can be beneficial in some situations, it is not the solution for all sewer pipe repairs. Traditional sewer line repairs may require a trench, but many issues can be avoided with this method. Talk to your local sewer/septic repair services about which method is best for your sewer line repair.

Why Use Trenchless Sewer Line Replacement?

Simple, because now you can! In times past, existing pipe repair or replacement meant that the ground burying those pipes must be removed. Traditional methods required deep excavation and the digging of trenches, potentially damaging lots of ground and landscaping, oblivious to their aesthetic appeal. Today’s trenchless sewer line replacement techniques have practically eliminated such distasteful consequences. It is now possible to replace existing water and sewer lines completely underground.,

Traditional trench digging and pipe excavation caused an enormous amount of disruption, of land and quiet. Where the pipe lays, under what road or building, is no longer an issue, as with trenchless pipe replacement there is no more land disruption. Additionally, this new hydraulic pipe laying method is quieter and smoother, no longer consisting of threatening noise levels or jarring vibrations. Furthermore, by accomplishing the replacing of sewer pipes entirely underground, a enormous saving in labor and equipment time is recognized (breaking apart the ground, digging a trench, refilling the trench, etc.). Of course, we all know that “saving time, saves money!” By saving time, labor and equipment, trenchless sewer line replacement can be performed at much less cost.

Another advantage of the trenchless sewer replacement technology is the potential for reduced delays. In the past, encountering the unknown in existing cables or pipes has necessitated additional trenching, causing further damage to ground surfaces, time, and cost. By using sensors, this technology can quickly identify the potential hazard of interfering objects, enabling adjustments and rerouting of the pipe, so that work may be continued safely with little interruption.

It certainly seems that the overall benefits of today’s trenchless pipe replacement system warrants a call to your local plumbing or sewer replacement professional for further consideration.

 

No-Dig Sewer Line Repair

Damaged or broken plumbing can be a major or a minor headache, depending on the nature of your particular problem. Sometimes the source of the trouble is easy to find and sometimes you think you might as well just put in an entirely new system. Before you decide to just chuck it all and call in the backhoes and dozers, there are a few things to try.

One method of pipe repair is known as trenchless piping repair. Trenchless repair is an accepted method of repair and replacement that has come into vogue in recent years. Now, there is some digging involved, but it is minimal compared to other fixes. Entire sections of pipe don’t always need to be pulled and replaced when you go with trenchless work. Instead, once the trouble spot is pin-pointed, an epoxy is injected, which forms a mold and a type of pipe-in-pipe solution. If the break is located near a clean-out very little excavation may be involved because the epoxy can be poured through the cleanout itself.

The epoxy is strong but relatively thin so that flow is not significantly reduced, and in some cases can be injected so as to increase the pipe size. Most homeowners won’t have the equipment or technical proficiency to do this kind of work and will need to hire a pro. But, with much less disruption to the ground and little excavating, the cost effectiveness can make this a good option. Your sewer professional will be able to tell you if trenchless work is feasible or advised. And, as always, you’ll want to make sure your sewer professional is properly certified and that all work meets local codes and requirements.

Trenchless Sewer Line Repair

No one wants to have to undergo a sewer line repair or replacement. For one thing, they can be costly, up to $20,000 depending on the nature and extent of the problem. For another, they are very disruptive, especially when a backhoe has to be taken to the whole back yard to get to the target pipes, which can lie under the garage, patio or new lawn you just installed.

Well, at least now there is relief on one front. Sewer septic companies have begun offering trenchless sewer line repair, a process which involves very little digging, if any.

How does it work?  Basically, the sewer septic professional will go through one or two entry points with a long narrow probe and fix the damaged pipe using one of two techniques:

Pipe Lining – In this type of repair, a flexible tube coated with resin is pulled through the damage pipe and then inflated. The resin then hardens to form a new tube inside the pipe, diminishing its diameter by a mere quarter inch.

Pipe Bursting – In this type of trenchless repair, a new pipe is drawn through the old one, bursting it in the process. With this method, there is no reduction in the diameter of the sewer line.

Both of the above methods are more costly than traditional sewer line repair or replacement, costing between three thousand and twenty thousand dollars per pipe section.  However, if it means that you do not have to dig up the driveway, garage or entire lawn, it might well be worth it. The only way to know for sure if this option works for you is to contact your local septic sewer contractor for a consultation.

Sewer Line Repair Methods

Your sewer lines carry wastewater, including untreated sewage, from your home to the municipal sewer.   A broken sewer line provides an avenue for this wastewater to seep to the surface.  In addition, it can seep deep into the soil and contaminate the groundwater.  In either event, it poses a health hazard and potentially expose you to legal liability.

If you suspect a broken or leaking sewer line, have it checked out by a sewer septic professional today.  This is not a problem that the homeowner can handle themselves.  Sewer line repairs require special equipment and expertise and are best handled by a professional with experience in sewer line repair services.

If your sewer line is broken, there are a couple different types of repairs to consider.  The traditional method involves digging up the old line using a backhoe, then replacing the damaged section or the entire line if necessary.  This method really tears up your yard, shrubs, driveways, patios, and sidewalks.

There are “trenchless” methods that involve less digging.  In one such method, a section of flexible pipe is dragged through the area where the old pipe was laid.  The old pipe is destroyed and the pieces are removed in the process.  This method has the advantage of requiring less digging.   Usually, only two medium sized holes are needed, one at each end of the pipe section to be replaced.  One potential downside is that this method is not allowed by some local building codes.

In the other trenchless method, a coating is sprayed on the inside of the old pipe creating a new pipe “liner” like the inside of some tin cans.  This method minimizes the necessary digging, but it is only effective on pipes that are essentially structurally sound but have a few cracks.
