What Is the Process for Trenchless Sewer Line Repair?

Do you frequently need to have your sewage lines repaired or have you been informed that they are partially collapsed and infested with roots? If so, a typical sewage line replacement or a trenchless sewer line repair may have been suggested by your neighborhood plumber.

Plumbers must dig a sizable trench in your yard to do a standard trenched sewer repair. In order to remove the broken sewage line and install a new one, they must cut through your well-kept grass and lovely landscaping. Trenched sewer repair is not only ugly and unsightly, but it may also seriously harm the root systems of trees in your yard, killing the trees and drastically changing the landscape you’ve worked so hard and spent so much money to create.

An approach that prevents your yard from being covered in mounds of dirt and preserves your landscape is trenchless sewer repair, often known as pipe bursting. Where the sewage exits the house in the basement, the plumber tears up a tiny portion of the floor. At the opposite end of your yard, where the sewer starts, another hole is excavated. The plumbers then insert an elevator cable through the preexisting sewage line after gaining access to the sewer at both ends. They connect your new sewage line, which is made of high-density polyethylen and installed on-site in your yard, to one end of the cable.

Replacement of Traditional Sewer Lines

The majority of residential and commercial property owners picture wide ditches, enormous gear, and devastated hardscaping and landscaping when they consider repairing a sewage line. This is so that a new pipe may be installed instead of the old one, which requires excavating a trench along the whole length of the sewage line that has to be replaced. This approach is frequently chosen by property owners because it provides them piece of mind knowing that the pipe can be visually inspected to confirm that the installation went smoothly and that the new pipe is in the right location once it has been replaced.

This may be the best option for certain property owners who have a blocked, leaky, partly or entirely collapsed sewage line. However, owing to the additional expenditures for landscaping, concrete or asphalt replacement and maintenance, it might not be the most economical choice if the sewer line runs beneath parking lots and walkways.

In certain situations, a trenchless sewer repair may be a better option than a conventional sewer line replacement.

Trenchless sewer line repair techniques

Trenchless pipe repairs come in three main categories, including:

  • drilling with direction
  • a pipe bursts
  • lining for trenchless pipes

Your method of choice will be influenced by your financial situation, the state of your pipes, and your plumber.

Drilling in a Direction

A method of pipe replacement known as directional drilling entails excavating a new sewer pipe tunnel several feet below the pre-existing sewer line.

This approach is usually used when extenuating conditions make replacing or repairing the current sewage line excessively challenging, costly, or time-consuming.

A horizontal drilling equipment used for directional drilling is typically little larger than a small excavator or golf cart. Before drilling horizontally throughout the whole length of the pipe that has to be replaced, the drilling machine first penetrates the earth to a specific depth. The new pipe is placed and joined to the old pipe network after the dirt and debris are cleared out of the tunnel.

A pipe bursts

Pipe bursting is the process of using a bursting head to split or rupture the original sewage pipe.

In order to reach the existing sewage line, two tiny access holes are dug at the start and end of the pipe run for this trenchless sewer line repair method.

The current pipe line is then forced through the bursting head. The old sewage pipe is split apart as the bursting head advances, pushing the pieces out of the path while simultaneously drawing the new pipe into position.

pipeline trenchless lining

A relatively recent technique for repairing subterranean sewage systems is trenchless pipe lining.

Professional plumbers with trenchless pipe lining certifications and pipe lining training perform this procedure.

The fact that trenchless pipe lining may frequently be completed with little to no digging is its biggest advantage. The procedure is inserting a felt or fiberglass pipe liner through an existing sewage pipe after soaking it in epoxy glue. The liner is then compressed against the host pipe and inflated.

After installation, it is given four to twenty-four hours to cure. It is effectively a pipe inside a pipe, and this trenchless pipe repair method is also known as CIPP (Cured-In-Place-Pipe).

Trenchless sewer line repair advantages

Compared to regular sewage line replacement, trenchless sewer line repair has numerous advantages.

The main advantage is that very little excavation is required, which means that roads, sidewalks, yards, and landscaping do not need to be destroyed in order to access the leaky sewer line.

The following are other advantages of trenchless sewage line repair:

  • a quicker repair process that typically takes one to two days to finish
  • cheaper than replacing a typical sewage line
  • No need to fill up deep ditches; little to no harm to the hard-scaping and landscaping

Choosing between trenchless sewer line repair and traditional pipe replacement

  • Trenchless pipe repair and conventional pipe repair may seem like difficult tradeoffs to make, but our expert plumbers in Richmond and Charlottesville can advise you on which is ideal for your residence or place of business.
  • Generally speaking, if the sewer pipe doesn’t pass beneath any outbuildings, walkways, roads, or parking lots and you don’t mind having your landscaping destroyed by deep holes, you might choose to pick a standard sewer pipe replacement.
  • Depending on how your drain and sewage line system is set up, a typical replacement may also occasionally be more affordable.
  • Trenchless sewer line repair is typically chosen when the traditional replacement’s costs are higher than the trenchless alternative, including restoring the landscape and repaving a portion of the driveway or parking lot.
  • Trenchless sewer line repair is preferred by homeowners and business owners who cannot afford to have their plumbing system out of commission for an extended period of time. Additionally, it is the best option for those who want a green alternative that offers the same lifespan as a conventional sewer line replacement.

In conclusion, the trenchless sewer line repair sees like the most convenient due to its numerous advantages compared to the traditional sewer repair.
