Top 5 Things You Need to Know About Trenchless Sewer Replacement

Fortunately, there are many ways to do this without digging trenches. One method is called trenchless pipe lining.

This process involves pulling an epoxy liner through your existing pipe.

Less Disruptive

Sewer line breaks or blockages are among the most unpleasant plumbing problems you could face as a homeowner. Thankfully, modern sewer repair technology has dramatically reduced what used to be a six to eight-week process into a one-day solution with minimal disruption to your home and yard.

With trenchless sewer replacement techniques, there’s no need to dig huge holes around the old pipe to replace it. Instead, pipe bursting is used to break up the old pipes while a new HDPE (high-density polyethylene) pipe is pulled behind.

This method uses a cylinder-shaped head, known as a "bursting bullet," to burst apart the existing pipes while pushing them away and replacing them with the new pipe. It also requires two access holes for the new pipe’s entry and exit points.

Another trenchless method for repairing your sewer lines is pipelining. This uses a flexible pipe coated with resin to create a "pipe within a pipe" solution.

The new lining can repair damage to the old pipes in just a few hours, while saving you the cost of bringing your landscaping back up to its original state after excavation with traditional repair methods.

Less Invasive

It can be a considerable stressor when a homeowner is told they must have their sewer line repaired or replaced. Traditionally, sewer repair requires digging large trenches to locate and access the broken pipe.

This method is expensive, time-consuming, and causes damage to lawns, driveways, and sidewalks that must be restored. The main advantage of trenchless repairs is that they don’t require digging.

In this process, an inflatable tube is inserted into the existing line and then blown with a high-pressure pump. This forces the liner to fill up and cover the entire inside of the broken pipe, forming a new water-tight seal.

There are several other benefits to trenchless repair as well. This method allows us to reach difficult-to-reach locations, like those under driveways, patios, and sidewalks.

It also means that your landscaping and lawn design remain intact. Because trenchless repair doesn’t cause collateral damage, it can be completed in as little as a day and costs significantly less than the dig-method option.

Less Expensive

Traditional sewer line repair is expensive because plumbers need to dig and repair large sections of your yard. Trenchless methods like pipe lining and pipe bursting can cost less because they don’t require extensive digging or landscape restoration.

The length of the pipe and the type of pipe also affect the cost. Longer pipes need more pipe material and are more expensive to install than shorter pipes.

Pipe materials like copper and cast iron can be more expensive than PVC or ABS. Depending on where the pipe is located, it may cost more to use trenchless methods than to dig a long trench across your property.

This is especially true if the line runs under sidewalks, driveways, or parking lots. The best way to reduce costs is by working with a plumbing company offering trenchless repairs. This allows you to save money on the initial cost of excavation and landscaping restoration while getting high-quality, long-lasting results at affordable rates.

For example, if tree roots damage your sewer line, you can have the problem repaired using the trenchless pipe lining method. This only requires a small access hole to get inside the old pipe and a flexible pipe coated with resin blown or pulled through the old pipe to re-line it.

Longer Lasting

Traditionally, when you had issues with your sewer line, plumbers would dig up your yard to repair or replace the damaged pipe. This could take weeks and leave your property looking destroyed.

Trenchless technology has reduced this to a one-day process that is less disruptive to your everyday life. Trenchless methods also are longer lasting than traditional ones.

This is because the new pipes are subject to different wear and tear over time, and your landscaping will grow back faster after the excavation is completed.

Moreover, trenchless methods like pipe bursting slip lining are more effective than traditional repairs. Pipe bursting involves pulling a "bursting head" through the old pipe, which breaks it apart and pulls a new high-density polyethylene (HDPE) pipe into its place.

Alternatively, slip lining installs an epoxy liner over the existing pipe and essentially creates a pipe within a pipe. The liners are razor-thin, but they still have enough room to prevent future blockages.

Both methods require only one access point and can be performed through clean-out caps, roof vent openings, or other accessible areas on your property.

Less Time Consuming

Traditionally, when homeowners replace or repair their sewer lines, the plumbers must dig long trenches down the line. This can disrupt your yard and take a lot of time and money to fill back in the dirt that was taken out.

With trenchless technology, however, your landscaping and lawn design is kept intact and does not need to be rebuilt. In addition, because trenchless repairs help your pipes function better, they reduce the need for future maintenance and replacement.

This is because the liners can increase flow capacity, and new pipes installed using trenchless methods can be larger than the previous ones. Ultimately, your new piping is more durable, reducing future leaks and failures.

This can save you a lot of money in the future.
