What Is Trenchless Sewer Line Replacement

Definition of Trenchless Sewer Replacement

Trenchless sewer replacement is a relatively new repair method that removes the need for extensive excavation. Rather than tearing up large portions of the lawn or pavement, trenchless technologies utilize a combination of lateral pipe bursting and relining materials to replace or restore buried pipelines.

This process usually employs trenchless technology, which includes pipe liners and resins. These materials are fed into the existing pipe to form a new, tough liner or interior. Additionally, the new liner will last 40-50 years, providing a long-term solution.

This approach is focused on fixing the sewer system at a reasonable cost. At the same time, it saves landscaping, sidewalks, and driveways from needless destruction.

How Trenchless Methods Differ from Traditional Methods

In contrast with conventional sewer replacements, trenchless repairs sidestep the burdens of digging big trenches. This greatly minimizes the damage to landscaping, decks, or driveways.

Repair is done in one or two days as opposed to weeks using traditional techniques. For instance, pipe lining can repair an entire sewer line in less than a day with only a few access points.

Not only are these methods less invasive, they can be more economical, saving taxpayers up to 50% on project costs. Since trenchless repairs alleviate the need for excessive physical labor and subsequent restoration, time and money are saved on both ends of the process.

Common Trenchless Sewer Line Replacement Methods

Trenchless sewer line replacement provides creative options for replacing damaged sewer lines with less hassle and inconvenience. With an approach that’s customized to each specific damage, these methods deliver proven, effective, long-lasting results. Choosing the best method for replacement will vary based on the condition of the sewer line, since every technique has distinct advantages.

Developments in trenchless technology have made these techniques faster, more accurate and safer than ever before. In the process, they have become more affordable and predictable.

1. Pipe Bursting Method

Pipe bursting is a trenchless sewer repair method that involves breaking the existing pipe while simultaneously replacing it with a new one. A pulling head breaks the old pipe as it drags a new high-density polyethylene (HDPE) pipe into the old pipe’s place. This trenchless option only requires a minor entry and exit pit, making it ideal for flat, horizontal sewer lines.

The entire trenchless sewer line replacement process is completed quickly—usually within one to two days. As a result, you end up with a strong, resilient system that can last upwards of half a century. In a residential setting, this technique minimizes disruption while addressing plumbing problems, such as replacing an aging or damaged 4-inch sewer line.

It effortlessly passes below an active driveway without needing to disrupt the concrete.

2. Pipe Lining Method

The pipe lining method, particularly the type known as cured-in-place pipe (CIPP) lining, consists of inserting a resin-coated liner into the damaged pipe. Once in place, the liner is cured, creating a strong, seamless new pipe within the old one. This technique needs extensive inspection and cleaning for the new liner to bond correctly.

It’s best suited for sealing cracks or leaks in current pipes from the inside out with no digging required. A home with a degraded 6” sewer line can get up and running in no time. All of that in as little as a few days if they use CIPP!

3. Horizontal Directional Drilling Method

Horizontal directional drilling (HDD) is another trenchless method used to install new pipes underground with high precision and low surface disruption. This is a highly effective trenchless technique for crossings under challenges such as roads, sidewalks, or landscaped areas.

HDD is adaptable, operating efficiently in differing soil types and working for both residential and commercial projects. For instance, yes, a company can replace a 12-inch sewer line underneath a congested street by going this route.

This allows them to continue business as usual, even under the need for a lot of digging.

4. Spray-In-Place Pipe Lining Method

Spray-in-place pipe lining consists of spraying an epoxy or polymer coating directly into an existing pipe. This method is non-structural and is ideal for smaller diameter pipes, like those found in residential plumbing systems. The installation process is quite simple, and provides a fairly quick turnaround time with little to no disruption to your property.

A homeowner with a decrepit 3-inch pipe in their basement can replace it in a few hours. This method allows for fast, trenchless, and permanent repairs!

Purchasing specialized tools and materials is a must for trenchless methods. Consequently, these methods typically incur greater up-front expenses than conventional trenching. Resins Cured-in-place pipe (CIPP) processes use CIPP epoxy resins that contain bisphenol A (BPA) and formaldehyde. Depending on the exact materials used, these can take multiple hours up to a day to fully cure.

The upfront cost can seem daunting at first. You will find major long-term savings from reduced labor and restoration costs, which more than offset it. For most, this trade-off is well worth the investment in order to skip potentially costly landscaping repairs. If you look only at the upfront cost, you won’t see the larger value. Taking this narrow view might keep you from identifying a more effective solution.

Limited suitability for certain soil types

Soil composition plays a crucial role in determining the feasibility of trenchless repairs. In rocky terrains or highly unstable soils, these methods might face significant challenges. Techniques like pipe bursting, which require pushing materials through the ground, often struggle in such conditions.

CIPP has specific pipe requirements, performing best on straight pipes between 1.5 to 6 inches in diameter and over 15 feet long. Pipes with multiple bends or diameters under 2 inches may not be ideal candidates, limiting the scope of this method. A thorough evaluation of the ground and pipe conditions is vital to ensure success.

Requires specialized equipment and expertise

It is essential to recognize that executing trenchless sewer line repair requires specialized equipment and trained professionals. Hydraulic machines and resin application systems are key tools in trenchless sewer repair methods to maximize effectiveness and efficiency. Misuse can lead to inefficient use or even damage that complicates sewer line issues.

Trenchless sewer repair usually runs from $80 to $250 per foot upfront. It usually ends up saving you money over time.

With trenchless technology, durable materials are used, such as pipes made from PVC, clay, or cast iron, which can last 50 years or longer. This durability decreases the frequency of repairs, saving on maintenance expenses.

The speedy execution reduces disruption to everyday activities, providing both economic and convenience advantages.

Comparison Between Trenchless and Traditional Methods

Differences in Installation Process

Trenchless methods employ cutting-edge technologies like pipe lining and pipe bursting. These techniques greatly minimize the disruption caused by large-scale digging.

Pipe lining consists of inserting a flexible tube coated with resin into the damaged pipe. Once the resin is cured, it forms a strong new lining.

With pipe bursting, the old pipe is replaced by pulling a new one through. It very effectively breaks apart the existing pipe in the process.

These processes are quick, sometimes taking only hours or days to complete, minimizing the inconvenience of downtime for homes and businesses.

In contrast, traditional methods require workers to do a lot of digging to access the old pipe. This highly labor-intensive process often takes several days, even weeks, to accomplish. It comes down to how bad the pipe is damaged and how long of a stretch needs to be replaced.

Cost Comparison Over Time

In contrast, trenchless methods typically range in cost from $80 to $250 per foot of pipe. Though this seems steep, traditional methods average between $50 and $250 per foot as well.

In many instances, trenchless techniques are actually more economical in the long run. They take less labor hours and circumvent the extra costs of replacing or repairing landscaping or other infrastructure.

In fact, research maintains that trenchless techniques represent a more cost-effective alternative 80% of the time, particularly when it comes to complicated repairs.

Impact on Landscaping and Infrastructure

The most significant benefit of trenchless repair is the reduced impact on landscaping and infrastructure. These techniques preserve existing driveways, sidewalks and yards from unnecessary destruction.
