Trenchless Drain Repair: Everything You Need To Know About Stress-Free Drain Repair Techniques


Trenchless Drain Repair

Sewer line issues are inevitable and can happen when you least expect them. The repair process can also be tedious and costly without the most suitable method. A typical drain relining cost can be upwards of $4,000 to $13,000 if you use outdated traditional drain repair techniques.

On the contrary, the new technology-driven trenchless drain repair method is cheaper, with some costing from $6,000 but not beyond $12,000. Trenchless is also less time-consuming and less disruptive to your property. This article explains a wide range of trenchless sewer repair methods and their advantages.

What Exactly Is Trenchless Sewer Repair

Trenchless drain repair technology is a minimally invasive method to repair sewer pipes around your home. As the name suggests, it’s trenchless. Hence, no digging, intrusion, or disruption occurs during a typical sewer pipe repair or replacement. Various trenchless methods are popular because the work is faster, unlike the traditional methods. Instead of days, the turnaround can be within hours.

Types Of Trenchless Drain Repair Methods

There are several trenchless drain repair methods, each with distinct working features. Here are some of them:

  1. Pipe-Bursting Drain Repair Method:

Also known as torpedoing, this trenchless technology is the perfect intervention for replacing damaged pipes and upsizing them. The method uses a bullet-like bursting head to penetrate and reach a damaged sewer line.

A new pipe is strategically attached to the head, pulling through the older conduit, which breaks away, leaving the new line in place. The method requires a tiny amount of digging, but it is not disruptive to a home’s occupants, as it targets the entry and exit points of the sewer line.

  1. Cured-In-Place-Pipe Lining:

This trenchless method, ideal for crack and leakage repairs, uses epoxy to secure and tightly close a broken pipe internally. A drain plumber uses a unique inflation tool to expand the liner, helping it dry within the drain walls’ shape. The new liner helps to fix any cracks within the sewer pipe. Many drain experts prefer the Cured-in-place-pipe lining because it’s less invasive, less costly, and has a wide range of material options.

  1. Slip Lining:

A drain plumber will often use the Slip Lining trenchless method to place an epoxy liner into a sewer lateral that is already in place. It’s akin to putting a pipe within a pipe to help fix issues like cracks and leakages. The technology featuring plastic material requires excavation at the pipe’s entry and exit points to initiate the repairs.

  1. Spray Lining And Brush Coating:

Another trenchless method that uses epoxy or flexible polymer is Spray Lining and Brush Coating. As the name suggests, the drain plumber sprays or brushes the epoxy in the inner part of the pipe to seal cracks and punctures.

What Are The Key Benefits Of Trenchless Drain Repair?

Homeowners always look for a drain repair system that doesn’t cause all the havoc and intrusion typical of old-style trench digging. Thankfully, trenchless technology removes most of the inconvenience. Some of the advantages of trenchless drain repair include:

  1. Minimal Damage To Your Yard:

Most trenchless drain repair methods will only target entry and exit points, leaving your home free and unscathed during the repair process. Again, the modern tools are precise, allowing the smallest space for the pipe to pass through.

  1. The Process Takes Less Time:

Remember when it used to take days to repair a simple sewer pipe? The trenchless sewer repair technology is fast so fixing the less complex pipes issues takes a few hours.

  1. The Trenchless Methods Are Affordable:

Most of the trenchless materials are cheap and readily available, and with the advanced tool, a drain plumber requires minimal additional labor to complete the job, making the entire process less costly.

  1. Quality And Longer-Lasting Results:

Methods such as slip lining and Cured-in-place-pipe lining result in a new pipe within a pipe, while the Pipe bursting method does the entire replacement with a brand new pipe. Whichever way, however, creates longer-lasting solutions to sewer pipe issues.


While trenchless drain repair methods can quickly help fix your sewer line issues, it is prudent to work closely with a professional. An expert drain plumber uses the most advanced tools to identify your drain problem areas and applies the most suitable repair method.
