Trenchless sewer pipe repair, also known as trenchless pipe rehabilitation or trenchless sewer replacement, is a method used to repair or replace underground sewer pipes without extensive excavation. Traditional sewer repair methods involve digging trenches to access and replace damaged pipes, which can be disruptive, time-consuming, and costly. Trenchless techniques offer a more efficient and less invasive alternative, minimizing property and infrastructure disruption while effectively repairing or replacing sewer lines.

The Need for Innovation

Traditional sewer repair methods, involving extensive excavation, disruption to landscapes, and potential damage to infrastructure, have long been frustrating for property owners and municipalities alike. Beyond the inconvenience, the financial burden of restoring property and repairing landscaping can be significant.

Enter trenchless sewer pipe repair. This innovative suite of techniques represents a paradigm shift in the industry, providing efficient and non-invasive solutions to various sewer pipe problems. From minor leaks to full-scale pipe replacements, trenchless methods offer a more streamlined and cost-effective approach, ensuring minimal disruption to daily life and surrounding infrastructure.


There are several Trenchless Sewer Pipe Repair methods, each suited to different situations and types of damage:

Pipe Lining (Cured-in-Place Pipe, or CIPP):

Pipe lining involves inserting a flexible, resin-coated tube into the damaged sewer pipe.

The tube is then inflated, and the resin is cured using heat or UV light, creating a new, seamless pipe within the existing one.

This method can repair various issues, including cracks, corrosion, and minor to moderate-sized leaks.

It preserves the original diameter of the pipe and can be used in pipes with bends and curves.

Pipe Bursting

Pipe bursting is used when the existing sewer pipe is severely damaged or collapsed. A new pipe, typically made of high-density polyethylene (HDPE), is pulled through the old pipe, breaking it apart.

This method effectively replaces the old pipe with a new one of the same or larger diameter without excavation along the entire length of the pipe. It’s handy for replacing pipes in areas with landscaping, driveways, or other structures that would be expensive or difficult to excavate.

Slip Lining

Slip lining involves inserting a smaller-diameter pipe (usually made of PVC or HDPE) into the damaged pipe. The new pipe acts as a liner, sealing leaks and reinforcing the old pipe.

This method is suitable for pipes with moderate damage and can improve flow capacity without significantly reducing the diameter of the pipe.

Benefits of Trenchless Sewer Pipe Repair

Minimal Disruption: Trenchless methods require only minor access points, minimizing disruption to landscaping, roads, and other infrastructure.

Cost Savings: While initial costs may be higher than traditional methods, the overall cost savings can be significant due to reduced labor, equipment, and restoration expenses.

Faster Completion: Trenchless repairs can often be completed more quickly than traditional methods, reducing downtime and inconvenience for property owners.

Durability: Trenchless waterline repair often results in a stronger, more durable sewer pipe, extending its lifespan and reducing the need for future maintenance.


However, trenchless sewer pipe repair may only be suitable for some situations. Factors such as the extent of damage, pipe material, and accessibility may influence the choice of repair method. It’s essential to consult with a qualified sewer repair professional to determine the most appropriate solution for your specific needs.
