At N.W. Sewer & Drain, we understand that the thought of sewer or water line repairs often conjures images of torn-up yards, heavy machinery, and weeks of disruption. That’s why we’re proud to offer cutting-edge trenchless pipe repair technology, a modern solution that fixes your underground infrastructure with minimal digging and maximum efficiency.
So, how does this “no dig” magic actually happen? Let’s walk you through what you can expect during a trenchless pipe repair with our experienced team.
1. Thorough Inspection and Diagnosis
Just like any effective repair, trenchless work begins with a comprehensive assessment of the problem. We utilize state-of-the-art sewer camera inspection technology to get a clear, internal view of your affected pipe. This allows us to pinpoint the exact location and nature of the damage – whether it’s cracks, leaks, root intrusion, or corrosion – without disturbing your property. This crucial step ensures we choose the most appropriate trenchless repair method.
2. Choosing the Right Trenchless Method
Based on our inspection, we’ll determine the best trenchless pipe replacement technique for your specific situation. The two most common methods we employ are:
- Pipe Lining (Cured-in-Place Pipelining – CIPP): This method involves inserting a flexible liner, saturated with a special epoxy resin, into the damaged pipe. Using air or water pressure, we inflate the liner, pressing it against the existing pipe walls. A curing process then hardens the resin, creating a brand new, seamless pipe within the old one.
- Pipe Bursting: This technique is used when the existing pipe is too damaged to line. We insert a specialized bursting head into the old pipe. As the bursting head is pulled through, it fractures the old pipe outwards while simultaneously pulling a new pipe into its place.
We’ll explain the benefits of each method in detail, considering factors like pipe material, diameter, the extent of the damage, and site accessibility, to help you make an informed decision.
3. Minimal Access Points
One of the biggest advantages of trenchless repair is the significantly reduced need for excavation. Instead of digging long, disruptive trenches, we typically only require two small access points: one where the new liner or bursting head is inserted and another where the process ends. These access points are usually just a few feet long and relatively narrow, minimizing the impact on your landscaping, driveways, and other structures.
4. The Repair Process
- Pipe Lining: Once the access points are prepared, the epoxy-saturated liner is carefully fed into the damaged pipe. Inflation then molds the liner to the pipe walls. The curing process can take a few hours, after which the newly formed inner pipe is strong, durable, and resistant to leaks and root intrusion. We then reconnect any service laterals (smaller pipes that branch off the main line) using specialized robotic cutters, all done remotely through the access points.
- Pipe Bursting: After creating the access points, the bursting head, attached to the new pipe, is inserted into the old pipe. Hydraulic or pneumatic power is used to pull the bursting head through. The old pipe is broken apart and pushed into the surrounding soil, while the new pipe seamlessly takes its place. Once the new pipe is fully installed, it’s connected to your existing plumbing system.
5. Quality Control and Inspection
After the trenchless repair is complete, we conduct another thorough camera inspection to ensure the new pipe lining or replacement is seamless, properly installed, and free of any defects. This step guarantees the quality and longevity of our work.
6. Site Restoration
Because trenchless repair involves minimal excavation, the site restoration process is typically quick and straightforward. We’ll backfill the small access points and ensure the surrounding area is left clean and tidy, often leaving your property looking much the same as it did before the repair.
