Trenchless Pipe Lining

Proudly serving the greater Duluth and Superior area.

Sewer line lining, also known as cured-in-place pipe (CIPP) lining, is a trenchless method used to rehabilitate damaged or deteriorating sewer pipes. This technique involves inserting a flexible liner coated with resin into the existing sewer line. The liner is made of materials such as felt or fiberglass and is impregnated with a specialized resin that hardens and creates a durable new pipe within the old one.

The process begins with a thorough cleaning of the existing sewer line to remove any obstructions or debris. Then, the liner is inserted into the pipe and inflated using air pressure to conform to the shape of the old pipe. The resin is then cured using a UV light, allowing it to harden and adhere to the inside of the existing pipe within minutes. Once cured, the liner creates a smooth, seamless surface that restores the structural integrity of the sewer line, seals cracks or leaks, and improves flow capacity.

Sewer line lining offers several benefits. First and foremost, it eliminates the need for extensive excavation, minimizing disruption to landscapes, driveways, or other structures. The process can be completed with minimal digging, usually requiring only small access points.

Additionally, sewer line lining is a cost-effective solution compared to traditional methods that involve full pipe replacement. It reduces labor and material costs while saving time. The new liner is resistant to corrosion and root intrusion, extending the lifespan of the sewer line. Furthermore, sewer line lining restores the flow capacity of the pipe, improves overall system performance, and helps prevent future issues. It is a highly efficient and durable solution for rehabilitating damaged sewer lines while minimizing the impact on the surrounding environment.

Pipe Lining Method

The Process

We dig one hole

The first step in the pipe lining process is the creation of a small hole at the site of connection to your home's plumbing.
We clear the old line

Next is the clearing of any roots, blockages or debris left in the old line. Using a variety of drain cleaning tools from chains to brushes, we create a smooth surface for the lining to adhere to.
We prep the new lining

The new lining is filled with a resin that is spread evenly throughout, and cut to the exact length of your servive line. Once prepped, the lining is insertered into an inversion trough for the final stage.
We install and cure

Using compressed air, the prepped lining is inserted into the old pipe, inside-out. Once in place, the resin is cured using a high-powered UV light. In as little as 10 minutes, your new service line is hardened and ready for use!

Chet and the whole Contour Inc. team were amazing. I had called 5 contractors to get estimates and 2 weeks later none had gotten back to me. I then called Chet and he was out the next day. I was very happy with the timeliness of the work and most importantly, they left my yard and driveway in perfect condition. Call these guys! You won't be disappointed.
