Trenchless Sewer Pipe Repair


Trenchless sewer repair is a method of repairing sewer pipes without destructively digging and removing large portions of flooring, foundation, and walls to expose the building’s pipes. Trenchless pipe repair structurally restores an existing pipe internally by using the failed or deteriorated pipe as a host, rather than by disruptive, costly trench digging followed by conventional pipe repair and subsequent restoration of impacted surfaces (floors, walls, foundation, cabinetry, etc.). 

The term “trenchless” by definition simply means “without trenches.” Imagine digging a long, deep path directly through the very foundation your building stands on. This conventional pipe repair practice, though widely used throughout the twentieth century and into the present, can jeopardize the integrity of your building’s slab. It also creates the need for extensive follow up repairs to the building once the plumbing work is completed. Thanks to trenchless technology, this is no longer a necessary risk or added expense.

Gentle on Your Property

With trenchless repair, your existing plumbing cleanout (usually located outside your home) and small access points are tapped to restore your drainage pipes from the inside. Usually, portions of inspections and repairs can be administered through the toilet lines – the toilet is removed during service, then reinstalled – or a rooftop vent stacks. With trenchless, the impact on your property is as minimal as possible.

How trenchless pipe repair works:

After your sewer lines are thoroughly inspected and hydro and/or mechanically cleaned, a high-tech, flexible, epoxy-saturated tube (liner) is installed directly into your existing drainage pipes. The epoxy cures (hardens) to form a new structural line – essentially creating a new pipe within the old pipe. It is completely sealed and free from all of the previous issues the original pipe contained.

It does not matter if the old pipes had cracks, holes, channeling, age deterioration, scaling, or root intrusion. In most cases, if a substantial portion of the original pipe is intact, trenchless pipe repair can be used effectively.

Since the liner (tube) starts out flexible, it’s able to navigate around most common bends, plumbing connections, even diameter changes. And once it’s hardened, the liner is 100% sealed and solid, locking out all of the old issues and forming a new, structural surface.

The new liner has a life-use expectancy of 50 years! The epoxy liner’s surface is smoother than many older materials which may also enhance ease of use and flow capacity.

Once the new pipe lining is installed, specialized robotic equipment is guided through the pipes to reopen branchlines. This fascinating equipment has live cameras for the operator to view inside the sewer lines and is controlled remotely by a robotics technician. The reinstatement openings verify that the entire drainage system is restored and functions optimally.

Book Your Video Inspection

Our process starts with an in-depth assessment of your existing pipes. We use advanced technology to capture detailed measurements and conditions of your property’s pipes and build a streamlined plan to repair any damaged sections. Our inspections are much more specific than a plumber’s video, but we are always happy to review any current videos you may have.

What makes trenchless sewer repair better than traditional sewer repair methods?

Trenchless sewer repair eliminates the need for large-scale destruction of floors and landscaped areas to conventionally replace the damaged pipes, the costs associated with replacing those surfaces, and limits the exposure to health and environmental risks created by major sewer excavations.

When is the city responsible for sewer lines and sewer backups?

Individual municipalities have varying rules regarding the line where private property (including underground drainage) becomes public property. Generally, your private sewer main, or lateral, becomes the responsibility of the city at the tap to the city sewer. Blockages and backups in the city sewer system can cause backups on private property, so identifying the location of the blockage is very important as it relates to responsibility.

How long does it usually take to do a trenchless sewer repair job?

In residential homes, a good rule of thumb is “one liner per day.” For example, if your home has a building main, two bathrooms, a kitchen and a laundry, that is five individual liners, hence five days of work. On large-scale commercial or high-rise condominium projects, more aggressive timelines are typical, with anywhere from two to four liner installations a day.

Is there a warranty on the work that is done and the materials?

Pipelining Technologies offers a full five (5) year parts AND labor warranty on every pipe lining job. This is four years more than a conventional Plumber’s one-year warranty and pipe lining carries a transferrable minimum fifty (50) year life-use expectancy.

Would we have to leave the home or business while the work is being done?

No. Pipelining Technologies works to stagger brief water shutoffs in a way that residential customers will have some facilities to use each day of the project. Since pipe lining can be performed in a much shorter timeframe than pipe replacement, there are typically only a few days of slight inconvenience in comparison to several weeks of water shut off with conventional pipe replacement.

Does trenchless sewer repair work on tall buildings such as apartments or condominiums?

Lining of vertical stacks in high-rise buildings is amongst the most cost effective and time saving applications of trenchless pipe lining, also known as CIPP, cured-in-place pipe. Conventional replacement of a vertical stack on a building of significant height can take weeks, even months to complete, and the residents are without water to the affected facilities for the entire time. Pipe lining can accomplish the same job in two days by lining from the roof continuously to the underground with little to no need to enter individual units.

Additional Benefits

The environmental benefits of trenchless pipe rehabilitation are another feature. Since there is no need to remove old piping, large amounts of hazardous waste are not harvested from within your home or business. There is very little waste produced with trenchless methods of pipe repair.

Compared to conventional pipe replacement’s invasive procedures, which oftentimes requires total service shut down and residents to move out while work is being done, trenchless repairs take about one day per line, on average.

Water shutoff is brief and, in general, there will always be a toilet available for use during trenchless repair with a reputable company.

By removing most, if not all, of the inconveniences of pipe repair – destruction, long repair times, hazardous waste, lengthy water shutoffs, major foundation reconstruction – trenchless sewer repair has become the method of choice for property owners throughout the world.

Trenchless Technology Uses

Trenchless pipe repair methods have been trusted by nearly every municipality in the United States for use on large-diameter pipes running under highways, waterways, and historical areas. Today, small-diameter sanitary sewer pipes found in residential, condominium, commercial, and industrial properties benefit from the reduced time, minimal impact, and cost-savings of trenchless technologies.

3-Steps to Trenchless Pipe Lining

Video Inspection

We begin all pipe lining projects with a detailed forensic study of the existing pipe system by means of a HD video camera inspection. A digital copy of the video is yours to keep.

Sewer Pipe Cleaning

The sewer system is cleaned using hydro (water) jetting and/or a mechanical cleaning process that removes scale, buildup, debris, blockages and restores flow in the existing pipes. 

Lining & Reinstatement

Your cleaned pipes are lined with an epoxy saturated tube (liner). The tube hardens and the new structural line becomes stronger than PVC. Robotic equipment is used to reopen branch lines.
